1 Executive Summary Deployment of Digital Railway (DR) technologies - European Train Control System (ETCS), Traffic

Management (TM) and Connected Driver Advisory System (CDAS) - on the GB rail network

requires modifications to existing industry and Network Rail company standards. Working within the

DR Interim Joint Delivery Group (IJDG), a team of subject matter experts from three different

suppliers and Network Rail reviewed the current standards library and identified the changes

needed to support DR roll out as well as how to implement those changes in a cost effective

manner.

The key recommendation from this work is that a suite of new DR standards should be developed to

complement, and where necessary take precedence over, existing standards. Analysis of the gaps

in the current library and lessons learnt from previous DR projects indicate that this is a more cost

effective approach to addressing gaps and conflicts in standards than attempting to update them on

an individual basis. The new standard suite should address the following areas (listed in order of

decreasing priority).

1. The processes by which DR systems are designed and installed.

2. Commissioning DR systems, management of DR geographic data and parameters.

3. How ETCS functionality is applied in GB and associated operational procedures managed.

4. Consistency of TM user requirements and interfaces.

5. Maintenance of DR technologies.

6. Requirements for supporting telecommunications systems.

7. User requirements for CDAS.

2 Introduction

2.1 Joint Development Group (JDG) Building on the success of the previous Early Contractor Involvement (ECI) work streams, the Digital

Railway Programme (DRP) developed the concept of a Joint Development Group (JDG). The JDG

seeks to leverage the breadth and depth of technical competencies that exist in the supply chain to

inform a diverse industry opinion and respond to novel and ambiguous problem statements that

emerge within the DRP. The core concept behind the JDG is to bring together a community of

suppliers with a wide range of skills and capabilities, each able to be called upon / invited to support

the DRP’s development activities. This new way of working allows the DRP to utilise the diversity of

thinking from the supply chain on a variety of problem statements. For the remainder of CP5, the JDG

will be in its interim phase (IJDG) during which the concept and operating model will be validated prior

to a solution being locked in CP6.

A combination of ECI led to the JDG end to end process being developed. Figure 1 shows each step

with descriptions.

Figure 1: JDG commissioning process

Customer will approach JDG core management team with a problem statement. The JDG work with the customer to convert the problem statement into a capability request.

Instructions regarding the submission process will be included in the capability request email. Suppliers will be asked to populate a submission form

The core management team will issue the capability request, evaluation criteria, submission form and NR03 construction services agreement via email

All competing suppliers will be notified of the evaluation outcome and awarded suppliers will be issued an NR03 construction services agreement for execution. A kick off meeting is convened to capture deliverables and assign responsibilities.

JDG core management team use a simplified process whereby only submission forms are evaluated. There will be no interview component

2.2 Project Background The DRP is developing a generic suite of ‘Customer Requirement Specifications (CRS)’ to provide a

baseline to ensure that the use of Digital Railway (DR) technologies on any individual deployment

project will integrate and be compatible across route boundaries. These DR systems will not exist in

isolation on the rail network and will need to interact with a variety of other systems, which may include

both existing systems and DR systems.

The Generic CRS are intended to promote the development of technically, operationally and

environmentally compatible solutions, which are safe and secure, and which could be deployed

across Great Britain’s rail network to maximise the benefits of adopting DR technologies. The Generic

CRS include functional and non-functional process requirements that will be utilised to form the project

specific requirements for a DR application including the applicable ‘Engineering Rules’.

Engineering Rules, in the context of the CRS, can be described as the relevant Network Rail

Company and Industry technical, process and engineering management standards, which are still

deemed applicable for the delivery of the following DR technologies:

• European Train Control System (ETCS) Level 2 – No Signals,

• Traffic Management (TM),

• Connected Driver Advisory System (CDAS).

2.3 Problem statement This report has been produced in response to the following problem statement that Network Rail set

the Interim Joint Development Group (IJDG).

‘Limited work has been undertaken by Network Rail to review, identify and adapt current

project delivery processes and Command Control and Signalling standards to suit ETCS, TM

and CDAS applications. Network Rail is keen to leverage the interim Joint Development

Group (IJDG) to enable clarity and definition of the applicable Engineering Rules to project

and programme teams across its business.

Whilst it is understood that certain commercial arrangements may have an impact on the

delivery of such DR schemes, for this exercise it will remain a generic activity. It is assumed

that schemes with a mixture of DR and conventional signalling technologies are excluded

from this exercise. However, it is noted that some findings for ETCS provision, as a result,

may be applicable.’

2.4 System under consideration For the purposes of this study, the system under consideration is the ‘end state’ DR, i.e. a line

signalled with ETCS Level 2 where lineside signals are not provided and equipped with TM and

CDAS. Figure 2 illustrates the functional architecture of this system. For further details see Ref. 1.

This Report

Unrestricted 11

Railway industry (Ref. 2) and Network Rail company standards (Ref. 3) were taken as inputs along

with Network Rail’s preliminary assessment (Ref. 4) identifying standards impacted by ETCS. The

first task was to Update and Extend this earlier analysis as follows:

• independent ‘sense check’ of earlier analysis;

• update to reflect new standards / standards changes between 02/10/2015 (the date of the

preliminary analysis) and 26/06/2018 (the date of the current analysis);

• extension to identify standards potentially impacted by TM and CDAS as well as by ETCS.

This task was conducted at a high-level based on standards titles with the aim of removing

standards that are definitely not impacted by DR technologies (ETCS, TM, CDAS) rather than

definitively identify those that are.

Gap analysis of standards library: the list of standards applicable to DR was then reviewed to

identify gaps in the coverage of existing standards with respect to DR schemes. Gaps in similar

areas were grouped together to form proposed new standards.

Categorisation of standards and assignment to Subject Matter Experts (SMEs): in parallel, the

existing standards potentially impacted by DR were split into the following categories.

• Industry Standards

• Network Rail company standards in category 1: Scheme Development – Design

• Network Rail company Standards in category 2: Detailed Design

• Network Rail company Standards in category 3: Implementation / Construction / Testing

• Network Rail company Standards in category 4: Maintenance / Operations

• Network Rail company Standards incategory 5: Traffic Management

• Network Rail Company Standards in category 6: Telecoms

• Network Rail Company Standards in category 7: Other – processes, configuration

management, method of deployment, electromagnetic compatibility, etc.

• Network Rail Company Standards category in 8: Interfaces with conventional signalling

Industry standards and Network Rail company standards in categories 1 – 7 were each assigned to

an SME for the particular category.

Standards in category 8 were not assessed further as they are not impacted by the DR end state –

the system under consideration in this review. They are, however, likely to be impacted by practical

DR schemes through fringes with other signalling technologies and / or through overlay / underlay

solutions that use lineside signals alongside ETCS.

Initial filtering of standards by SMEs: each SME looked at the contents of each of their assigned

standards to assess whether it was relevant to each of the DR technologies and asses whether a

detailed gap / conflict analysis review was required.

SME clause by clause analysis of filtered standards: where a detailed gap / conflict analysis

review was required, the SME read the standard and provided a section by section / clause by

clause commentary on gaps with respect to DR technologies and the impact of those gaps.

2.7 Outputs In accordance with requirements initially placed on the IJDG, this report provides the following

outputs.

• Review all Command, Control and Signalling (CCS) company and industry standards

including their content and clauses.

Sections 3.2 lists the standards that were reviewed. Section 4.2 describes where a clause

by clause review was carried out on specific standards that were identified as relevant to DR

in the initial review.

• Undertake a GAP analysis / impact assessment of all current CCS company and industry

standards.

The outputs of gap analysis / impact assessment are summarised in Sections 3.3 (gaps in

standards library) and Section 4.3 (gaps in individual standards). Further details are

provided in Appendices A & B.

• Provide a definition of the standards applicability to DR schemes with respect to the DR

technologies described above.

Section 6.2 recommends proposed new standards applicable to the DR technologies

described whereas Section 4.2 lists the existing standards that are applicable.

• Identify conflicts and requirements for deviation.

Sections 6.3 and 6.4 identifies conflicts in standards applicable to DR technologies.

Creation of new DR stations is recommended as the most economic path for addressing

deviations.

• Review all process and engineering management standards currently undertaken in the

delivery and assurance of conventional CCS projects.

Process and engineering management standards were considered, along with CCS

standards, as described in Sections 3.2.

Unrestricted 14

In accordance with DR’s requirements for this GAP analysis / impact assessment report, the

following topics are addressed.

• Review of all current standards and classification as to whether the standards require

change or are not applicable in consideration of the delivery of the following DR

technologies:

o ETCS Level 2 – No Signals,

o TM (All types),

o CDAS.

See Sections 3 and 4.

• Lessons learnt from previous DR projects.

See Section 5.

• Set of recommendations such as new standards required.

See Section 6.

• Methodology for the change or amendments of current standards.

See Section 7.

• Worked example of how this change could occur.

3 Gap Analysis of Standards Library

3.1 Overview This section describes the gap analysis conducted on the existing Standard Library and output

‘Gaps in Standards Library and their impacts.’

3.2 Standards reviewed The following standards were reviewed.

• All Railway Group standards and Guidance Notes.

• All Rule Book Modules.

• All Railway Industry Standards and Industry Good Practice Guides.

• All Industry Codes of Practice.

• All Network Rail Company standards listed in the Network Rail preliminary assessment.

• All Network Rail Company standards published after 02/10/2015 (the date that the

preliminary assessment was carried out).

Note that the Network Rail preliminary assessment listed only ~10% of all Network Rail company

standards. The remainder had been identified as not-relevant to DR and have therefore not been

considered further. A full list of these excluded standards is provided in Appendix C.

3.3 Summary of gaps identified & their impact The delivery team identified the following areas where standardisation across the Great Britain (GB)

rail network would be beneficial, but is not addressed by existing standards. These areas are listed

in order of decreasing priority, as assessed by the delivery team. Some of these requirements may

need to be Notified National Technical Rules (NNTR) to avoid incompatibilities between trackside

and on-board ETCS equipment.

1) The processes by which DR systems are designed and installed

As novel, highly complex, software based systems, the processes needed to safely and

reliably designing and installing DR systems are markedly different from those used for

conventional signalling. Whereas the later are built on the cumulative experience of almost

200 years of railway operation, ETCS, TM and CDAS technologies are still relatively new

and embody significantly greater levels of functionality.

There is currently a gap in the standards library whereby processes for designing and

installing ETCS, TM and CDAS are not specified. This gap extends to the management of

Euroradio keys, ETCS identities, business change and operational procedures.

The impact of this gap is that projects must either apply existing processes or develop their

own processes. The former could introduce safety or reliability hazards where processes

designed for conventional signalling are inappropriately applied to DR schemes. The latter

would tend to introduce unnecessary cost and delay as process development work would be

duplicated between multiple projects.

Unrestricted 16

2) Commissioning DR systems, management of DR geographic data and parameters.

As well as needing different processes for design and installation, DR systems also require

different processes for commissioning into operational service. Furthermore, unlike

conventional signalling systems which need only limited geographical configuration data, DR

technologies require an accurate and up-to-date geographic representation of the railways

that they supervise. Generating and maintaining such geographic representations requires a

rigorous approach to specification, collation and management of geographic infrastructure

data. In addition to geographic data, DR technologies also entail many new identities and

parameters

There are currently gaps in the standards library whereby processes for commissioning

ETCS, TM and CDAS technologies are not specified and neither are robust processes for

managing the geographic data and parameters that they need.

The impact of the commissioning gap is similar to that of the design and installation gap:

projects either apply inappropriate existing processes or incur unnecessarily time and

expense developing their own. The initial impact of the data and parameters gap is

additional expense and delay due to DR projects being provided with inadequate or

unsuitable data for their needs. The long term impact is poor reliability and possible safety

hazards with significant remedial expense where data is not adequately maintained.

3) How ETCS functionality is applied in GB and associated operational procedures

managed.

A key strength of ETCS is its versatility in terms of the range of functions it supports and the

flexibility with which they can be implemented. However, without national standardisation on

how these functions are implemented, different ETCS projects could implement the same

function in very different ways or vary significantly in the functions that they use.

There is currently a gap in the standards library in terms of how and where different aspects

of ETCS functionality should be used.

The impact of this gap is potential inconsistencies in behaviour of different DR deployments

in different areas. Such inconsistencies are likely to cause operator confusion with

consequent safety and performance hazards.

4) Consistency of TM user requirements and interfaces.

Different TM technologies are provided by different suppliers, each with slightly different

functionality user interfaces and interfaces to other systems.

There are currently gaps in the standards library in terms of specifying standard TM user

requirements across Network Rail infrastructure and in terms of specifying standard

interfaces between different TMs and between TMs and other systems.

Unrestricted 17

The impact of these gaps are incompatibilities between different TMs and other systems and

inconsistencies in how suppliers’ TM products are tailored to the GB market. The former is

likely to incur unnecessary operator training expense and risk of error. The latter will tend to

result in additional project costs and delays associated with systems integration and the

possibility that some project interface requirements cannot be delivered.

5) Maintenance of DR technologies.

As highly complex, software based systems, the maintenance requirements for DR

technologies differ significantly from those for traditional electro-mechanical signalling

equipment. Management of hardware obsolescence, software updates and data are key as

are Information Technology (IT) skills to interrogate to the equipment.

There is currently a gap in the standards library in terms of how maintenance of DR

technologies should be planned and managed.

The impact of this gap is higher whole-life cycle costs as maintenance arrangements are

inadequately planned during deployment of DR technologies.

6) Requirements for supporting telecommunications systems.

ETCS Level 2 (as used by DR) requires a radio network to carry ETCS messages between

trackside and train-borne signalling equipment. Currently Global System for Mobile

Communications – Railways (GSM-R) radio networks are specified though other

technologies are likely to be required to address GSM-R obsolescence and capacity

limitations. As such, deployment of ETCS Level 2 places requirements on radio networks in

terms of communication channel availability, quality of service and technologies employed.

Similarly deployment of CDAS requires a (currently unspecified) radio bearer to convey its

message between trackside and train-borne equipment as does TM for communication with

handheld devices used by track workers. TM is also dependent on a supporting fixed

telecommunications network for which it has its own requirements in terms of connectivity,

bandwidth and quality of service.

Cyber security is a key consideration for all modern computer based signalling technologies,

including DR technologies, as they are potentially vulnerable to cyber attack.

There is currently a gap in the standards library in terms of how telecommunications

functional, performance and cyber security requirements for DR deployment projects should

be determined and specified.

The impact of this gap is the risk of signalling projects receiving inadequate

telecommunications networks for the technologies that they are deploying. This in turn could

lead to significant expense and delay to address the shortfall.

Unrestricted 18

7) User requirements for CDAS.

As with TM, different CDAS technologies are provided by different suppliers, each with

slightly different functionality.

There is currently a gap in the standards library in terms of specifying standard CDAS user

requirements across Network Rail infrastructure.

The impact of this gap is inconsistencies in the operational deployment of CDAS with

consequent risk of operator confusion and poor performance.

Unrestricted 19

4 Gap Analysis of Individual Standards

4.1 Overview This section describes the analysis of individual standards within the Standard Library, conducted in parallel with the gap analysis of the Standards

Library described in Section 3. The first step in analysing individual standards was to identify which are applicable to DR. This lead to the output,

contained in Section 4.2: ‘Standards Relevant to DR.’ The next step was to conduct a clause by clause analysis of each standard leading to the output

‘Gaps / conflicts in specific standards & their impacts:’ contained in Sections 4.3 and 4.4.

4.3 Summary of gaps / conflicts identified Gaps / conflicts in existing standards were identified in the following areas.

• Delivery processes: design and installation processes specified in standards are inappropriate for development and deployment of software based DR technologies. These gaps could be addressed by the proposed new first priority standards described Section 3.3.

• Commissioning processes and data management: commissioning processes specified in standards are inappropriate for DR technologies. Similarly, standards do not specify how geographic data maps or DR parameters should be managed. These gaps could be addressed by the proposed new second priority standards described Section 3.3.

• Application ETCS functionality: standards are written from the perspective of signalling by lineside signals. As such, there are gaps / conflicts in terms of defining how ETCS functionality is applied in GB, notably in the following areas.

o Terminology - standards use terms relevant to lineside signals (e.g. ‘signal,’ ‘aspect’) for requirements that could also apply to ETCS movement authorities (MAs) / signage.

o Route classes - no provision is made for ETCS classes of routes in addition to conventional classes of route nor how conventional routes would map to ETCS routes.

o Driveability - driveability requirements for ETCS schemes are undefined.

o Overrun risk - requirements for overrun risk assessment are from the perspective of trains passing signals at danger and do not consider risk of trains passing ETCS block markers in degraded mode operation.

o Approach locking - difference in how approach locking is implemented in ETCS schemes are not reflected in standards.

o Use of ETCS functionality as an alternative to conventional controls - standards do not allow for

▪ use of ETCS position reports to disengage route entrances; ▪ use of ETCS position reports to prove train at a stand for the purposes of

5 Lessons learnt from existing DR projects The Engineering Rules delivery team contained a number of SMEs who had experience of ETCS

projects overseas and in the UK. The team agreed that the issues concerning standards and

engineering rules encountered on those projects would help inform the recommendations of the

group. The following projects were considered.

• Sydney Australia: this project is still in the implementation phase and involves the

application of an ETCS Level 1 hybrid solution to provide speed supervision only for the

Transport for New South Wales commuter network. Note: signal passed at danger (SPAD)

and overrun protection functionality being retained by the mechanical train stop system.

• Cambrian: The first UK ETCS Level 2 deployment in North Wales.

• Tilt Authorisation and Speed Supervision (TASS): the West Coast Main Line TASS

project.

• Thameslink: the recent ETCS Level 2 overlay on the Thameslink central corridor.

• Crossrail: the current Crossrail ETCS Level 2 overlay project between Paddington and

Heathrow.

• Modular Signalling: the project to develop and deploy new Modular Signalling technologies.

• London Underground Design Handbook: outcome of update to standards and guidance in

the late 1990s.

5.1 Sydney Australia

5.1.1 Issues

Signalling standards and engineering rules in the Sydney and New South Wales (NSW) region are

considerable and cover all areas of signalling. Transport for NSW (TfNSW) is responsible for all

transport in the state. Previously the NSW railway was run by a company called Railcorp, who was

also responsible for all railway standards. However, Railcorp was split in 2013, and Sydney Trains

now runs the local commuter services in the Sydney area. TfNSW has a department named Asset

Standards Authority (ASA) that is now responsible for all standards.

The signalling standards and engineering rules come under the following types:

• ASA Standards,

• Engineering Standards (existing Railcorp standards),

• Engineering Specifications,

• Engineering Guidelines,

• Engineering Procedures (specific processes),

• Engineering Manual (procedures and work instructions),

• Design Guidelines.

The new ETCS Level 1 system is spread across all the different standard types, in order to integrate

with the existing standards structure, as well as take account of the new ASA organisation. In

addition, there is also a number of project specific standards that have been produced by the project

team that cover the design and implementation rules for the project.

Unrestricted 34

Consequently, the same information is repeated in a number of documents, and it is difficult to find

the correct information required for each design task. The information also conflicts between

documents (such as balise identity numbers) and the project documents are updated frequently as

the project is rolled out and lessons are learned (such as control table layout changes). There is

also a guide written by the equipment supplier (who will undertake the data design) that does not

match the latest project updates.

5.1.2 Lesson Learned

The project team have tried to fit in with the existing standards structure, and also provide project

specific guidance information as well as guidance information from the equipment supplier. This has

lead to numerous documents that have exactly the same information and system description, but

due to updates there is inconsistencies between the documents. This set up also makes it difficult to

find the correct information for the different design documentation.

The lesson learned here is not to fit the new DR standards amongst the existing standards set up,

or with the existing standards organisations, but to have the standards under the control of the DRP

only. This will allow simpler management and quicker updates as lessons are learned during the roll

out.

5.2 Cambrian Early Deployment Scheme (EDS)

5.2.1 Issues Network Rail produced a number of Requirements Specifications for the Cambrian EDS project that

were subsequently reviewed by the supplier, Ansaldo. The resulting updates meant that the system

requirements were changed to meet the supplier’s solution.

Network Rail also intended to update the existing standards to cover the ETCS Level 2 system, but

this was never achieved due to lack of resources and timescales to undertake this considerable

task.

A lessons learned meeting was held after the Cambrian project was complete, but this only

focussed on the project lessons, not the operational and maintenance issues that have occurred

since commissioning. Significant post commissioning issues include the following.

• Driveability: the static speed profile in the dynamic loops at Welshpool was determined by

the maximum permissible speed permitted by track geometry. The result of this was a

cluttered Driver Machine Interface (DMI) display and drivers choosing to smooth the profile

by ignoring all of the peaks and driving at a constant speed. When the opportunity arose in

conjunction with other work the profile was altered to a single speed for almost the entire

length of both loops which in turn simplified the DMI display and matched the driver’s

technique.

In terminal station on the Cambrian the approach line speed is continued up to the buffer

stop, this area of rail is often subject to oil spills, rust and other contamination making it an

area of poor adhesion. Consideration could be given to setting the speed at a similar level

as company defensive driving policies require or configuring approaches as poor adhesion

areas to reduce the likelihood of a train sliding into the buffer stops.

Unrestricted 35

• Degraded mode operation: degraded mode speed indicators (DMSI) are provided to inform

the driver of the maximum speed a train may be driven in a degraded mode. The Rule Book

requires the speed of a train not to exceed 25 km/h over any points, switch diamonds or

swing nose crossings, at few locations the last DMSI the driver encountered displayed a

speed higher than 25 km/h. To provide consistent and unambiguous information to drivers

additional 25km/h DMSI were installed to cover all points.

At Welshpool when a train approached block marker 1051 it first passed a 40 km/h DMSI

which was of no relevance to the driver of a train operating in FS mode. If the same train

was then issued with a written order to proceed beyond 1051 there was nothing to remind

the driver that the 80 km/h ceiling speed no longer applied. As a consequence it was agreed

to relocate the DMSI at the marker. Where the degraded mode speed is lower than the

ceiling speed consideration should be given to placing a miniature reminder DMSI below the

block marker.

• Incident management: when investigating allegations against or failures of the system it

was known that details of events were recorded with a timestamp but such data was either

difficult to access or knowledge of how to locate it was lacking. Two specific changes were

made to assist the maintainer. The first was the creation of a window the content of

messages sent to the train, the most commonly used is the content of an MA. The other

was an interrogation facility to list errors reported by trains when reading balise telegrams.

This facility allows for faulty balise to be identified and replaced before a service affecting

failure results. Another advantage is that the majority do not need their telegrams to be read

when undertaking routine maintenance reducing the time on track for maintenance staff.

There is probably a need to train critical staff to a more advanced level than is traditionally

applied of how to access stored data that may only be required infrequently but could be

essential to restoring the system following an allegation.

• DMI: a number of problems were encountered where it became difficult for drivers to read

the DMI screen. This problem is associated with the Class 158 retrofitted cabs so could

affect other cabs where the DMI is fitted into a conventional drives desk.

1. The screen flickered repeatedly from day to night intensity as it responded to changes in

the light entering the cab which distracted the driver. This was rectified by the installation

of a DMI that ignored short duration changes to the light entering the cab so eliminated

the problem.

2. The ATW drivers uniform includes a white shirt. When sunlight entered the cab through

the windscreen it reflected off the shirt onto the DMI screen, this was eradicated by

changing the uniform shirt to dark blue.

3. The DMI was washed out when sunlight entered the cab through the side widow. To

prevent this the fixed pane of glass was covered with a dark filter. The opening section

of the window had a sliding louvered screen added to allow fresh air to enter the cab

when open and still block the sunlight.

• Discipline boundaries: on a number of occasions where signalling communications passed

over the Fixed Telecoms Network the time to repair equipment was extended. This occurred

because the onsite signalling technicians could not easily identify which side of the

Signalling / Telecommunications boundary the root cause of the fault was

Unrestricted 36

located. Assuming Network Rail (NR) is to continue using staff that are discipline specific, it

is suggested they specify test / monitoring equipment as part of the deployment to allow the

onsite technician to identify which side of the boundary a fault exists. This in turn will allow

for the correct teams to be mobilised and speed defect rectification.

• Competence: Signal Fault Investigation (SFI) Level 2 and 3 is an area where competence is

difficult to gain and maintain. Because ERTMS is a new system to most areas of the UK rail

network and not just a variation of the classic systems this makes gaining skills and

knowledge challenging for staff in senior positions. NR should consider as part of any

further deployment how to train these staff and maintain their knowledge of this critical role

which often requires out of office hours as an on call activity.

As part of any deployment it is recommended that training should not only cover any

employees specific role, but that it should be extended to include cross discipline and inter-

company awareness of the roles of others. The purpose of this proposal is to allow the

information contained in these communications to be clear and easily understood by the use

of common terms and phrases.

5.2.2 Lesson Learned The requirements specifications should not suit a supplier specific solution. The Engineering Rules

or deployment guidelines that provide information on how to meet the requirements need to be

referenced back to the DR Customer Requirements so that there is traceability.

Also, the attempt to have the standards updated did not work due to the number of stakeholders

involved and the subsequent timescales and resources required for the update process. Therefore a

separate set of DR standards/engineering rules are simpler to achieve.

The operational and maintenance issues that have occurred on the Cambrian post commissioning

need to be studied as a separate lessons learned activity and incorporated in any new DR

standards and engineering rules.

5.3 TASS

5.3.1 Issues

The TASS project used ETCS balises and ETCS equipment on board the Virgin Pendolino trains to

supervise the tilt authorisation functionality. Separate standards and guidelines were produced for

the TASS system and these contributed to the success of the initial TASS project. They have also

subsequently been applied across multiple projects post initial commisioning where the TASS

system has been affected.


System specific standards and guidelines produced by the project team simplified the

implementation of the project.

Unrestricted 37

5.4 Thameslink

5.4.1 Issues

The Thameslink project also produced their own specifcations and guidelines for the ETCS instead

of trying to produce Network Rail Company Standards. Key specifications included interlocking

principles, control table and scheme plan layouts; these could potentially be adapted for application

on other projects.


System specific specifications developed separately to current standards were successful in

achieving the project outcomes.

5.5 Crossrail

5.5.1 Issues The testing of the ETCS Level 2 system is not covered by existing testing standards, which are

based on individual component or sub-system level of a known conventional signalling system. A

system based process is required for the testing of a DR solution with a focus on generating

evidence to demonstrate that functional requirements are satisfied and interfaces to other system

elements are adequately proven.

The migration of signalling functionality to the train equipment creates new roles to ensure the

onboard system demonstrates compatibility and is integrated into the railway system. Configuration

control is essential in ensuring the operational system is proven and compatible. The train borne

testing roles are likely to be within the Railway Undertaking (RU) organisation as opposed to the

Infrastructure Managers (IM). The system integration must capture the entire system with a role

spanning across the RU and IM organisations.

There is also little or no guidance on how to protect the operational railway utilising DR technology

during the physical site preparatory works for introducing changes to the railway system. This is

specifically relevant to balises, which will be operational immediately they are laid down.

The process for authorising an interoperable railway into revenue service needs to comply with the

EU directive on interoperability (EU 2016/979). This process goes beyond traditional Network Rail

entry into service requirements with additional formalised activities for verification and validation and

safety authorisation. There is little or no guidance on how to alter an operational railway utilising DR

technology and subject to the interoperability regulations. The lack of guidance could result in

projects being unable to demonstrate compliance with the European Union (EU) directive on

interoperability, and this may lead to a breach of the legislation.


The DR engineering rules need to consider the whole installation, testing and entry into service of

the complete system as current standards are not adequate. This needs to include the integration of

the trackside and train borne ETCS systems, and the entry into service guidelines need to consider

the EU directive on interoperability (EU 2016/979).

Unrestricted 38

5.6 Modular Signalling

5.6.1 Issues

Though not an ETCS related project, Modular Signalling was faced with a similar issue regarding

standards changes and how to manage the updates. Modular Signalling decided it was best to have

a separate Modular Signalling Handbook that would be used by modular signalling projects, and

included both standards and guidance in the one handbook. This handbook was jointly produced by

suppliers of modular signalling equipment and Network Rail.


Providing a separate handbook for designated modular signalling projects avoided the need to

review and update many standards. All the required information for a modular project was contained

in one handbook, and this facilitated a simpler update when lessons were learned from the initial

deployment sites. A single handbook also helped the project implementation, as the necessary

information was in one set of documentation.

This way forward may be a model for the DR and avoids the need to update many existing

standards, and places all the DR information in one place.

5.7 London Underground Limited (LUL) Design Handbook

5.7.1 Issues

In the late 1990s LUL were updating their standards and guidance documentation. The approach

taken was to have requirements standards on specific safety related topics, such as interlocking

principles, control systems and depot operation. These requirements documents were backed up by

a Design Handbook that provided guidance on principles, process and application related to the

deliverables required on an LUL project. This included scheme plans, headway charts, wiring

diagrams, etc. An installation handbook and testing guidance documents were also issued.

5.7.2 Lesson Learned This format was well received by engineers as it explained the principles behind the design

application and the production process needed for each deliverable, with the information provided in

one place. The design principles explained related to the different applications on the different LUL

lines. The handbook was also a good introduction and training guide to LUL signalling, particularly

for those new to the underground.

A similar methodology may be suitable for DR, as DR technologies will be new in the UK and

unfamiliar to many engineers.

5.8 Documentation from Previous Projects The delivery team agreed that considerable documentation has already been produced for the

Cambrian EDS as well as the current Thameslink and Crossrail projects being undertaken by NR.

The DR project has also produced a number of reference design documents that contain significant

information on the proposed UK application of ETCS Level 2.

Unrestricted 39

The specifications and documentation already produced by these Network Rail projects should be

reviewed prior to any further Engineering Rules work to determine if sections can be reused or

altered to form the basis of the proposed Engineering Rules Deployment Guides.

Note: All Engineering Rules Deployment Guides must fit in with the DR requirements and

documentation hierarchy and be traced back to the DR Customer Requirements where applicable.

Unrestricted 40

6 Recommendations

6.1 General approach A new suite of DR standards should be created rather than attempting to accommodate DR

technologies through update of existing standards.

Rationale: gap analysis of the Standards Library has shown that the most significant gaps are in

areas that are outside the scope of existing standards, which would be best filled by new standards.

Furthermore, lessons learnt form earlier DR projects indicate that production of new standards for

new technologies is a much more efficient and reliable processes than attempting to adapt existing

standards. Gaps in individual standards could be addressed by these new standards. Conflicts

between existing standards and DR technologies could be managed by giving precedence to the

requirements of the new standards over existing standards for DR technologies.

Unrestricted 41

6.2 Proposed new standards and guidance The following new standards plus associated guidance notes should be produced to fill gaps where

the current standards library does not adequately support deployment of DR technologies.

Rationale: these new standards fill the gaps identified in Section 3.3. Their contents was developed

through brain-storming within the delivery team.

Guidance: note that much of the material for these standards can come from existing DR

workstreams, such as customer requirements specifications and the ETCS reference design.

7 Next Steps

7.1 Introduction A significant number of new standards and updates to existing standards have been identified to

support deployment of DR technologies across the GB rail network. The following are the

recommendations for the next steps.

1. Creation of a dedicated project team to create new standards where required, manage and

deliver the necessary Network Rail company standards changes and liaise with the relevant

bodies for changes to industry standards (e.g. RSSB).

2. Review the output from the IJDG, refine and agree the prioritisation based on the proposed

digital “work” portfolio and risk.

3. Group the new standards as a specific suite of ‘Digital’ standards that take precedence over

other standards when DR technology is being delivered.

7.2 Dedicated Project Team. Given the volume of standards work required and the need for consistent delivery approaches and

system application across projects, the forming of a dedicated project team to manage and deliver

the standards work would be prudent. This core project team would consist of a project manager,

planner and at least two engineers to produce and independently check standards proposals.

Additionally, SMEs and project engineers from recent / live DR projects would be required on an

call-off basis to support the work. Whilst the core team would need to be supplier independent to

avoid biasing any one solution, involvement of a broad range of supplier representatives as SMEs is

essential to ensuring robust outputs.

The project team would be accountable for deciding how the standards work and will be delivered

and for managing the schedule of the work such that the standards are available when needed by

projects and the wider industry. This project team could be set up either under DR or within Network

Rail Safety, Technical & Engineering (STE) team. Key will be the agreement of a clear schedule and

targets for the delivery of the standards work that support the DR projects portfolio.

7.3 Output Review This report identifies the standards work required. It needs to be reviewed in conjunction with the

current project portfolio to agree the priorities for the work. The review will also need to consider the

available resources to undertake the work.

7.4 Digital Standards Suite An approach that DR should consider is to produce a suite of “Digital” standards, that include the

changes required to the existing standards suite. This approach was taken for the roll-out of TASS

and allowed the update to impacted standards to be undertaken when there was a major change to

that standard.

Given a large proportion of the changes have been identified to older standards that have not yet

been updated in line with the latest standard policy, this could save significant time and effort that

would be associated with updating and agreeing the impacted standards in the new form.

7.5 Rough order of magnitude estimates of workload

7.5.1 Overview

The following section provide rough order magnitude estimates of the workload involved, at senior /

principal grades, to develop the proposed new standards and prepare proposals for updates to

existing ones. In addition to labour, the project team would need access to SMEs, delivery projects

and RSSB / Network Rail standards owners.

7.5.4 Network Rail company standards

By focusing of developing new standards, rather than updating existing ones, negligible effort is

needed in relation to existing Network Rail standards. Updates for DR would only be carried out as

part of other update work.
