    Project Objectives

    Primary Objectives •support economic growth, through enhancing transport links to major employment centres across the West of England

    •deliver a more resilient transport offer, with more attractive & reliable journey times

    •improve accessibility to the rail network with new and re-opened rail stations

    •make a positive contribution to improving quality of life

    Supporting Objectives •contribute to reducing traffic congestion

    •contribute to enhancing the capacity of the local rail network

    •contribute to reducing the overall environmental impact of the transport network.

    Train Service Options

  • Preliminary Business Case • Strong case for intervention, good value for money,

    sound commercial footing, financially affordable and deliverable by 2019.

    • Two train service options both having the same infrastructure requirements.

    • Half hourly service pattern (St.Andrews Road and Severn Beach hourly to fit with MW Phase 2). Symmetrical timetable feasible, giving close to a

    ‘clock face’ pattern.

    • BCR 2.28 to 5.99 and total capital cost including development costs = £58.2m.


  • Preliminary Business Case Capital Costs

    £58.2m capital cost comprises:

    • £2.8m feasibility costs

    • £6.1m preparation costs

    • £49.3m construction costs

    These figures include 30% contingency and allowance for

    future inflation up to and during construction

    Operational Costs

    • Train service subsidy during first 3 years £1.141m to

    £1.765m pa, based on current assumptions – potential to reduce. DfT to pick up subsidy there after until breakeven Point – subject to agreement

    • Also some minor operating costs – bus services, car

    parks etc


  • Preliminary Business Case

    Economic Case We have tested 8 scenarios:

    Timetable –

    Level of


    Number of

    Train Sets

    Scenario 1 5B Baseline 6 train sets

    Scenario 2 5B Baseline 7 train sets

    Scenario 3 6B Baseline 6 train sets

    Scenario 4 6B Baseline 7 train sets

    Scenario 5 5B Enhanced 6 train sets

    Scenario 6 5B Enhanced 7 train sets

    Scenario 7 6B Enhanced 6 train sets

    Scenario 8 6B Enhanced 7 train sets

  • Preliminary Business Case • Assessed operation based on both 6 train sets and 7

    train sets. More work detailed modelling of train paths needed to confirm number of train sets and formations.

    • GRIP2 completed comprising comprehensive deliverables, confirming the engineering feasibility of the project.

    • Early stages of environmental assessment will feed into a full Environmental Impact Assessment

    • Conclusion project feasibility is sound and project should proceed to the next stage of development – Outline Business Case.


  • Preliminary Business Case Funding – Current Position

    Capital Funding - of the £58.2m capital cost, the councils

    collectively need to fund £4.8m. The remaining £53.4m is

    to be funded from the DfT Devolved allocation £44.9m and

    Local Growth Fund £8.5m.

    To date the councils have collectively identified £3.5m of

    the £4.8m, leaving up to £1.3m to find, pending more

    detailed technical work through Outline Business Case.

    Revenue Funding Current Position – train service subsidy

    during first 3 years £1.141m to £1.765m pa, from April

    2019. The Councils now need build this into their financial

    planning so that each council can be in a position to confirm

    its share of revenue funding upon completion of the

    Outline Business Case – Oct 2015.


  • Business Case Stages The Business Case is in 3 stages

    Preliminary Business Case – Sept 2014

    Outline Business Case – Oct 2015

    Full Business Case – Oct 2017

    • Preliminary Business Case is needed for allocation of resources for the development of the project

    • Outline Business Case is undertaken to support statutory processes including the Development Consent Order

    • The Full Business Case follows procurement of construction works and operational arrangements including the train service and confirmation of powers to build and operate.


  • Next Business Case - Outline • GRIP 3 & 4 to be undertaken with Network Rail, which

    essentially in engineering terms is Outline design.

    • Early stages of technical evidence base and public consultation for the Development Consent Order. NB – DCO application to be submitted 4 months after completion of Outline Business Case.

    • More detailed environmental assessment, inc flood risk, ecology, noise, heritage etc for EIA.

    • More detailed technical work on train pathing / train sets, operational costs and demand modelling and revenues.

    • Further progress with GW franchise / procurement of train service (priced option) / DfT Rail on operational arrangements. Including selection of train service option.

    GRIP 3 – Option Selection

    GRIP 4 – Single Option Development

    Portishead Station

    Options Appraisal undertaken early 2014 involved detailed

    assessment of 6 sites, under 3 headings:

    • How each site fits with planning policy,

    • Environmental impact of each site,

    • Deliverability of each site,

    Site options 2A, 2B & 2C identified as

    potentially viable

    Site options 1A, 1B and 3 identified as not viable

    We published the detailed assessment on our website together with the consultation material, it can be down loaded from

    Portishead Station - Regulator

    Office of Rail Regulation (ORR)

    Following earlier engagement with the ORR in 2013, the ORR have recently updated

    their position on a level crossing at Quays Avenue.

    The ORR position is they will consider whether

    there are exceptional circumstances for a level

    crossing subject to the project team providing

    further information in respect of 10 criteria.

    The project team will put together the required

    information over the next two months

    and will then submit to ORR for consideration.

    Powers to Build and Operate

    MW Phase 1 requires a Development Consent Order (DCO), because it’s a nationally significant infrastructure project DCO entails a major planning application and is a 6 stage process that takes up to 3 years DCO work stream will run in parallel with other major work stream such as GRIP and the Business Case, which also require 3 years to complete DCO process includes a requirement for engagement and consultation DCO process requires an Environmental Impact Assessment and Environmental Statement

    Stakeholder Engagement

    Public Consultation in June & July 2014

    was specifically about the location of

    Portishead rail station.

    Response to consultation was very positive

    – 366 people attended the two consultation

    exhibition events and over 400 responses

    submitted to us.

    More Stateholder Engagement Needed

    Wider public consultation will be needed to

    meet the statutory requirements of the

    Development Consent Order process.
