Operations and Innovations in the Railway Industry
Introduction Railway development is
undergoing large changes in the
XXI century by …
… interconnecting cities with
High Speed Lines …
… providing people mobility in
towns with Underground
Systems and Trams
For the majority of the,
population, Rolling Stock is
the most evident indication
of this railway innovation
during the last decade …
… with aerodynamic trains
going up to 350 km/h
between cities … even
faster ….
… or driverless trains
moving a large
numbers in towns …
Introduction
… but other innovations have
been required in …
Infrastructure construction
methods
Architecture
Energy supply installations
Signaling
Train safety and automatic
operation of trains
Telecommunications,…

A light structure
In construction works, the module shows its effectiveness
Construction of the entire steel structure in 2 months
Simplicity of construction,
architectural excellence
Success: Central location of Valencia station
Madrid-Valencia, 391 km – 1 h 35 min
The new Valencia station, Joaquin Sorolla, has six platforms that
serve nine tracks–six are of international width
The urbanization of the surrounding area includes the
implementation of ground level parking, a new road, a city square
and its integration within the existing urban neighbour.
Analysis of alignment options2m-MCDA softwareMulti-criteria decision analysis
Poland’s new high-speed network
M-MCDA, multi-criteria analysis design software
Multi-criteria decision analysis is used to help in finding the best
performing alternative when many different criteria of evaluation with
different scales of impact are present
Idom has developed its own implementation of MCDA to obtain a
software that is specially suited for civil engineering
The MCDA method used is MACBETH (Measuring Attractiveness by a
Categorical Based Evaluation Technique)
The software helps in the aggregation of all the information provided by
multidisciplinary inputs.

Software to calculate and design energy supply system4Model REPS
Idom-REPS simulates voltage
and intensity distribution in
railway networks to optimize the
design and position of
transformer substations.
It reduces time to calculate the
energy supply installations,
optimizing the results obtained.

Tunnels. Models to simulate fluids behaviour5Barcelona Metro
Line 9
Barcelona Metro – Line 9
Innovative Approach to Station Design:
Deep tunnels required due to density of
urban environment.
Fire Safety Design very important.
When a fire breaks out in a subway tunnel, the mortal trap tends not to be the fire,
but the smoke. Idom is researching new ways to design these tunnels to prevent
toxic gases from accumulating in the interior of the tunnel.
Simulation Model of train arriving into a
station with a fire in the bogie.Models how the smoke enters the platform and is
distributed in the station.
Knowledge leads to optimum evacuation strategy.
Smoke Streamlines Model in the
vestibule of the Singuerlin Metro Station
Barcelona.This simulation enables us to determine the flow
and pressure of the ventilators that will give rise
to the optimum wind speeds in each scenario
(daily operation and event of a fire)
Fluid Dynamics Model of the same
Station.
Results of the models were finally confirmed
by in situ trails conducted in the station and
tunnel.
Tridimensional models were used to model the behaviour of fire and
smoke in tunnels and stations
Smoke models combined with crowd movement simulation models
to ensure that the smoke and crowd evacuation are coordinated
Models ensure the optimum design of the ventilation for both normal
running and smoke evacuation
Crowd modelling allows the architects to design a more efficient and
safe station
The holistic approach to station modelling ensures that all parts of
the station work together, from the ventilation, to the access controls
and evacuation strategy
Design innovation allows safer and more economical stations

Training simulator for railway infrastructure operator 6For Spanish national railway administrator
(ADIF)
Training Simulator for Railway Operation Control Centre Operators
Developed for Spanish National Railway Administration, Adif, to help
the training of the Control Centre Operator
Benefits for the Railway administration based on:
>Training operators in danger situations with no impact on the infrastructure
>Real against theoretical approach training
Based on a software simulation environment composed of the
following modules:
>Train simulation
>Field element simulation: signals, point machines, track circuits, etc.
>Train control equipment like: interlocking, block systems.
>ERTMS/ETCS simulator
>Virtual actors simulation behaviour with real voice communication with the
student operator like: drivers, maintenance staff, other OCC and station
operators, etc.
Training Simulator for Railway Operation Control Centre Operators
Three different types of exercises:
>Step by step actions for beginners on train control centres
>The student operates a section of the 800 km railway network with 80
station of different types in size and technology, already developed with a
predefined operation plan. The system has the possibility of generating
incidents over the infrastructure equipment and on other trains.
>Collaborative exercises: free exercises for several students, up to 6, in the
same infrastructure with several operators from the OCC and/or local
station operators.
Training Simulator for Railway Operation Control Centre Operators
Open software architecture to permit:
>Creating new stations and new lines
>Importing operation plan from existing networks
>Open communication modules for connecting the system to existing control
centres
>Creating new rules of behaviour and evaluation for each particular
operations regulation of the different railway administrations.
Training Simulator for Railway Operation Control Centre Operators
Configuration for ADIF:
>6 training rooms installed in Spain: Madrid, Barcelona, Valencia, Seville, León
and Miranda.
>Each training room are equipped with 1 teacher and 6 student work stations
>Centralized server for storage and creation of all information concerning
exercises and training itineraries for students.
