  • 1. Simulation systems for training, validating and design optimisation – a traffic management case study Tim Gray 29th April 2014
  • 2. Content • Introduction • TRE & Hitachi • Evolution of signaller training • High fidelity training simulators • Signalling and operations design validation • Next generation Traffic Management requirements • Project and operational risk reduction • Conclusions 2
  • 3. Introduction to TRE & Hitachi • TRE background • Work in Scandinavia • Hitachi acquisition • Hitachi activity in Europe • UK Scenario and challenges • Application to Scandinavia 3
  • 4. Evolution of signaller training (1) 4 • Use of model railways and layouts • Training by ‘shadowing’ experienced staff • Heavy focus on knowledge of “The Rule Book”
  • 5. Evolution of signaller training (2) 5 • Mandated in UK following Ladbroke Grove • Training, assessment, competence check • High fidelity is important • 100% replica, safe off-line environment • Practice response to disruption/emergency • c.140 TREsims now installed in NR • > 90% of VDU signalling systems simulated • Multi-vendor Product Acceptance granted • Accurate model of interlocking • Modelling and decision support….

  • 13. Validation, Design & Optimisation In Addition to Training and Competence Management; • Design verification – new/upgrade schemes – infrastructure layout – signalling – operations • Construction programme evaluation • Timetable testing • Service reliability & performance analysis • For mainline and depot infrastructure • In fact, simulate throughout the life cycle 13

  • 15. Case Study - Traffic Management System • NR implementing a UK national Traffic Management System • Key benefits • NR plan first deployment, then roll out in ROCs • Three prototype suppliers • TREsim used to evaluate • Joined existing simulations • Virtual area test bed • 4 workstation areas/24hr timetable/c.1600 trains 15
  • 16. Tranista Hitachi’s Traffic Management System • Based on over 40 years experience in operation • Continued development, in collaboration with users • 100% Automatic Route Setting, with no manual route setting interface on some Japanese systems • Can be customised to provide the “look and feel” required by different railway administrations • Strong desire to implement in Europe • Positive feedback from trials in model office 16
  • 17. Tranista Model Office 17
  • 18. Tranista for Network Rail • Provide “One Version of the Truth” to all users • Has the ability to control anything from anywhere • Routes all trains according to the plan: – Conflict detection and resolution – Short-term changes to the plan – Long-term changes to the plan – Stock & crew allocation • Can work with existing/legacy control systems • Demonstrated using real data from the Leeds area – Over 1560 trains per day (Inter-City, Commuter and Freight) – 35 Stations 18
  • 19. Tranista for Network Rail 19
  • 20. Benefits (1) • Extensively tested by NR operators, controllers and TOC staff during the evaluation period. • Successfully performed wide range of operational scenarios. • Worked well with the simulated railway environment • De-risking real railway implementation • Well-received by the evaluation teams. – Initially some resistance to the “everything according to the plan” interface, as operators were used to setting routes, but this was soon overcome. • Consistently delivered high levels of performance • and enabled pro-active action to address operational problems and recover the timetable. 20
  • 21. Benefits (2) 21 • Use of simulation as part of the Traffic Management System evaluation was well received • Enabled extensive project de-risking and stakeholder engagement • Can demonstrate performance aspects of the TMS • Will be used in first deployment projects for similar validation prior to roll out • Then an on-going tool for operator training, competence management, scenario modelling • And future changes to infrastructure and operations
  • 22. Summary • Signaller/dispatcher training is a positive benefit to performance and safety • High fidelity simulation allows normal and extreme situations to be modelled and trained • Positive project and programme benefits via early modelling • Staff and system readiness can be evaluated prior to live use • Traffic Management Systems bring enhanced timetable delivery and many other benefits • Use of simulation in TMS (and other) projects is encouraged • To yield positive reduction in project, implementation and operational risk • Please speak to TRE and Hitachi colleagues in the audience. 22
