Rolling Stock

Infrastructure

Infrastructure, Rolling Stock and Operations.... within Budget and Physical Constraints

Railway Simulation: A Critical Tool

• Understanding Capacity • Interrelated Infrastructure - Operations - Rolling Stock

• High Cost of Improvements

Suite of Analysis Tools OpenTrack Partners’ approach: Use several different tools together in the planning process.

• Viriato - Timetable and service planning • OpenTrack - Operational simulation • OpenTimetable - Schedule analysis (real data)

RailML - Project

• Development of a standard mark-up language (XML) for use in railway applications.

• Objective: Simplify use of multiple applications in railway planning and applications. infrastructure

What is OpenTrack?

• A virtual Railway Laboratory • A Tool to bring the Railway Reality into your Office • A Tool to manage, simulate, evaluate and document your Railway Projects

• A Tool to communicate with your Clients, the Authority, ...

What is simulated?

• All important Processes on a given Railway Network

• Train Movements (Position, Speed, ...) • Behaviour of the Signalling System (Signals, Routes)

• Dispatching of Train Services (Priorities, ...) • Delays, Failures and Incidents

Typical Tasks

• Comparing future Infrastructure Scenarios • Analyzing the Capacity of Lines and Stations • Rolling Stock Studies (e.g. future Rolling Stock) • Timetable Construction, Robustness Analysis • Analyzing various Signalling Systems

Simulation Results

OpenTrack: Advantages

• Easy to use and understand • Accurately simulates railway operations • Wide variety of output formats and data • Can be easily customized for particular user needs • RailML compatibility

OpenTrack: Applications

• Strategic • Tactical • Operational

OpenTrack: Stategic Planning Example Basel Region Evaluation

• Objective: Optimize infrastructure in Basel region to take full advantage of new St. Gotthard Pass Basis Tunnel.

• Analyze: Infrastructure plans and development

scenarios; Operational changes (e.g. train length); Schedule changes.

OpenTrack: Tactical/Operational Planning Example Network Rail Route Modernization (Great Britain)

• Objective: Develop plan for major infrastructure renewal project. • Cross Country Route (Birmingham – Sheffield) • Operations analysis (over 2,000 trains/3 hour period) • Analyze: Impact of track possessions; Optimize work plans for each possessions; Develop contingency plans.
