Trapeze Rail System – Timetable Robustness Analyser

Analysis of train timetables to predict resilience to delay

Timetable planners are being asked to identify additional capacity in an already congested infrastructure to meet the commercial pressures of increasing demand for rail services. Train operating companies are also increasingly being required to improve reliability, and  may be penalised for late running trains. No railway timetable ever operates perfectly, and delays in operation can be both costly and damaging to the image of the railway. Many delays are avoidable either through more efficient despatching of trains or through better  planning to provide a more resilient timetable. However, quantitative analysis of timetable robustness has in the past been almost impossible, so timetable development has relied on experience and local knowledge to maximise service reliability.

Trapeze solution

Trapeze Group Rail has developed a powerful new tool to help railway operators to identify avoidable timetable problems, and to be able to do this long before they become visible on the day of operation. Based upon an existing timetable plan and requiring minimal additional information, the Timetable Robustness Analyser (TTRA) can rapidly pinpoint problem trains and locations. This then allows corrective action to be considered well in advance, and the effects – both costs and benefits – of alternative courses of action to be evaluated. Such action may involve changes to the timetable and resource schedules, changes to the infrastructure, changes in train regulation guidelines, or a combination of these factors.

In brief

  • TTRA is used in conjunction with a timetable planning system to measure the resilience of a timetable to everyday minor disruptions.
  • It simulates multiple days of operation of a timetable by applying either pre-planned (e.g. temporary speed restrictions) or random delays and monitors the propagated delays which result.
  • Used as a tool in strategic planning, it can help improve the cost-effectiveness of infrastructure alterations.
  • Used as a tool in both long-term and short-term planning, it can significantly improve the quality and reliability of the timetable, thus avoiding costly problems in actual operations.
  • TTRA has been used to analyse networks in the UK, Norway and Sweden, and been shown to predict service performance with a high degree of accuracy.
