Abstract
Signalling systems are critical in ensuring the safe movement of trains within a
network. The choice of signalling system employed on a particular line has a
direct impact on the journey time and hence the capacity of the line. Computer
simulations provide a viable method for evaluating and analysing the
performance of signalling systems.
This paper describes the development of a multi-train simulator in which five
different signalling systems are simulated on a common section of high-speed
line operating with two trains. The simulator is used to compare train
performance, including differences in journey time and train energy
consumption.
The result shows that, by using more advanced signalling systems and
optimal train control strategies, interactions between trains can be avoided,
thereby improving performance. This also has the effect of reducing the energy
required to make a particular journey.
Keywords: optimal driving strategy, high speed railway; train signalling system,
brute force, genetic algorithm, active set.
