Understanding power supply from a railway operating company's perspective

Abstract

The ability to fully validate the base model in the TRAIN program and the ability to quickly and cheaply iterate the simulations in the TRAIN program to provide technically compliant solutions for each of the five upgrade options meant that London Underground had accurate (and economical) data to feed into their business models. This close working between London Underground and Mott MacDonald enabled the project to remain with the first definition of simulation, 'the use of models and logic tools to test the outcomes of a proposed group of inputs and processes, prior to or in place of their implementation in a live system' without fear that the project would deteriorate into 'an artificial situation or environment'. Rail simulation will continue to play a significant role in the future development of London Underground. The cost and timing advantages are too great to ignore the capabilities of this fine-tuned innovation. Integrated multi-train simulations are the future of railway design. The simulation and optimisation approach also allowed various members of the project team to work towards a common goal the best overall solution from an engineering, procurement and operational perspective.
