Multiphysics Simulation of a Battery Electric Train Operation

The changeover from diesel driven multiple units to battery electric multiple units is a challenge for operators due
to the limited range of these trains. Therefore, in this paper a tool is developed and described that simulates the
entire operation of a battery electric train. The tool contains a model of the track, the vehicle, the timetable and the
environment. The model of the track is built on elevation profiles, radius information and speed limitation. The
vehicle model is derived from an electric multiple unit suitable for local and commuter train operation. To do
parametric studies or model different train units it is easily possible to change vehicle properties. Modeling the
timetable and the environment allows the simulation of an entire operation day. The overall simulation model was
validated and is consistent. Finally examples show the simulation possibilities and features of the tool.
