Abstract

In general, there are three complementary approaches to energy reduction in urban rail systems operation, such as rapid rail or metro. Firstly, the driving style and timetable of a single train run can be adjusted, so that traction energy consumption is minimal. To implement this strategy in manually operated systems an assistance system would be necessary. Secondly, the use of energy regenerated during braking in the railway network contributes to a further reduction of overall energy consumption. To influence the amount of regenerative energy used by other trains, the optimal choice of the synchronization time between the departures in the two directions is necessary as well as train running time control. The third approach presented deals with strict adaptation of transport supply
