Energy-efficient optimization for train tracking operation in urban rail transit

This paper investigates energy-efficient operation for two tracking trains. The operation status of the leading train are combined into the optimization of operation for the following train. In this case, the energy-efficient tracking scenarios are studied and a new switching optimization thought for energy-efficient train tracking operation is proposed based on tracking scenarios analysis. Then by improving the energy-efficient operation optimization method for single train, the energy-efficient optimization method for train tracking operation is developed and analyzed. Simulation results show the feasibility and effectiveness of the new method.
