Energy-saving automatic optimisation of train speed commands using direct search techniques

This paper describes two computer tools that have been developed for the automatic optimisation of train speed commands. Given a target time for the trip between two consecutive stations, energy consumption is minimised. Two driving strategies have been considered, one based on coasting-remoter cycles and the other in space-related traction commands. Direct search techniques have been applied, using simulation processes that include detailed models of the train and the line.
