A railroad electric power management system includes a service management system, a station management system and a control system. The service management system performs service management of railroad vehicles. The station management system performs operation management of a station facility. The control system controls the service management system and the station management system such that a sum of first electric power consumption and second electric power consumption is to be equal to or less than a certain electric-power regulation value. the first electric power consumption is consumed by the railroad vehicles. The second electric power consumption is consumed by the station facility.

A method is provided for communicating at least one item of information between a first control unit on-board a first vehicle and a public transport network. The information is sent as a command from the first control unit to a first communication unit on board the first vehicle. The first communication unit establishes a transmission link outside the vehicle with a second communication unit connected to a module for executing the command. The second communication unit and the execution module are located on the ground. The first control unit controls the execution module on the ground in a governed slave mode for the command by a master mode of the first control unit.
