Patent ID: 7328090

Claim:
A method for controlling the sequence of trains during traffic control, with communication taking place between a train controller in a train control center and a locomotive engineer, wherein the train controller transmits movement permission to the locomotive engineer and a movement-permission-specific checking code, which is determined by a train control computer, and the locomotive engineer enters the movement permission and the checking code in a vehicle appliance which uses the same algorithm as the train control computer to calculate the checking code, and compares the calculated checking code with the entered checking code, with the movement permission being confirmed only in the event of a match, and rejection of the movement permission being signaled if there is no match; and wherein the locomotive engineer transmits to the train controller a train running message, which is required in order to release a track section, and a checking code which is determined by the vehicle appliance and is specific to the train running message, and the train controller enters the train running message and the checking code in the train control computer, which uses the same algorithm as the vehicle appliance to calculate the checking code and compares the calculated checking code with the entered checking code, and the track section is released only in the event of a match.
