Abstract: A method for moving a line of vehicles, which has at least a first vehicle and a second vehicle permanently and directly following the first vehicle, includes moving the vehicles at a specifiable, constant distance to each other along a route on the basis of a specifiable overall operating strategy which is assigned to the line of vehicles. For each vehicle of the line of vehicles, a respective individual operating strategy is specified depending on a route profile lying ahead, where the individual operating strategies differ from one another. As part of the overall operating strategy, the distance between the vehicles is increased before the line of vehicles reaches the route profile and each vehicle is moved along the route profile on the basis of the respective individual operating strategy. The line of vehicles is moved on the basis of the overall operating strategy after passing through the route profile.
