1. A method for operating a rail vehicle network in which a multiplicity of rail vehicles are traveling, the method comprising:
determining with each of the rail vehicles a respective position in the rail vehicle network by creating position information;
transmitting the position information from each of the rail vehicles to a track-side central apparatus;
forwarding the position information from the central apparatus to all of the rail vehicles in the rail vehicle network; and
checking with a rail vehicle-specific collision monitoring apparatus provided in each rail vehicle the position information with regard to a potential collision risk of a collision with one or more other rail vehicles and, when a collision risk is established, generating a collision warning signal;
when the collision risk is established, transmitting the collision warning signal from the respective rail vehicle to the central apparatus;
forwarding the collision warning signal from the central apparatus to at least the rail vehicles concerned by the collision risk; and
sending the collision warning signal within each rail vehicle from the rail vehicle-specific collision monitoring apparatus of the rail vehicle to a brake activation apparatus of the rail vehicle to activate automatic braking of the rail vehicle when the collision risk is established.
