An ad hoc communication network includes at least one vehicle-side radio device connected to a vehicle, a plurality of track-side radio devices installed on a track of the vehicle, and a monitoring and control unit, which is connected to at least one track-side radio device for communication. The track-side radio devices communicate, without logical connection with other track-side radio devices located within the radio range and with the vehicle-side radio device and forward received data to other track-side radio devices located within the radio range. At least two other track-side radio devices are located in each direction along the track within the radio range of each track-side radio device. The track-side radio devices transfer received data to the closest and to the second closest track-side radio device in at least one direction along the track.

A method and a device for determining a train length of a plurality of coupled railroad traction vehicles, each having a vehicle device with an ID specific to the railroad traction vehicle, include determining the train length of arbitrarily long train sets in a secure and simple signaling manner by having vehicle devices determine if the railroad traction vehicle is coupled on one side or both sides by evaluating coupling contacts. The IDs of all of the coupled railroad traction vehicles or ID pairs indicating adjoining relationships of railroad traction vehicles directly coupled to one another are successively transmitted to a particular vehicle device by digital I/O connections between the vehicle devices. The device determines the train length as a function of received IDs or ID pairs.
