A railway system and a method for forwarding data in a railway system are described. Railway signaling devices are arranged near the rails. Other devices associated with the railway signaling devices each have a unique identifier, with two adjacent devices exchanging signals with one another via the rails. To transmit information in addition to the data for safely controlling the railway signaling devices without reducing the transmission capacity for the data for the safe control, a portion of the data can include the identifier of the origination device, the information and the identifier of the target device. When these data are forwarded, a first device transmits the data to the immediately following second device in the direction of the target device. The second device receives and stores the data, and returns the data to the first device, which then compares the returned data with the initially transmitted data and acknowledges to the second device the identity between the data.
