Abstract
A railway system with at least one track having at least two rails and a method for encoding data for this railway system are disclosed. Railway signaling systems are located proximate to the tract for controlling railway cars moving along the rails. The railway system also includes safety systems associated with the railway signaling systems for exchanging data between the safety systems for safely controlling the railway signaling systems. The data are exchanged bidirectionally by signal pulses, whereby digital electrical signals are transmitted via the two electrically conducting rails. For encoding the data, each data point is formed from one or more signal pulses within a predetermined cycle time which is divided into time intervals. The encoding capacity can be enhanced, without significantly increasing the complexity, by using electrical signals that contain the encoded data in each time interval in form of at least one of three different signal states.
