Train drivers receive information about maximum permitted speeds, speed limits further along the line, and upcoming objects such as signals, signs, level crossings, and points. The information is displayed on a panel in the driver's cab. Prior to a new target point, the driver receives information to help him brake effectively. The ATC also warns the driver when the maximum permitted speed has been exceeded, and activates the brakes automatically if there is any risk. Interlockings supervise and control wayside objects in such a manner that trains can run safely.
Signals guide the traffic and provide route information by using different lamps and colours.
Point machines are used for switching points, while the automatic block system indicates the position of trains on lines between stations. Balises and encoded track circuits are positioned in the track and convey information to trains, intermittently or continuously. Its projects cover everything from technical feasibility studies to installation and commissioning. Before the Computerised Interlocking System allows a signal aspect to display green, it checks that the train's route is clear of trains and that all points are locked in the correct positions. Adtranz Signal supplies a wide range of wayside equipment, including signals, sleeper-integrated point machines, automatic block systems, balises, encoded track circuits and level crossing protection.
