Railway stations
Typical applications in railway stations may include train control, interlock, train surveillance, train
radio and train information. One of the main tasks of railway stations is the interlocking which is the
central function to ensure that trains move safely. For interlocking, RSTT obtain information about
track occupancy and the position of movable track elements.
