Abstract

The paper presents a Matlab/Simulink based simulator of track circuit for urban/suburban transit system. The sub-systems in this simulator includes the Simulink models for running rails, transmitter, receiver, boosting unit, train occupation and termination circuit. All signals in the track circuit can be observed on the computer screen. The parameters for the running rails were measured in field with real carrier frequencies to account for skin effect and eddy currents. To investigate the impact of train position on the receiver signals, the running rail model for a fixed track length is implemented as two variable length track circuits, separ
