Abstract :
This paper describes the dependability evaluation of track circuit receiver. The device is a component of railway interlocking system used in Czech Republic at conventional lines. The device is based on 2oo3 principle for high dependability. The reliability analysis, model and safety characteristics calculations of this device are described. Markov chain model is used for the reliability analysis.
