Modellistica e simulazione dei Circuiti di Binario.

Track circuits (TC) are special electrical circuits composed in part of the rails of the tracks, Electrical signals are circulated in them by which it is possible to determine the status of free (no rolling stock) or occupied (rolling stock presence) within a controlled portion of track can be determined. They therefore represent a fundamental element of the Control command and Signalling Sub-System (CCS) whose operation has a significant impact on the safety and regularity of railway operations. In this paper, the problem of proper TC modeling and simulation setup for the purposes of the issues of interest to be analyzed will be addressed. The discussion will analyze several case studies of interest for Class B systems referring further ones to subsequent publications. The method presented here, excluding the electrical modeling part of the track, consists of a generic method developed by the author during his experience on the topic. [ABSTRACT FROM AUTHOR]
