Modular system for the monitoring of railway signaling equipment

This paper presents a modular system designed to solve some specific problems on the monitoring of railway signaling equipment. The addressed problems arose from the needs presented by Trenes Argentinos, the company which operates almost all passenger rail transport in Argentina. The developed solution is examined, consisting of an embedded system with its hardware and firmware architecture along with server-side software that stores, processes, and displays railway signaling status to authenticated remote users. Obtained results are discussed and specifications compared with equivalent systems to highlight contributions in this field.
