Development of an Electronic Simulator for Relay Interlocking (ESRI)

Railway interlockings represent the systems on which the safety of all people using the railways depends on. Legacy systems, especially relay based interlockings, persist on the railway network and are foreseen to remain in operation in the long term. This paper presents the development of an electronic simulator of relay interlocking designed to be used for the training of future engineers. The system reproduces the functions of a typical Romanian relay interlocking. The simulation software was developed in LabVIEW, while hardware development involved the design of special interfaces with a traditional mosaic control panel and a scale railway model.
