Analysis, Modelling, and Implementation of Point Contact Reay in Railway Relay Interlocking System

The railway point, a crucial component of the moveable track in the architecture of the railway, is primarily responsible for the hazards of derailment and collision. A railway point is used to divert the train from one track to another track. In the relay interlocking system, the point contact relays play a crucial role. This paper presents the analysis, realization, and implementation of point contact relay in zed board.
