This research is to collect data and the design of railway signalling system model to be used as learning media for railway signalling system.The railway signaling system considered as a important system on rail transportation. Since the system is intended to control the trains for safety and on time. We studying of different signal,Detection of position of the train and the technology used in the detection ,Processing systems and Interlocking systems ,The communication and control between Processing systems and trains and include Automatic Trains Control system and Automatic Trains Protection system. We studied data from a textbook, Related research And design of a railway signaling system. That consolidates information from internet ,consulting company and related lecture to be applied to the design of railway signalling system model.
