Interlocking is the most important component of a signalization system, which ensures safe travel and transportation. An interlocking system helps movement of trains on desired routes in fixed block signaling systems. The first step in the design of interlocking systems is to generate interlocking tables. Generation of interlocking tables for small scaled stations or railway yards can be realized easily. However, when the topology of the station is complicated, generation of the corresponding interlocking table becomes considerably difficult. In this study, a program that automatically generates interlocking tables for a given railway yard is explained. One of the main advantages of the program is that, switches and signal lights are placed automatically for a given station or railway yard depending on the topology.
