Signalling Systems

TSTS provides indoor and outdoor interlocking systems for small and major stations. Since we began operations, within short period of 7 years, we have completed more than 265 stations commissioning. We can provide both centralized and distributed interlocking to suit the requirements of Railways.

Our electronic interlocking system is based on proven EI system K5BMC from Kyosan Electric Mfg Company, Japan. K5BMC is a hot standby system with 2 out of 2 hardware and diverse software. It is a SIL4 certified system as per CENELEC terminology. Its I/O controller can be used as object controller (OC) and hence, use of copper cables can be minimised. Using an object controller has its advantages which include reduced complexity of the system, cost effectiveness, and component’s reuse.
