This paper discusses the design of a centralized control and monitoring system for railway traffic that can be implemented on top of the existing control logic (interlocking system) of Sri Lanka Railways. The overall solution comprises of a central server system and databases with redundancy, Relay House Hardware Unit (with embedded Ethernet and a custom communication protocol for microcontrollers) to interface with the relays of the interlocking system, Dispatchers Controlling Interface for remote monitoring and controlling, and a TCP/IP network which interconnects all the above mentioned components of the total system. The current centralized traffic control (CTC) system in Sri Lanka, loca..
