Solid State Interlocking (SSI) is the brand name of the first generation processor-based interlocking developed in the 1980s by British Rail's Research Division, GEC-General Signal and Westinghouse Signals Ltd in the UK. It was a forerunner to the modern computer-based interlocking (CBI) systems in widespread use today.
