Modernizing a Maze

Toronto Union Station Rail Corridor which currently contains 35 miles of track, 142 turnouts, 250 switch machines, and 234 signals, combining to yield 4,000 possible routes with a superbly maintained 1928 electro-mechanical interlocker will soon undergo a transformation from electro-mechanical to microprocessor based interlocking control. The replacement will be a state of the art system that will be part of a C$250 million resignaling program to make Toronto Union Station the most operationally advanced passenger terminal on the continent and double its existing capacity when completed. It typifies what interlockings can do, and are doing, for today's railroads and transit systems. Since the bidding has been opened to both North American and European architecture, the project could present a real watershed in interlocking technology. The project involves every part of the infrastructure, trackwork, communications, electrical systems, and passenger areas, and the management consortium's objective is to set out requirements and let the bidder prescribe solutions. That means that both North American and European interlocking architecture are relevant if they can meet GO Transit's needs.
