The Union Station rail corridor is the 6.4-kilometre hub of Toronto’s transit network and consists of a complex arrangement of approach tracks, passenger platforms, and four interlockings at Cherry, Scott, John, and Bathurst streets. The corridor supports GO Transit commuter trains, Canadian Pacific, Canadian National, VIA, and ON Rail operations. It has 14 station tracks with platform access and more than 180 signals, 250 switch machines, 40 kilometres of circuited track, and all associated infrastructure, dating back to the late 1920s. This will be replaced with state-of-the-art computer-based interlockings and LED signalling technology. The scope of work has included track additions and upgrading, replacement of all special trackwork in the multi-track rail corridor extending almost 6.5 kilometres east and west of the station, and replacement of the 90-year old signalling system with new state-of-the-art signals, communications, power supply, CCTV, and SCADA systems. The program is expected to wrap up in 2019.
