Hatch Mott MacDonald to help engineer controls for entire GO Transit network

Metrolinx has selected Hatch Mott MacDonald to provide technical consultant services for the re-signalling of the Union Station rail corridor and the provision of a new control system for the entire GO Transit rail network.

Greg Percy, President of GO Transit, the commuter rail division of Metrolinx, said: “We are delighted that HMM will be continuing to provide their engineering services to GO Transit on these complex and critical projects.”

The Union Station Rail Corridor is the 6.4-kilometer hub of this network and consists of a complex arrangement of approach tracks, passenger platforms, and four Interlockings at Cherry Street, Scott Street, John Street, and Bathurst Street. It has 14 station tracks with platform access and more than 180 signals, 250 switch machines, 40 kilometers 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 signaling technology.

GO Transit operates services over 264 route miles and eight rail corridors. Approximately 70% are owned by GO Transit and dispatched by Canadian National Railway and Canadian Pacific Railway from respective control centers. The rail network owned by GO Transit consists of Occupancy Control System (OCS), Centralized Traffic Control (CTC), and Interlocking Operation and will be transferred to a new consolidated control center in Oakville, Ontario.

“HMM has a successful history of working with Metrolinx. We look forward to providing our technical expertise for this major resignaling project,” said HMM president and CEO Nick DeNichilo.
