Alstom, Consortium Partners Tapped for Toronto’s GO Expansion Project
The multibillion-dollar On-Corridor Works Project will transform collective mobility in the Greater Toronto and Hamilton Area, making it faster, more reliable, and more sustainable.

ONxpress Transportation Partners, a consortium comprising Alstom, Aecon Group Inc., Deutsche Bahn International Operations GmbH, and FCC Construcción S.A., signed the project agreement for the On-Corridor Works Project of the GO Expansion program following a procurement process led by Metrolinx and Infrastructure Ontario.
The multibillion-dollar On-Corridor Works Project will transform collective mobility in the Greater Toronto and Hamilton Area (GTHA), making it faster, more reliable, and more sustainable.
Alstom’s scope within the consortium is anticipated to include the supply of new electric locomotives, train control systems, a new traction power system, and network electrification via an overhead catenary system, as well as the integration of its scope. Alstom will also upgrade the existing GO Transit BiLevel rolling stock, signaling systems, telecommunications systems, and other digital equipment, and maintain the new locomotives and signaling system for a period of 25 years. Alstom’s turnkey approach and integrated offering capitalizes on its global system knowledge and portfolio of solutions to offer state-of-the-art solutions, such as Alstom’s ERTMS train control system, which will be introduced for the first time to the North American market.
GO Expansion will transform the GO rail network from a commuter service into an all-day rapid system, converting the network from a diesel-powered commuter railway to a primarily electric regional express system and will include system-wide upgrades, to deliver all-day service every 15 minutes on the core rail network. The On-Corridor Works Project, Ontario’s largest capital infrastructure project, is an innovative, fully integrated contract that will not only deliver fast, more frequent, and improved rail services within the Greater Toronto and Hamilton Area (GTHA), but also cleaner and more environmentally-friendly service.
The multi-billion-dollar value of the On-Corridor Works Project commences with a safety signaling upgrade work package and a two-year collaborative development phase between ONxpress Transportation Partners and Metrolinx to refine the scope, progress with the design and plan the operational improvements to the system. The scope of work and corresponding contract value will be finalized between ONxpress Transportation Partners and Metrolinx upon completion of the development phase.
The project is expected to generate significant employment opportunities in the GTHA during the design and construction phases. Certified Top Employer in Canada two years in a row, Alstom currently employs over 4,200 employees across the country, including more than 2,300 in Ontario. Hundreds of employees will be recruited by Alstom in the GTHA for the On-Corridor Works Project, including over 300 highly skilled professional and engineering positions to be filled during the first year alone.
