GO Train

Projects Status Update

In December 2010, Metrolinx completed the Electrification Study which investigated the implications of electrifying the GO Train network. Based on the findings from the Study, the decision was made to commence the preliminary design and engineering of the power supply and distribution for the Georgetown and Lakeshore corridors and the undertake the environmental assessment for Phase 1: the Air Rail Link (ARL) from Union Station to Pearson Airport.

For the EA to evaluate the electrification of the ARL service, the Transit Project Assessment Process (or TPAP) will be used.

The EA will look at possible impacts (both negative and positive) associated with converting the ARL from a diesel to electric operation.

Following a competitive review process, a consultant contract for the preliminary design and environmental assessment (EA) for the electrification of the ARL was chosen. The contract was awarded to Parsons Brinckerhoff, a global consulting firm with expertise in the planning, development, design, construction, operation and maintenance of electrification infrastructure construction and management.


Project Background

Electrification Study: Findings and Final Report

On May 26, 2009, Metrolinx announced that it would be undertaking a one-year study on the feasibility of electrification of the entire GO rail system. In comparison to other similar studies, this study was unique as it examined the entire GO rail system. It was comprehensive in its approach and addressed the impact of different technologies at a high level of detail. The Study considered the economic, social, environmental, health, and technological factors for current and future diesel and electric technologies. The study was completed in December 2010.

On January 19, 2011, Metrolinx released the findings of its comprehensive study on the electrification of the entire GO Transit rail system and the future Air Rail Link (ARL), as a future alternative to Tier-4 diesel trains.

After a careful review of the findings, the staff recommended to the Metrolinx Board of Directors to proceed with the electrification of the GO Georgetown and Lakeshore corridors in phases, beginning with the ARL on the Georgetown corridor. At its Board meeting on January 26, 2011, the Metrolinx Board of Directors approved the staff recommendation. The Province of Ontario, through the Ministry of Transportation, supported the commencement of the preliminary design and engineering of the power supply and distribution for the Georgetown and Lakeshore corridors and the environmental assessment for Phase 1: the Air Rail Link from Union Station to Pearson Airport.

Reference Materials

Shortly after Metrolinx announced that it would undertake a comprehensive study of the electrification of the entire GO Transit rail system, the Metrolinx Board of Directors established a Community Advisory Committee (CAC) to assist in developing the Terms of Reference for the study.

The CAC provided substantive advice to Metrolinx, helping to shape the Terms of Reference for the Electrification Study. The CAC, whose mandate was complete once the Terms of Reference were developed, consisted of a diverse group of transit and engineering experts, community leaders, GO Transit riders, and urban planners. Members of the former CAC have been invited to continue their participation as the Electrification Study continues.


The Big Move


Union Station rendering

In late 2008, Metrolinx published a Regional Transportation Plan The Big Move a multimodal vision for regional transportation to strengthen the economic, social and environmental sustainability of the Greater Toronto and Hamilton Area. The Big Move sets out a fast, frequent and expanded regional rapid transit network as a key element of the plan. The plan includes establishing Express Rail and Regional Rail services at speeds and frequencies that could be enhanced by system electrification.
