Not Quite Greased Lightning: GO Transit to Electrify, Eventually

Today, Metrolinx released its long-awaited study of GO Transit electrification.  I will comment on this in more detail over the next day or so, but here are preliminary observations while the news is fresh.

Updated 4:30 pm: The study appendices are now available online.  I have not incorporated any information from them in the article below.

The study finds that electrification is a worthwhile venture on selected, well-used corridors, and that it is an important foundation for the growth of GO Transit into its regional role proposed in Metrolinx’ Big Move.

The proposed staging of the electrification project (all times are estimates) is:

  • Preliminary design and Environmental Assessments (3-4 yrs)
  • Union to Pearson Airport, and Union to Mimico (Willowbrook Shops) (4-5 years)
  • Pearson Airport spur to Brampton (Mt. Pleasant) (2 years)
  • Union to Oshawa (including access to a new eastern maintenance shops) (4 years)
  • Mimico to Oakville (2 years)
  • Oakville to Hamilton (James Street Station) (2 years)
  • Oshawa to Bowmanville (2 years)
  • Brampton to Kitchener (2-3 years)

Other corridors were studied, but the best benefit-cost ratio was found to be the combination of Georgetown and Lake Shore.  Events over the next decades may prove this to be short-sighted, but that’s today’s plan.

The implementation is rather leisurely, and if all of its phases take place sequentially, it will be the early 2030s before this scheme is completed.  The Environmental Assessments will use the expedited process most recently seen on the Transit City projects.  This will avoid the need for “alternatives analysis” on projects where the alignment and technology selections are a foregone conclusion, and the “terms of reference” will be much simpler than a full EA.

No individual benefit is cited for electrification, but rather the combined effect of contributions to travel time savings, operating costs, reliability, environmental concerns and long-term capacity of the GO system.
