Yesterday the Government of Ontario announced its transit plan and what new lines will be put in. They want to electrify the Lakeshore Line so it can make it faster. I don't think they should, GO Transit doesn't need to have it electrified I don't want any diesel traffic to go away, plus it is a CN Line so it would make it so much harder for them to do construction without affect frieght traffic. SO what do you think?
Electrification of the Lakeshore Line would have its advantages. As mentioned, electric locomotives permit faster acceleration speeding up trip times, especially with the constant stop-and-go that GO trains experience. Electric locomotives last longer with less maintenance costs. Electricity is less expensive than diesel to operate and is generally considered to be more environmentally friendly, depending on the source of the electric power.
There is very little CN freight along the line east of Burlington, so there should be little interference there, if any. The Deux-Montagnes line north of Montreal has been electrified for almost a century without preventing conventional diesel or steam trains to operate there. CN freights continue to use that line today. Assuming overhead catenary would be used for the Lakeshore Line, I believe clearances can be built to allow for overheight cars (like autoracks) and double-stack containers.
