Ohhh! I like!
If Georgetown electrifies, as Metrolinks has planned, GO might need dual-mode locomotives for the commuter services (unlike the "Express Rail" planned) because I can't see them electrifying all the way to Kitchener/Baden/Stratford any time soon. I know AMT might also be in the market for dual-mode locos for the planned line to the northwest via the Mount-Royal Tunnel.
But they're not Bombardier. Doesn't that disqualify them here?
Yeees, pretty trains, envious.
I could definitely see the Georgetown line electrified to Georgetown and not further for the following reasons:
(I'm a fan of lists tonight, don't know why)
1) Georgetown is the current limit of where a bulk of the people living there commute to and from more built-up areas of the GT(H)A
2) The line past Georgetown switches ownership from CN to the GEXR (Currently owned by RailAmerica). This could cause more complications than its worth.
3) It would be redundant to electrify parts of this corridor while in 20 years time, there would be a straighter, faster high speed rail corridor through the escarpment and glacial river valleys within a close vicinity.
I personally wouldn't see the line electrified to Kitchener until there was a high speed rail proposal on the board. However, Electrification of rail corridors along the Lakeshore and Georgetown will go a long way to helping create true HSR corridors. There's also the benefit communities along the corridor by having less polluting trains running by them on a regular basis.
This also doesn't mean that parts of the GEXR can't be electrified, such as the sections through Kitchener and Guelph. These corridors would likely need electrification regardless. You could begin to see something akin to what's happening in Weston with their rail corridor.
GEXR could eventually see electrification along the north mainline route, but it is definitely at a lower priority than other rail corridor improvements.
[EDIT] @ shontron concerning FRA standards. Yes, it is convoluted.
Even so, we need to start building trains in Ontario again.
