>>1034553I would assume that change over won't be immediate so I believe that we will do that and get the remaining years out of the cars and the change over to the newer stock as old units are scraped. Most graphics show pic related as the new stock though this could just be concept and the exact vehicles will be different.
Either way I would wager the guess that since the Stouville and Kitchener lines are set to be the first to be electrified (courtesy of the UPX and SmartTrack) Metrolinx will shift some of the older rolling stock over to those lines during the conversion.
