Well the air conditioning is siphoned through the coach, though those little vents you see above the lights on every level.
I think it’s safe to assume air conditioning was also vented into the cab, but couldn’t be controlled separately from the rest of the coach like what was previously mentioned.
I’m glad some schedules are finally out, some of you may have seen this in the GO electrification thread, but here’s a comparison I made between the 2018 Metrolinx FBC for GO Expansion, and the OnCorr development phase schedules from 2023:
This was only directed at people who don’t work on the trains. Engineers conductors and CSA’s are getting transferred over, but managers, supervisors, and other office workers aren’t, so they were told to apply for the same positions at OnXpress before they’re taken by other people.
In the document linked above the positions of where each train will board is marked down. Obviously stuff can change though as OnCorr is still in development
