I’m just looking at the floor plan of McGill REM station that I found, and I noticed the space for the fare machines appear way smaller and a different shape from what the fare machines are like currently:
This might be just the architectural plans making a shape to show the general idea of where they’d go, but I hope it’s a hint
Also, while this is an older floor plan, at Du Quartier, there seems to be possibly a fare machine located on the inside of the system, possibly hinting at tap to exit?
