Idk if this counts as “major work” but at Terminus Panama, they still have paper signs used because it opened early, about a year before the REM:
Here at Panama, under the back paper, it says the door number, in this case “PORTE D” (yes I checked and no one seemed to have notice). At Brossard, they are instead labeled as “AILE B” which is how it should be here too. This means they have a paper sign covering the door number because it’s different from the Aile, and a paper sign in the middle to identify the Aile. All this needs is a simple sticker above the different doors that indicates the Aile number. I don’t know if the ARTM should assume this responsibility, or RTL as they manage the terminal, or REM as they worked on the terminal originally.
This is a brand new terminal so it’s understandable that signage needs to be updated, but I’m guessing this was simply forgotten about and will remain this way unless it’s pointed out more.
