Jean Drapeau was cutting the ribbon underground in 1966, and what he'd been handed was a string of rooms by different architects, a new one each time the doors opened. You go down one staircase into bare poured concrete and up another into coloured glass. Every one of those tiles was set by somebody's hand, and the vaults were poured by men working in the dark under a working city.
Fabien, Marcelle Ferron's glass went in at Champ-de-Mars two years after that ribbon, and it works like a lighting rig — the sun moves and the colour crawls across the platform and the people standing on it. Any lighting designer would take that gear in a second.
Fabien, the trains run on rubber tyres on concrete rollways, so it's a quieter ride than you expect under all that concrete. Twenty-six stations open that year, and Expo 67 about eight months off — they built it knowing the crowds were already on the calendar.
