There are at least some in the Paris subway, including one that went at 12 km/h but was decommissioned in 2011: https://en.wikipedia.org/wiki/Moving_walkway#Tr

  Man, they should've designed it similarly to the video, with parallel tracks with differing speeds. But people's lack of attention would probably lead them to park a foot on each track and causing a tumble. Speaking of speed, in the Stockholm main station the escalators go faster than others I've experienced... But I don't know if they've adjusted the speed since my experience years ago.

  That one was in activity about the same period I took the Montparnasse station somewhat regularly, and over those years I couldn't ever take it as it was always either broken or running opposite to my direction. I do think a concept with parallel tracks moving at different speeds would have been easier to use and more reliable though. But it might not have been revolutionary/over-engineered enough to attract attention and subsidies.

  Decomissioned but still rolling, just slower.
