Yesterday we came across a high speed moving walkway linking two platforms that are far appart in Montparnasse Bienvenue. The cool thing is that it goes at 9.9 km/h. and to get onto it there is this short ramp that accelerates you up to speed. The way the accelerating ramp works is really cool. its a sereis of small rollers, each going slightly faster, so you just stand there and get accelerated by these rollers, towards the moving walkway proper. The rollers felt a bit weird, like we were losing our balance, but I’m sure once you do it a few times you’d get used to it.
