Getting off the train

CTA

There’s this moment after I get off the train, and I’m passing it because I’m walking and it’s stopped, that it starts moving again in the same direction as me, and it takes about one to two seconds for the train to catch up to my speed, but when it does, there are another one to two seconds during which my speed matches the train’s exactly, and I always look forward to this one- to two-second period whenever I get off the train, because here we are strolling alongside each other and neither of us are actually moving at all relative to the other—rather, the ground and walls are zipping back behind us as we float through them, bobbing up and down.
