And if you look at the front of a train when it's stopped, you can plainly see that the floor-level begins a third of the way up.

You're never at that angle, though. When you see the train, it's either moving, or you're about to get on it.

It's still stupid, for all the reasons you mentioned, but inside it's hard NOT to think of the floor as being the bottom of the train, in the same way that a deep lake only goes up to the middle of the ducks.
