same thing on the subway, with an extra dimension of starting on the local, switching to the express, then transferring at another station. Pretty quickly you get to know where to stand to get on the most efficient end of the train to be closest to the stairway up to the transfer platform, etc. Makes an otherwise tedious trip somewhat interesting as a puzzle.

And on some systems, one can usually tell if an inbound train is running faster/slower than normal and where to adjust position accordingly to end up at the right door/position/etc..
