Wasp door

I do not understand why they have to use such an elaborate way to indicate that there is a door. Yes, it's really tiresome if something is blocking the door, the train driver then has to get out through the side door.

[ just let the door open inward and the problem is solved... ]

Behind this door are no nuclear weapons, just a train driver...

It would be cool if the door would slide up or down when opening (with a Star Trek like 'Swoooosh' sound). But no, it's a regular hingeing door...
