After a crash of a yellow subway train with a shunter on the tracks
it is not anymore possible to get the menu inside the driver stand.
This locks the player inside the the driver stand.
Moving the train is still possible, but the situation should IMHO not
After moving the subway train away the menu was again accessable.
After logout and login in the driver stand no HUD is shown (bug #31)
The problem happens when the collisionboxes intersect. The player
escapes the train by interracting with his train, which is no longer
possible when a different train is selected.
I suggest renamming the title to: Unable to exit a train intersecting
with another train
I suggest this sollution: Show the forms when the player clicks ANY
train, not neccessarily the driven train.
