This one is quite simple but extremely handy in some cases.
Some coasters of today have two stations at the base of the coaster, one is all the way in the front of the coaster where people get on and usually before a corner you have another one for the passengers to leave (usually used in heavily themed coasters so the cars always appear empty to the guests).
Anyway, construction wise i had a few times the wish to just make two stations so at one people can enter and the other people can exist, otherwise i would always get issue with laying down the path.
