Can you say "pull over" for the bus stopping at the station? Don't you just say "The bus stopped at the station"?
I don't think "The bus pulled over at the station" works.
As far as my response to the original question goes, I would say that a bus either stops or pulls in to a bus stop, and that it pulls into the bus depot/bus station.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
Buses on city streets do indeed "pull over" when they stop to pick up or drop off passengers. If there is sufficient width on the street or an area makred off in front of the stop where no parking is allowed. This allows traffic behind the bus to continue on.
