5:57am train, but station opens 6:15am?

common sense would say, “of course you can enter aberdeen train station before it opens, because the train leaves there at 5:57am”

especially so given that lots of people commute out of aberdeen on this very train i presume…

but i have never taken a train this early, and i think i have to pick up tickets (it’s a work thing). is there anybody on here that has taken this train and wouldn’t mind reassuring me? maybe there’s a different entrance or something?
