My mother asked a person on a train station about a particular car of the train that we were going to board. (Actually in my country each car of the train is named like 1A, 2A etc.) So she was actually asking where our train car would stop.
Where will 2A stop?
Where will 2A come up to?
Which one out of the two sounds better "stop" or "come up to"? I mean what's more likely to be used? (The context is quite clear and the person my mom's talking to knows which train she's talking about)
And about a platform:
Which platform will the train come on?
Which platform will the train arrive on?
Which one sounds better "come on" or "arrive on "?
