I have an interior for a tram, if someone is in range of the tram and they /enter it, it sets them into an interior, right?

It's not actually an interior, it's just set in a different worldid.

So if the tram moves, will the objects move with it, but not be seen on the outside of the tram and people inside can see outside?

Possible yes, you would create the object that would only be streaming in the chosen WorldID.
Of course attaching it to the vehicle, but then you wouldn't see other players that are not riding the tram.

If you want to see other playes the I would say creat the objects per play. But bad idea
