Where do I find a subway that gives me a private cabin where I can leave my things, and still find them there on the trip back?

Would a private locker at a station, do?

Not really, because then you either have to transfer your belongings from station to station or you have to return to the station with your locker.

I don't really see the difference. You have to return to where your car is parked, too. And you have to transfer your belongings from your car to e.g. your house and so on.
