I've taken the train in Minneapolis from the mall to downtown several times, purely for the novelty of it. We have a lot of freight trains in Iowa. Passenger, not so much.

The lines that goes between the Mall of America, downtown Minneapolis, and St Paul are light rail, and are faster than what would normally be considered a "tram" or "streetcar".
I mainly mentioned it since the parent comment was about a group of girls getting on the train purely for the experience of being on the train, and my experience seemed pretty similar.
Don't know that it terribly matters one way or the other though I guess.
So there are some tram/streetcar/light rail systems out there (like the one in New Orleans) that consist of individual railway vehicles, and are thus not trains.
