St. Louis Union Station, MO

My first visit here was in 2002 and I found a wonderfully restored station that had been converted into a hotel, retail space and restaurants, and even an aquarium! And there were a few trains parked up on a remaining track or two as part of a museum. I am not sure that this is still there, and at least some of the exhibits are known to have been moved away. But it was a place full of atmosphere and interest.
