Just back from Steamtown in Scranton PA. Stunning, as is the marble/tile lobby of the nearby Lackawanna depot, now the Radisson. Steamtown is part of the National Park system and free to enter. If you only have 15 minutes, spend it with the newly painted (last year) Big Boy 4012 in the parking lot. A tiny sign says you can't climb on it, but there are no ropes so you can touch whatever you can reach. It's like three stories high! 
If you have 30 minutes, Big Boy + inside the Roundhouse. (Actually inside, not just the turntable). But you should take several hours as all the exhibits are well done. Plus, starting this week, the steam train and trolley rides are going around the area. No one was there on a weekday afternoon and no guards are telling you not to touch things, but park rangers are there to answer questions.
