Union Station in Cincinnati is a great place to see the vintage architecture as well as some great museums. Among them are a natural history museum, Cincinnati history museum and the ability to go into the old “Tower A” and see the tracks.
If you like trains, then the Cincinnati History Museum is worth the price of the ticket. Home to the largest permanent S-scale train and city set. It is impressive to behold and must be seen in person. It runs on a day/night cycle with 5 minutes of daylight and 2 minutes of night time. The buildings have their own lights, and there is even a house fire that is attended to by firefighters with real smoke!!
Check the schedules and hit Tower A. You will be greeted with knowledgeable train experts and a grand view of the train yard.
