If you find yourself near Milton (FL), not far from I-10 is the West Florida Railroad Museum. This is a great little stop if you have the time. The museum area occupies an old freight and passenger depot that was built in the early 1900s at the site of the original 1882 depot. They have several cars in their collection, including dining cars, flat car, box cars, former Pullman sleeper and two cabooses. They also have a model railroad building, an outdoor scale railroad and gift shop.
The museum is free to the public, but does rely on donations to stay open. It is operated by volunteers so the museum is only open on Fridays and Saturdays. Parking is limited and there is no room to park a RV – so if you go, take the tow!
