There was a lot of Train history in here in the Maryland area. Tons of pictures and memories with quite a few areas where the kids are encouraged to touch exhibit pieces. On the third floor there is a massive model train setup that reflects the trains routes in Maryland. There are 5 or 6 running trains going in both directions. A definite must see for train enthusiasts.
It's free to enter and it looks like a privately curated collection so don't forget to leave a donation of appreciation. You can leave it in the jar at the register. They also take donations via credit card for those that don't carry cash.

The train model on the 3rd floor was so cool! There’s a museum on the 1st and 2nd floors. The ladies at the front desk were so nice and friendly. You can get 2 national park stamps here: the Chesapeake and Ohio Canal and the Potomac Heritage stamps. There’s a cute gift shop with train themed things. Plenty of free parking towards the back of the building.

Cute museum. Construction on the outside but nicely decorated on the inside. Impressive model train on the top floor, a gift shop and some interesting items. Free to attend but a donation is recommended. Cheerful staff

Great place to bring a kid who loves trains! If you have a toddler you will need to hold them in order for them to see the model train but it's worth it. They have a simple play area as well with a toy train that my toddler loved.

No cost to visit but donations are welcome. Its a great place to visit for my family with our little ones. They have a huge model train set up to watch. There's also a whole lot of local history info and interesting peices on display for adults to see as well.
