Our two year old loves trains and going to this place feels like a vacation because he is so entirely entertained. The facility is beautifully restored and they've put so much entertainment in for kids that I don't think he'll ever tire of visiting. Whenever we visit family in Maryland we head here. They have a very large play area in the main building that includes multiple train tables, coloring areas and a dress up area (as well as comfy ricking chairs for mom and dad.) There are also a number of restored trains kids can walk in and lots of fun buttons to push. Outside there are more trains to walk through, a model train set up (big hit with kids) as well as small rides for kids and picnic tables. There is also a restored train trip you can take from the museum which lasts less than an hour which is a prefect time frame to maintain the attention of young ones. Just when you think you've seen it all there is a second building with more trains the kids can walk through.
