Unless, you are a history buff and would like to find some cool facts about FDR, taking a kid to this park will probably be a must. Kids and trains go hand in hand. We started taking our son here way before he turned a year old and we ended up having his 1st birthday party here. There is the train and the caroseul and a cool little place to get ice cream and toy trains. I really do like it for parties or picnics because the park is large enough to accomodate extras such as a petting zoo or inflatable bounce houses.
If you like history, you have to check out the railroad cars set up. One is the actual Presidential car that FDR used and the tour guides there can provide a lot of insider information on the life of FDR. The first time I visited the train park, I think I spend most of my time speaking to one of the guide. Very interesting!
