My son is obsessed with Thomas the Tank Engine trains. His love of trains has even expanded to the NYC subway system. Every time we pass a station, he shouts “COO COO” meaning “Choo Choo” of course. Since I can’t look at another Thomas thing in my house why not get the collection of NYC Subway Trains. They fit right on the Thomas tracks and connect to the cars as well. I think they are way cooler!
