Such a perfect book for little train lovers. I don’t see any issues with it. My 3 year old son loves to read it every night. The train doesn’t really come off the track, but if I’m holding the book on my lap, I’ll move the book around to help it slide along. It’s bigger than I expected from the pictures, but that was definitely a good thing. So happy with this purchase.

GREAT gift for my 4 year old who loves trains. He got a lot of gifts for Christmas but this one is probably his favorite. It is also easy to take with you if you travel. Fun, entertaining and educational with facts about famous trains. Definitely recommend it!
