Compatible with any Thomas & Friends track (Track sets sold separately & subject to availability.) Colors and decorations may vary.

Review: Good project - It was perfect for my son 4 years
Review: Perfect for Kids - I got these as a reward for my kid and he thought he was getting a gift because they were “wrapped” in bags, They are great quality and are great for kids. My son has fun playing with them but says that the Percy engine isn’t the right color (he’s blue instead of green). When the package arrived I liked how everything was packaged. The only thing I would say is that it was a little harder to open. Great product!

### ⭐⭐⭐⭐⭐ Surprise Train
*by A***R on January 6, 2025*

This was by far my train obsessed toddlers favorite gift on Christmas. Once he opened it, he was no longer interested in anything else. I do however feel like it is pricey.
