Query: Great fun

This was a great choice for our recent travel by plane for our 2 1/2 yr old twin boys. It kept them busy for quite some time and they loved all the different choices of Thomas characters to play with. The only drawbacks were that it was pretty heavy and too big to fit in their travel backpacks, so Mom got to lug them around. Other than that, the pieces can tear apart relatively easily, with the paper front pulling away from the magnetic backing... not a very durable toy, but fun nonetheless. Also, shipping was super fast - two days!
