This is a great set for toddler-aged kids. My son is 5 years old and just loves Thomas the Tank Engine, this particular track forms in an oval shape, no straight pieces, and he fits just in the middle so he can play with the train while sitting inside the tracks. You can add tracks, he enjoys building the tracks in different ways and directions from his other sets. My son enjoys it for several hours at a time. It's a great price for what you get, I bought my son's "Lego Thomas Load and Carry Train Set for $31.99" at our local Wallmart.
