We were very disappointed with this product and plan to return it. Neither of us is a train hobbyist; we purchased this to put on a table top around a small Christmas tree. Parts were broken, misaligned, and did not easily 'push' together. The notes below detail these issues. 1. One of the linkage bars on the train engine was not attached to the main drive wheel and just flopped around. Since the bar wasn't necessary I decided to tape it to the side of the engine and see how the train operated. 2. The coupler height between the coal tender and the passenger cars was mismatched to the point that the car would become disconnected whenever the train would go into a curve. I tried each car but they were all the same. 3. The track didn't just 'snap' together. It was necessary to slightly wiggle and twist the track when pushing it together so the small metal clips engaged with the metal part of the track. In several cased I had to use the tip of a knife to lift the metal clip up into place while pushing everything together.

This was my child's favorite toy she got for Christmas... for 3 weeks. Then it broke in half. She is 3.5 and a confident walker, so this is not an issue of undue pressure on the cart. The legs snapped in half. Same spot and issue as almost every other complaint. It is not worth the money saved when it is only used for 3 weeks. Either don't get a shopping cart or splurge on a better quality one. Just don't waste your money on this one!
