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.

Ex Output:
negative


Ex Input:
Never received item !!! Add-on item missing from delivered package and not discovered after allotted notification time had expired so no recourse as far as a refund. Shop with Amazon almost exclusively and dissappointed to say the least.

Ex Output:
negative

The cans arrived covered in dents and all bent up - It's a miracle they didn't leak all over the box! they were packed in a box with a couple of those useless plastic air bags (basically two quart cans loose bouncing around in a box). Until Amazon improves there method of packing, I will not be ordering these from them again.
