Query: Wheels came off taking the cars out of the box

I echo the comments of the other reviewer. The wheels on 3 of the cars came off while taking the train out of its carton. The wheels are not removable which means the cars were rendered unuseable. This item is poorly made. I find it hard to believe that the manufacturer is unaware of this problem. I suggest avoiding this product like the flu.
