I had bought the flatcar with tank a couple of months ago. Upon receiving it and putting it on the track, the wheels were so out of gauge on one truck, it couldn't be run. The other truck though better than the first were also out of gauge. I ended up removing the wheels and axles and used wheel and axle sets from Lionel from cars that had similar trucks. This helped tracking immensely. However, an expensive thing to do. Couplers: I removed the knuckle pins and did some filing with a Dremel tool and cleaned that up with a small hand file. This helped the operation of the couplers. For these two reasons, trucks and couplers, I buy very few Menards rolling stock. While I like to tinker with my trains, I don't want to work on every single car that I get. That kind of defeats the purpose of buying inexpensive rolling stock.
