I installed 28" wheels on most of these then splashed the wheel sockets with graphite. There are still 12 of them with 33" wheels. The wheels rub on the bottom of some of the chassis kind of acting as brakes and causing a drag on the train. They roll much better now. The next problem was the coupler heights. Quite a bit of variance between makes of the models. Lots of shims and now they are all spot on.
