@Lou1985 posted:I have a MTH Premier FEF. The locomotive will do 054 no problem. The tender on the other hand not so much. It'll do 054 going forward running slow. Fast speeds (40 scale mph and up) or reverse and the "centipede" wheels jump the track.
These UP tenders as well as the similar NYC PT tenders have limited side to side play in the wheelsets. That can be increased for more play by machining the axle bushings thrust face.
