I have 2 sets of Williams Passenger Cars that have never rolled well .....even right out of the box. One set is a 5 car SP aluminum set with 2 add-ons from the late 1980's to early 1990's and the other is 6 car GN Madison set which is a few years newer. I noticed the wheels weren't made to turn on the axles as with Lionel trucks. Help with lubricants is marginal at best. My healthy Lionel GS-2 barely pulls 4 cars. Has anyone experienced similar difficulty? Does anyone have some suggestions other than replacing all of the trucks?
Thanks
Chris
