I just purchased an aluminum Williams Pennsylvania Passenger car set. The cars are the 15" length that would take my 042 curves. when I run the Congressional set that has the fast angle wheels, they glide right over the switches (Ross and Gargraves). Trouble is that the Williams with the old fashioned wheels spinning on axles seem to catch and derail on the switches about 50% of the time.
I would like to change over to the fast angle wheels with the needle bearing axle ends. Does anyone know if the fast angle wheel sets will fit the Williams trucks?
