Hello Everyone, I recently changed out the shoes on an old Marklin RE 800 with a pair of the newer style available from Ritters Restoration Germany. Over the years I have converted other older Marklin 800 series locomotives as well as I prefer the old 5100 series track. When I bench test the locomotive it runs great, yet on the track the Pickup shoe is red hot after a couple of laps. I have cleaned the armature and installed new brushes. The loco ran well with the old style shoes made for the 50s solid rail track. Does anyone have any suggestions? Hope you all had a Happy New Year. Regards, George.
