HI: I have a Marklin UP caboose Road # 3721, Marklin # 45702 that has all metal uninsulated wheels and axles. Does any on know where I can get a set of Insulated replacement wheel sets. Thanks
UP,
You can pick up either new trucks or new wheel sets that are insulated. Proto 2000 makes both and in 33". Your LHS should have them in stock. If not, Walthers or M.B. Klein will carry them.
You’ll also want to switch out the couplers and coupler boxes with Kadee #5s or #58s.
