Hello, I finally have the new layout at a point where I can run a complete loop while finishing the rest of the track work. All my power runs well on the track, (diesel and steam) and through the turnouts EXCEPT my two Mikado's. They stop at exactly the same places on the layout and spin their drivers. I have checked the track and the units for guage etc. No problems that I can see. Anyone having or had this problem with their Makado?
