I bought a Rail King A B A unit new from a hobby store in another state before I was finished with my layout. When I used it for the first time it had no power on flat track. I was only pulling a 70 ft passenger combine. I decided to sell the 70ft cars and got new railking cars to match the NYC engines. Still the same problem. I called dealer and he suggested I change the traction tires. I did but no better. I was so disgusted I set it aside and ran other consists. I just now took it to a local MTH Dealer and he said someone oiled it too much so he cleaned everything up and again installed new traction tires and same thing. It won't get out of it's own way. I cleaned track before trying the last time. I''m at a loss. It a 30-20128-1MTH Engine.
Any Ideas?
