So I have a mth railkind burlington route diesel passenger set. The engine will not move, next I see a plug under the back coupler but don't see any plugs on any of the cars to plug into it. The engine has sound, bell, whistle, etc.. went through the reset procedure and still nothing. However, if I plug it into a dc transformer, it runs fine, forward and reverse. However, If you put the dc transformer in forward, the loco runs forward all the time, if you turn the transformer off and back on, it still runs forward. Any other ac engine reverses every time you turn the transformer off. Any ideas?
