Help! I’m new to engine maintenance. I have an N scale Kato EMD GP50. It runs for about a minute or two, but then the wheels spin and it won’t pull anything. It’s still getting power, of course, 'cause it’s spinning in place and the lights are on. Any suggestions?
most likely on of the gears vibrates off. try taking apart the trucks and putting the cear on coorectly (if you do it right you can super glue it) Tim
