I have the same problem, again a low usage Doodlebug. I think it's an older DC version, Part #: 81456, but I'm not sure. If it's DCC I got a steal! Anyway, the lights come on, but no movement, not even a buzz. I got it at a train show from an old dealer who had a store, but went out of business and was selling all his stuff fairly cheap at the show. He said the Doodlebug spent most of its life on a shelf, never really run. Any advice?
