I was wondering if anyone has ever brought an engine to Aristo at a train show instead of mailing it to them. The engine is only seven months old and still under warranty. It appears to be a bad regulator which took out the circuit board which controls the headlight and marker lights. I was just trying to save shipping charges. I know MTH fixes their o guage trains at york while you wait. This is my first G scale show and don't want to bring the engine if they wouldn't take it.
