Hi N Scalers, I have an old CC-Kato DL-109 "Rock Island Rocket". I grew up two blocks from a RI mainline and have a liking for these old "Rockets". This has an electrical issue I can't figure out. Sit it on the track and put power to it and directional headlight works, intensity varies with power. But loco does not move. But you take the body off and put 14v DC to the motor and it runs perfectly. It is obviously getting power picked up (light ok) but not getting power to motor (which works fine otherwise). This is one where the large metal weight completely encloses the motor and wiring. I have yet to remove it because I would like to have some idea of what I'm getting in to first. Anyone have experience with these dinosaurs? Thanks. Lowell. P.S. Option #2. Does anyone else make a chassis the DL-109 body will fit on without big mods? Thanks.
