Going through our old "retired" MPC Lionel engines me and my Dad came across this old repainted SD24 and decided it would make a nice "dummy unit to run with our MTH PS2 Conrail

SW9. So we gutted the motor and the electronics from the engine and reworked the headlight so it would only illuminate the lenses in the headlight only and not the cab. We also had to do some touch-up to the paint job. now we are thinking about putting in some LED marker-lights in the engine. Even though this engine isn't perfect to scale and has the stamped handrails I think it makes a great looking engine. Better than sitting in a box under the train layout.

I don't think Lionel ever made a Conrail SD24 - not sure what that is. Maybe a repainted SD20 Lionel did in the later 90s, but that was well after the MPC era, and in any case, the repainting appears extensive (including a different cab no.). Looks very nice.

 

Assuming it was originally a Lionel SD-20, then it would be essentially a scale-size engine, just like Lionel's traditional GP engines are. In your picture, the SW9 appears oversized, but that may be the angle of the shot.

 

You indicated you "gutted the motor." Assuming it was a Pullmor, how did you fill the opening in the frame, and modify the front truck?

this was a engine that we did repaint to Conrail but it was so long ago I can't remember what the original road name was. It was a Pullmor motor and all we had to do was pull off the cap that held the brushes and then removed the commutator. The truck assembly remained in place. The gears and wheels all turn freely.

Do you HAVE to fill in the frame opening? Why can't you just pull out the armature and the carbon filaments from the pullmor motor?

You're right. As he said above, he didn't pull the motor. He notes "It was a Pullmor motor and all we had to do was pull off the cap that held the brushes and then removed the commutator. The truck assembly remained in place. The gears and wheels all turn freely."

 

I've not done this before, but good to know. To make dummies with these traditional engines I've always swapped the shell and just put it on a dummy chassis I got somewhere else. That's less weight to pull around if putting the dummy behind another Pullmor motored engine, but of course that's not a problem if the powered engine is a heavy DC motored job.
