ACR GP7-9

Not done.lol
I'm going to replace the trucks with a set of atlas trucks.
And going to add a power pacK from esu.

I replaced the cracked gears installed new gears cleaned and lubed them.
It runs good on the test track but at a friend's lay out it ran like crap.
It's a DCC layout lots of tight industry switching and I think she keeps shorting out from the truck hitting the frame.

Did you modify anything to create a short like that? Could just be dirty track on your friend's layout...

His gp35 ran fine so under powered dirty track is out.
I did wire both sides of the trucks to the decoder. Motor has been isolated. Not sure what I missed.

I've had locomotives do well on the test track and run poorly on an actual layout. I'd do a really good wheel cleaning, then touch up any exposed wiring or solder with liquid electrical tape...usually deep cleaning and polishing the wheels does it for me. Sometimes there's just enough gunk where the tread meets the flange to cause problems, which would present itself in curves especially.

Atlas trucks sitting under the frames.
Now to adapt the worm shaft to the fly wheel.

Hope this works.

Home made bushings from the atlas trucks to the proto drive.
