Proto 2000 GP7
« on: March 18, 2020, 10:28:01 PM »
Is it possible to install a LM-3S in a Proto 2000 GP7?  I think there may not be enough room.

Boomer68:

I have a sizable fleet of the P2K GP7/9/18's and will one day get around to getting them RP configured. I know with 100% certainty that I'll need to mill the weight to install a LM, a PBM, and a speaker. It's these locomotives that will force me to invest in the proper milling equipment. At some point in the future I plan to offer core exchanges for milled P2K GP weights.

Old post I know, but - to the subject I am curious about.

Proto GP7s, GP9s, GP18s GP38s ..... I own quite a few of them and hoping the installs were not too terrible ?

I like Jacob expect to do some milling and cutting. Definitely looking into a drill press with milling bits. I have used a bench grinder in the past
fixing the old Proto GP38s. They are prone to zinc rot chassis syndrome. I just put an Atlas chassis in place and adjust the weights a bit, cut shell tubes .... works well.

Anyway - how did the GP7/9 installs go ? Please elaborate tips and details.
I am sure HO installs in general will require some cutting to make room, just what to expect ?

Thanks

Pat;

For full disclosure, I've abandoned RailPro and went back to DCC using ESU LokSound. I'm got tired of having to reinvent the wheel every time I wanted to run a locomotive. Good luck to you if you decide to mill frames.
