Anyone done a P2K GP9?
JeffShultz:
I've got two Proto2K GP9 locomotives that I'm looking at installing RailPro on - an LM-3S in one and and LM-3 in the other. I think they have Digitrax DH123's plugged into the factory boards on both. Low end Digitrax decoders at least. Most perfectly speed matched locomotives I own.
Personally, I'd like to keep the factory boards, just from an ease of install standpoint.
So if anyone has done this install, I'm wondering how it does on space - particularly will I have room for an ESU 50321 15x11mm speaker without doing any cutting?
Thanks!

I have a fleet of GP7's that need RailPro installed but they're on the bench awaiting my passenger fleet to be finished first. Hopefully you can get an answer soon.

I think group member gcarter1945 has done a P2K GP9. Hopefully he will share some of his insights.

Jeff, I don't have any Proto 2000 locos myself, but I have seen the internals. If I remember correctly they are mostly weight, right? The Digitrax DH123 is a pretty small decoder. Depending on the size, the Railpro modules might fit without any other work, but I'm not sure about the speaker. Do you have a picture of the inside?
I may be a little over the top here, but I almost always remove all the factory electronics and hardwire in a 9-pin harness. The only time I haven't done that is with a MTH locomotive. There are two reasons why I do this: 1.) less "failure" points....the more connections you have the more likely it is that electrical continuity will be interrupted, and 2.) way more space inside the shell...I don't like to be stressed trying to make everything fit.
The first couple of times you hardwire it can be an exercise in patience. But it quickly becomes routine and doesn't take long.
