Im back everybody. I apologize ive been missing in action but just got back home off the road. I now have everything (almost) to attempt to convert my DC GP50 to DCC. I managed to aquire a MRC Prodigy Express  DCC System, 3 used Digitrax DH123 decoders and a airbrush kit (a whole new adventure awaits). Now I just have to aquire the proper tools for the decoder installation and go from there. so hopfully I will have a better update within the week. From the looks of the post, Ive missed quite a bit but with a few days home Ill have time to catch up.

Hello everyone,

     Im in aww that my question has possibly created a new chapter. Not only does it sound like my question has helped others and stirred up new curiosity, but it may have helped a few companys in the process. I wonder how much my checks will be?? just kidding lol.  I hope that this thread has helped others like it has me and it sounds like it has and more. I hope to start or attempt my install(s) soon, just waiting to get the cash cow from the barn and the time to sit down and goin from there. I also wanted to thank everyone who has given advice and input to help me upgrade my fleet. Ill be leaving the thread up to see how far it goes and to refer back to it.

That looks very close to what these have, the biggest diffrence is the circuit board. The ones in myne dont have all the extra stuff, just a plain board with strip of copper down each side of the board with 6 connections. most of the wire colors are on the same side - all red wire connection are on left side of board, black on the. It sounds like you may have found my solution. only one way to find out for sure

Yes they are the newer 8 wheel drive type and are HO Scale. If i can get the pictures smaller than 128kb Ill try to post them. another alternative would be to email them.

Hello again everyone. I have been following the thread and I appreciate all the advice so far. I wanted to express that I understand I have a lot of research to do on my behalf but I also thought I could find out just as quick by asking. With the job I have (truck driver) I dont have a lot of free time to sit down and browse the internet. I havent made the official switch over to DCC yet but when I do, Id like to take my loco's with me. The only use Im looking to get out of DCC is the ablility to have multiple engines running, the ability to turn off/on headlights and maybe a beacon light on top of the cab.I am tempted to do the installs myself its just that I needed to find what parts to get to do the install. If it works it works, if it dont it dont, If i blow one up I'll learn not to do it again lol. I only have the 6 bachmanns and If i can upgrade them and it works than I dont have to worry about re-buying my fleet. I know some of you  probably have quite a few loco's but with what little area id like to model I only need maybe 15 if that. But with this thread and from some of the others I have found information that may help and will try once Im able. Again, Im not wanting to offend anyone at all

Hello everyone.
     Im sure this question is on here somewhere, but. What Ive been tryin to find out is how to convert my HO scale loco's from DC to DCC. I have 6 of Bachmanns Gp50's that Id like to make the switch to DCC with but I have no clue on what to get to make the switch. Any advice or help will be greatly appreciated.
