Will a shell from and Atlas Trainman GP38-2 fit on an Atlas Master GP40-2? I was looking to do this because I have a chance at getting a sound unit but I would like my Trainman shell on it instead.

I know trainman GP38-2 shells fit Master GP38 chassis and vice versa, I have both and have switched them. I believe I have been told here that the GP40 shell fits both the Trainman GP38-2 and Master GP38 chassis and vice versa. I havent' done it myself but yes I think it fits.

The shell would fit but the question is why would you want a non-turbocharged GP38-2 sound like a turbocharged GP40-2? These two different units really sounded different.

I guess I never thought of the non turbo sound, back to square one, LOL

Well, the Trainman chassis can fit a small speaker above the board, but you would need to replace the fans with see-thru ones to get the sound out.

You can put the shell on an Atlas Master Silver chassis (it will fit the 38, 40, and 40-2 chassis) which has the lead plugs where the speakers should be, and you can install a Tsunami and speakers without modifying the shell.

But, if you really want to go QSI (their decoders sound nothing like the real thing) you CAN get the turbo 645, and adjust the turbo volume to zero. Voila, a redneck non-turbo 645 :D

You can also get the QSI upgrade chip for a non-turbo 645, and put it in the board in place of the turbo 645 chip that's there.

Or you could do the swap and then mute the turbo through the programming of CV's...works fairly well for my Gold series GP38.






Top Five prototypes I'd like to have in HO scale:
1. GP40-2 phase 2c with and without nose headlight, preferably in Master or Genesis format
2. Pullman 3000 cu ft. 2-bay 100-ton cement hopper (Family Lines, CSX,SOU,NS) (Come on, Blaine!! You can do it!)
3. Raceland-built 52'6" Chessie gons
4. Late-phase GP40 in Chessie in Master or Genesis format
5. U36B and/or U33B, preferably in Master format

I think the body shells for an Atlas Master Gold are
totally different because of the dual speakers that are
mounted under the rear of the shell. From what I've seen
the frame is totally different for a "Gold" engine than
all the rest.
One sure way to find out is to call Don at Atlas in Parts.

Since every claims the QSI sound that comes with the Atlas GP40-2 (I have two of them) sound like crap, is it possible to upgrade the chips on those decoders?

How does it sound to you? Mine sounds fine after
I set it to a "Scale Sound level."

I don't have a layout to try them out on right now. Just going by what comments the forum members are saying about the QSI sound. People seem to almost univerally pan the QSI sound while always praising the Tsunami. Are the QSI upgradable?

Well, if you upgrade the QSI chip, you can get slightly clearer versions of the same crappy sounds

They sound nothing like the real thing. The turbo sound is integral to the actual sound of the locomotive. The prime mover sounds nothing like an EMD 645, and the turbo is a whistle. The turbo doesn't whistle in a monotone while the engine is idling!

The frame is the same. The components on top of the frame are different.
