GP39-2 is a more fuel efficient version of the 38. This looks like the Atlas Trainman. They run very nice in my experience.

| Ok thats what I thought it was, and yes it is an Atlas trainman one, now another question is what DCC chip (8-pin socket) do I need for this unit? its an analogue one at this time, as its DC opperation only (as far as I can tell), so im just trying to figure what I need (want something that I can just plug and play with out having to solder any type of wires to the 8-pin chip) as I want to just do a "plug N' play" set up as far as converting the engine to DCC!!

Jim,
By the looks of it, you have an Atlas GP39-2....The fact that the rear most cooling fans are "2" and are close together is VERY deceiving...As the GP38-2 has the SAME cooling fans roof top, BUT are closer together then that on a GP39-2.....BUT, 2 other spotting features I can see, is the fact your model also has a exhaust silencer, which the GP38-2 didn't have, AND the fact that your model has an Anti-Climber pilot, is the other, as the GP38-2 also didn't have.....
And to go further, the blower housing thats just behind the cab (part that sticks out) on the side closest to us, that has the "rounded" top that goes into a duct, into the walkway, is further away from the cab then the same set up is on a GP38-2, as on the GP38-2, its closer. Very apparent, in the first photo.
Hope this helps!
Atlas, is a GREAT diesel manufacturer!

Jim,
The Atlas GP39-2, needs a 8 pin plug DCC chip that any one of them make with a "Plug N Play" set up, you merely plug any one of them, that are made with the 8 pin plug, for Atlas, as a plug n play and will work!
Listed:
Atlas Trainman GP39-2 Ph1 Plug and Play DP2X or DP5, by TCS....I can't think why it be different then the GP39-2 Phase 2, from the first model....
Hope this helps!

| GP39-2 is like a GP40 without the turbo, makes around 2300 horsepower, it was sold sporadically over about 15 years and has multiple carbody variations as a result.

The GP 39 was a 12 cyl Turbocharged loco. The "39" series was dropped from the EMD catalog in JAN of '72, as customers would rather have the less maintainence of the non turbo GP 38...2 fans and the single turbo stack BEHIND the DB fan, make it a "39".

Ok great, getting some where, what "Plug N' Play" chips are out there? I know this is the 8 pin variety of chip, its the standard DC (analogue) chip in it (if pics will help Ill snap some tomorrow) but I want to know what companies make true PNP chips IE no extra soldering or resoldering of wires, I just want to drop one on the board and boom it has DCC functionality ready to go, I DO NOT mind if I will have to swap chips each time to use it with either DC or DCC (tho I would rather not, and would prefer it be a DC/DCC dual chip thats PNP) but yea I just want to know who makes chips (and that type, or numbers/names) that are true 100% PNP for any 8-pin socket board.
Thanks again guys for the help!!!

I'm confused...if EMD dropped the "39" series in Jan '72, how could there be a Dash 2 variant, since the Dash 2 technology wasn't introduced until '72?

| Technically everything became a dash-2 in 1972. There were plain GP39s and dash-2 GP39s. The latter were ordered new by Reading, D&H, Santa Fe, BN. and I think MKT. Secondhand owners included Gulford, UP, and the Reading units went to D&H then to CSX.
