SD79MAC???

[CShaveRR]

Kind of on this subject, would there be a market, do you think, for an SD69ACE? Something that would have a 12-cylinder engine and produce somewhere around 3000 horsepower?

And...so...I just miss the v12, I think the only accurate unit mentioned, is the SD90H. Back when the Series 710 was first released, I heard EMD actually had a six axle locomotive with a v12, however it was never produced. Between the SD/GP 50, and the SD/GP 60, the reality of the obsolecense of the four axle road switcher precluded any future for anything but...a HP/TE race. Write another Diesel Spotter's Guide?

Tradition has the "9" nomenclature as Series 12VEMD, wheather 567, 645 or 710 class, such as F59PH. Of course the cost advantage of a v12 verses the non-logic of less power, precludes the factor of the SD79AC, or GP79DC. But it is fun to think about! Also, I expect to see nomenclature change again, as Mac, or wide cab is now common, to a more accurate designation, like the SD90H, AC60, Dash9 40DC, SD70sDC, (s-standard cab), SD75DC SD70AC, and so on.

Sorry but if your an ex- RR machinist like me, I needed to know the hp. before they get released from the shop. The onboard computer has a mode that will tell the hp. it is making while in load test. The #'s need to match.

Maybe it should be an SD75-2???

I meant some railroad employees that don't know or give a crap how much HP they have...[:D]

You do realize that those locomotives were designed to have the 4300hp 710 engine removed and have the new 6000hp 265H engine installed. UP needed power ASAP so EMD put the 710 in some units with the intent to bring them in and change them out.

P.S. By the way Zach, I do know the hp. of the units you mentioned. SD-60 3800, SD-70 4000, SD-75 4300. The same rating of the SD-9043. Thank you very much [:D][8D]

I see your logic, but I guess it would be easier for people to remember that it was a 16 cylinder loco with 4,300 horsepower. They already forget how much SD60, SD70M, and SD75s and so on have.

I saw a UP SD9043MAC on the back end of a coal train this morning, and it got me thinking... Since the "43" isn't really part of the designation, and since the engine is not really a "90", shouldn't it be called the SD79MAC?

Here's my logic:
The GP/SD39 has 4 less cylinders (12) than the GP/SD40 (16), same with the 49-50 and 59-60. The SD80MAC has 20 cylinders, so the engine in question, with the same engine as the SD80 but with 16 cylinders, should be the SD79MAC.

Right?

Anybody got any other ideas?
