Are an ES44AC and an AC4400CW the same unit? If not, what are the main differances. I know that some railroads may use a differant model # than others. G.E. seams to have become especially difficult. I kinda miss the days when an SD-45 was just an SD-45. It used so be much easier to identify units in the 80's and before. Todays wide cab units all look the same.
Also, did any of the 6000 hp prime movers ever make it into the SD-9043MAC's ? U.P #'s 8239 and 8233 pulled a coal drag through my back yard the other day. When I get a digital camera I'll start getting photo's of these.
The ES in ES44AC/DC means Evolution Series. These units have 12-cylinder engines that are loosely based upon the 16-cyl Deutz engine that was used in the AC6000.
The AC4400 has a 7FDL16 engine.
Looking at the units sideways, the ES has a dual section radiator while the AC4400/-9 is consistent front to back.
No H-engines were retrofitted into the 9043s. UP stuck with the 710s.
I thought the GEVO was a pure GE design. I thought Deutz was taken out back, put out of its misery, buried and the earth salted.
The cabs and trucks are the same... thats it. (even the cabs have different doors) The ENTIRE control system is different (not better but different) the bump you see ahead of the rads on a C45AC are actually air to air charge air coolers to cool the intake air after the Turbo. the C44's and all other toasters and EMD's have water to air charge air cooling systems.
