Well, looks like you got your wish,
go to www.uprr.com and follow the links to find pics of the real thing!

Once there, click on "General Public", "History and Photos", and "Our Heritage".

For a UP 8309 prototype photo:

All 7 locos are EMD SD70ACe units.

I'm guessing that the WBB 3 rail O-gauge Heritage models will use the "SD90 Scale Diesel" molds as seen in the Williams "Winter 2004-2005 Contemporary Line" fold up poster catalog.  (Wow... almost 18" long, yet still navigates O-31 curves !.... Thats 14.25" radius, folks.  Can you say "Overhang"?)

I'm not an EMD specialist, but there may not be too many visual differences between the two prototypes (SD90 and SD70ACe) ....

Great looking paint schemes, though.... they should sell a ton of 'em.

Hope this helps. 

Sincerely,

The units are based on the SD90 shell are are cataloged as Heritage Units, not as SD70ACE Heritage Units.
The short hood is not correct for the Heritage Units

The major differences (spotting features) are as follows;

The SD90 rear hood is squared off. The SD70 has the standard EMD wedge.
Both model use a flush level dynamic brake fan in the rear.

The SD90 use three radiator fans. The SD70 uses two fans.
Ditto on the radiator sections.

Reference is Diesel Era Magazine
J/A 05 for the UP SD70ACE
S/O 02 for the CP SD90MAC

PS - Remember when Lionel called a geep with a dynamic brake blister as a GP9 and the one without it a GP7?
Things never change.....
