Model Railroading > SP 8707 SD40M-2

SP 8707 is a loco that never existed on the SP roster. I call it an SD40M-2 built from an SD45-2. I’ve always like the beastly look of the 45-2 and this one has been on my mind for a while. I numbered it 8707 as it would have been the next number in the 40m-2 series if the SP would have received more MKM rebuilds. The model was an undecorated Athearn with lots of details added, Scalecoat 2 paint, and many decals from Microscale and others. DCC will be added soon.

Really nice! Definitely a plausible foobie.

Very nice work!!!

That's a very well-done diarama, with very realistic track and excellent simulated pavement on the one-lane road.

the 2nd photo is almost too real!!! excellent work!!!

Great subject matter.   SP pretty much had everything except the SD45-2 and SD40-2 from that era.   So it's great to see what it could have been!

 

Looks Awesome & like it was a prototype. I also like the look of a SD45-2 & love the SD40M-2 that have a (SD45 cores) GP40 radiator section.
I always wondered if SD45-2 core were done would they have the radiator fans moved & engine doors changed due to the 3000 HP radiators
Love what you did with the 3 Speed Lettering units.
How about more pictures of them? Especially if Swift Roadrailers are being pulled by them?

There is another imposter in the picture.  I believe SP never had any SD70M-2.  Only SD70M's.
I do like these plausible what ifs.  I have SD50's in EL and U23B's.

SP had lots of SD45-2's, but they all had the "tunnel modification".

Nice model! It does remind me of the 8579, which lost its flares.

Nice work.
Extra points for the ACe.
t4p.

Great-looking trio in pic 2! Will you put a sound decoder in?

Well Done Concept. BEAUTIFULLY detailed. Defintely plausable. I would have LOVED to have seen the SD45-2 in UP colors. A patched SP unit would be a close second. I love it when modelers think outdise the box. (no pun intended)
