E stands for "enhanced" Also I'd like to point out that UP didn't specifically spec T4 but the EPA mandates on new production locomotives require tier 4 emissions compliance. These locomotives, both previous and current tier 4 emissions, are still in production with tier 3 compliment models for export only. There is a UP SD70AC-E in preservation in College Station Texas the "bush locomotive #4141"
SD used to stand for Special Duty, however it changed to Standard Duty sometime before the SD70 series started - notice that you don't see any new GP locomotives after the GP60. It used to be that the SD series was a bigger version of an equivalent GP locomotive with more tractive effort, necessitating more axles (hence GP7/SD7, GP9/SD9, GP40/SD40, GP50/SD50, GP60/SD60). GP stood for General Purpose and since the SD series was the same thing but heavier with more pulling force SD stood for Special Duty. There was never a GP70 (could you imagine a 4300hp 4-axle unit?) and there have been no new additions to the GP series since the GP60. If you do see a "new" geep on a railroad it's usually an in-house railroad-specific rebuild from an older GP locomotive that's been reclassified for book keeping. Since the SD70 never had a GP running mate and since demand for any new GP locomotives has dropped off the definition of SD changed from Special Duty to Standard Duty because now the SD70 is the "standard" EMD/Caterpillar locomotive.
Fun fact, UP's entire heritage Diesel Locomotives fleet are SD70ACE! For example, one SD-70ACE is painted in SP daylight paint scheme, numbers 1996 (The year UP bought SP). The remaining heritage locos are also numbered based on the year UP bought the respective Railroads.

The "e" in SD70ACe stands for enhanced. It is improved over the SD70MAC. I always find your videos informative. Keep up the great work.
Love your vids. Broaden your horizons, there's so much more to see out there than just locomotives!

Canadian National actually owns SD70ACes. However they’re extremely rare cause the only have 4 of them. Their numbers are 8100, 8101, 8102, and 8103
2:10 " Its basically an SD70ACe, _but on steroids_ "
That had me laughing for a bit
Nice video btw!
Thanks! Glad I could give you a laugh.
Norfolk Southern is using the SD70Iac.

Correction, one has been preserved so far, the 4141 Bush unit
5:17-5:19: the e in SD70ACe means Enhanced.
The SD70ACe! IS my favorite locomotive!! :D
Same
My O'gauge model railroad power is 90% SD70ACe. And they make damn good switchers at work too. Ps, the e in ACe stands for enhanced.
E for extremely loud cabs
Such a workhorse of a loco. Didn’t know about the T4s and ACu versions!
Beefy, ugly handsome and has a cab rattling issue that EMD didn't somehow notice until CSX and BNSF complained.
64770 Kautzer Hill
These things better be around till the day I die
...8 days then, got it! 😁
@@crsrdash-840b5 huh?
Whats your fav locomotive
ATSF Dash-9 for sure
I love the Dash 8.
Imagine a rebuilt sd70ace
I believe e stands for eco but i could be wrong to.❤ your vids
That's true!
IC LOCO!?!?!?!?!?!?!?
No mention of VTR M-2s, tragic. Nice video anyways
BNSF 9330-9399 are not lead qualified because they are too loud.
That’s why they’re called thundercabs. They were the first ACEs bought by BNSF and are equipped with the high headlight above the cab.
EMD sounds better at run 8
Of course.
e means ECO
SD70ACe is biggest junker ever made by EMD.
Biggest POS locomotive ever made by EMD
The SD70ACE is the absolute worst locomotive I ever had to run.
Why? I don’t understand.
