BaltACD BOB WITHORN September 2015 issue of Railway Age on page 36 is a Progress Rail Services advertizement for an SD70ACe-T4 locomotive featuring an EMD 12 cylinder 1010 engine, AC traction, etc, etc. What gives? Guess I've been in a fog or something, thought they were way behind GE? They are. GE is delivering production T4 engines to multiple carriers as we speak. EMD is projecting 2017 for their T4 locomotive deliveries. Yes, and the prototype they're fielding this year is based on the four-cycle 265H engine, not the aged 710.

Presumably the "1010" is the reworked 265H, based on experience with 300 JT56ACe's in China. Has the same displacement.
First SD70ACe-T4 now exists and is on its way to Minneapolis for the RSIA show. Unfortuneately the locomotive is tarped so no good photographs until the show opens. Routing is NS from Muncie to Chicago, then BNSF to Minneapolis. The large exhibits were on display at BNSF's Northtown Yard in previous shows.
As I think I mentioned earlier, the cylinder heads and the intake ducts look a bit like the C175, which is itself the first big CAT engine with cross flow heads. So the "rework" does appear to make use of years of CAT development of four stroke engines, as well as EMD's experience with locomotive engines and the 265 itself.

GDRMCo According to insiders it'll have a new wide cab, the 4th (well 5th) new wide cab on an EMD since the first SD70.

I'm thinking they'll keep the current wide nose, but rake the windshield area of the cab like the SD70M/MAC. Alot of crews can't stand the current ACe cab even with the isolated option. They should've called the new locomotive,SD45ACe Since it will be rated at 4500HP.
Just found this. Here's the newest EMD ad from the 10/15 issue of RailwayAge.
Here's the link it's on page 56.
I guess EMD's keeping the SD70ACe name for marketing reasons, even though a SD70ACe-T4 has about as much in common with a 710-powered SD70ACe as an ES44AC has with an AC44CW.
I'm sure we'll get a better look in a few hours, but I was able to grab a couple of shots of 1501 here in Minneapolis sans tarp last night: https://flic.kr/p/yst52K
Thank you!
It is really strange that EMD is going back to teardrop windshields. As I recall many of the railroads became sick of finding replacements. The cab is similar to the meter gauge SD70ACes demonstrators built in Brazil. The radiator appears to be a modified SD80ACe radiator, but I can't quite count the radiator fans.
The teardrop windshields really do make a difference in the crew's visibility, especially when the engineer is watching for the conductor to get on or off. Hopefully they've redesigined the cab a bit too, the phase II cab sucks with a tiny desk and nowhere to store all the paperwork. Then again, as long as it's a whispercab I can probably live with whatever else they've thrown in there.
I'm also curious about how it sounds, IIRC the 265 sounded similar to a GEVO with quite a pronounced chugging, which being a 4-stroke makes perfect sense.

Thanks Ottergoose for the pics. I figured that's what the cab would be like.
Here's the official intro from EMD / Progress Rail:
Thanks again for posting the promo. Hmm the castings on the HTCR have took on a European look?! Looks like the exhaust is routed toward the front of the unit. Lets see how this unit performs in tunnels.
SD70ACe-T4 brochure
Interesting that the brochure only talks of 'Individual Axle Control' so presumably this is the end for the traditional 'per truck' EMD traction control.
Also it refers to 'bogies' not 'trucks' - curious for a home-market locomotive brochure.

Never too old to have a happy childhood!
SD70ACe-T4 reveal is online today (4 Oct 2015) on Progress Rail's Youtube channel.
EMD/CAT have a lot riding on this.
I like the new cab on the vision thing.
Some of those workers look like they could lose a few pounds (to keep my healthcare costs down)
Good luck to them. (since I like seeing more than just GE's...)
The new cab is growing on me the more I look at it. Hopefully the units are reliable and sucessful.
The fabricated instead of cast radial truck does still look strange to my eye.
Thereis a brief, but pretty clear, view of the 1010 engine a couple of minutes in.
According to a post to LocoNotes, this locomotive won't have the Whispercab, but the engine and generator will be resiliently mounted. May be interesting to see how that works out.
That is how GE has done it in their locomotives. There has been concern with isolated cabs breaking off of the locomotive frame in crashes, and this is no doubt an attempt to fix this.

EMD has been working on going to an inverter for each traction motor system similiar to General Electric's for several years now.
They built 4 demonstrators so equipped called SD70acE-P6s which were bought by Canadian National and then an order of SD70ACe-P4s (with 4 rather than 6 traction motors in 1-B three axle trucks) for BNSF.

I like the return of the angled windshields.

Wait! It's not a locomotive, it's a "business solution"!

The SD70ACE-T4's cab with the teardrop windows reminds of UP's late phase SD70Ms, which too combined a SD70ACE-style nose with teardrop windows.
Lyon_Wonder I guess EMD's keeping the SD70ACe name for marketing reasons, even though a SD70ACe-T4 has about as much in common with a 710-powered SD70ACe as an ES44AC has with an AC44CW.

The model designation may not be that much of an issue if the owning railroad numbers them in a different series from its other SD70 iterations.
If the company mechanical personnel are looking at the manufacturers model identification of a locomotive to plan their work they area in the wrong line of work. Follow the company's own identification, not the manufacturers. My carrier has 20 years worth of GE AC's that have been recieved in different batches over the years - I am certain each batch received has different details that require different service techniques from their predecessors.

GDRMCoIt'd be rated at 4500hp....
Per the EMD factsheet on the model posted in another reply in this thread the locomotive's power available for traction is 4400 HP. So it's 100 HP less than he SD89MAC (undoubtedly due to engine settings to meet Tier IV) but 100 HP More than the SD70ACe/SD70M-2.
So should the model number SD88Acet-4 or SD71xxxxx?????????? Proof of Cat/Progress/EMD's insidious plot to confuse us poor railfans...
