SD70ACe-T4 - does EMD actually have a T4 locomotive?

Here's the official intro from EMD / Progress Rail:

 

3 mins 42 seconds of all the buzz words you can apply.

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.

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.

Thanks Ottergoose for the pics. I figured that's what the cab would be like.

[SD70M-2Dude]

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.

[NorthWest]

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.

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

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.

[SD60MAC9500]

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.

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.

Presumably the "1010" is the reworked 265H, based on experience with 300 JT56ACe's in China.  Has the same displacement.

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.

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.

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.

There's no such thing as a 'wide cab'.

There is when compared to a narrow cab.

There's 2 mules, 1 with the F125 engine and the other has the 1010J.

But I think that "mule" is testing the C175 for the F125, not the 1010 for the SD70ACe-T4...

GEVO is 270 x 320

 

 

250 by 320, you mean?

Indeed I did... Post edited to remove typo...

whether ot not the 1010 is a "clean sheet of paper" design

 

 

Is everyone agreed it's 265 mm bore and 300 mm stroke? Was the 265 the same?

 

All I said was that the 265H displaced 1010 cubic inches per cylinder...

 

The GEVO is 250 x 320, so about 953 cubic inches per cylinder...

 

But GE kept the bore and stroke of the HDL when they developed the GEVO, concentrating on detail changes to improve the performance, reliability and fuel economy.

 

The published photo of the EMD engine showed an engine that appeared to be based on the 265H, in that it retained the cross flow head. The big flat intercoolers that hadn't been a success have gone, replaced by cylindrical air ducts. The turbocharger had changed ends and appeared to sit above intercoolers and exhaust gas coolers for Exhaust Gas Recirculation (both these features appear on the GE Marine V250 and probably on the T4 Gevo).

 

The 265H had a cast engine crankcase, and this basic casting could be reused on the 1010 with minor changes. The individual cylinder heads on the 1010 (if that's what we've seen) look a bit like those on the smaller Cat C175, suggesting influence in that aspect of design.

Also, all CAT makes for the most part are 4-stroke engines....

[YoHo1975]

Ugh, what a dumb name. Didn't we already hear that it was going to be the 1010 engine in the other EMD T4 thread?

[caldreamer]

That was what I was thinking.  Very similar to lwhat the GE Gevo's and the T4's are.  Very similar, bu not exactly the same.

[NorthWest]

I expect the same cab, same trucks, same aux cab and inverter box, same fuel tank, and modified radiator and long hood.

Does anyone know what the SD70ACe-T4 locomotive will look like?  Will it look likethe non tier 4 SD70ACe's or will it be completly different?

Only an insider might have an idea at this time, but I'd say it's safe to assume that it will have a family resemblance to what they were producing before Tier 4.
