EMD closed down local manufacture in an effort to reduce purchase price of Australian EMDs. Would guess the price per is something like the C44 now.
It seems at a glance that lots of the EMD family (in the US) from SD50 onwards is a potential rebuild candidate , and heaps of DC GEs , assumes Dash 9s .With PN's loss of the Mac Generation contract, the time for rebuild/withdrawal of the 90's maybe approaching. The 90's certainly appear vulnerable in their present form. I believe PN investigated extending their use further northwest but did not proceed. The inability to do a "straight swap" in the event of engine failure was an issue. Also axle load restrictions in Werris Creek yard meant they were not suitable for banking duties.
NS is updating lots of locos and pleasingly those SD60s are getting or being rebuilt with Tier series EFI 710 16s rather than the wuzy 710 12 Eco .
Had that Tier 0 90 class been serious it would have grown later EM2000 computers , EFI and an electronic air brake system .
I believe the Yanks are claiming a 7% fuel consumption reduction but I think NS also add their own brand of split cooling as well .
I think the SD60 DC had a similar poverty pac 3800 Hp 710 16 as the 90s and upgraded they crank out 4000 odd .
A 90 could use a more serious alternator and traction motors and with electronic AB probably have the ECP fit out as well .
The 5000/5020s weigh more than 90s so an axle load increase may not be an issue .
Maybe not a cheap exercise but it would future proof the smallish fleet , make them potentially cleaner more reliable/economical and available to pull the ECP coal rakes . I can't see an export GT46ACE being cheaper landed here .
With a bit more reading it's obvious that some US operators have been or are rebuilding just about anything with 4000 odd horsepower preferably with split cooling .To address your last two posts:
The big issues with the EMDs seems to be cooling capacity EFI and Siemens electrical gear in the SD60/70/90MACs .
The Siemens inverters etc are drying up so the logical solution is to convert to the Mitsubishi parts like the SD70ACe series got .
The 60s and 70s don't seem to be getting the ACe sized cooling group but are stepping up to Tier 0 or 1 emissions standards .
Canadian built 90 classes look very much like a lightweight SD60 on paper .
I think the flurry of rebuilds/upgrades was driven by perceived fears of the Tier 4 units compliance issues and the possibility of them being more expensive to feed . I haven't read any reports on how the 70ACE T4 goes but someone will eventually post their opinions .
The Americans aren't afraid to rail coal over long distances for power generation and neither should we be.The Yanks rail coal over vast distances these days in large part because of EPA regulations around power station SO2 emissions. Powder River Basin coal from Wyoming has a much lower sulphur content compared most of the stuff coming out of the US Midwest and Appalachia.
Climate change has been going on since the beginning of time , happens every day .No problem with your view, I disagree with it but that's fine about global warming or man made warming. Your view its natural etc etc that is fine your entitled to your opinion.
The global warming and the fictitious hokey stick you can hide from the sun by your best means .
I've lived in the same overall area for the last 50 years and no the summers are not hotter and dryer than they were in the late 60s early 70s . Ocean levels not higher and nowhere here is under water any more or less than it was then .
You want to curb emissions simple , stop the mass migration into Australia because birth rate isn't the reason our population is rising as sharply as it is . More people more resources , more resources more energy , more energy greater emissions .
Yes Global Warming - according to the once popular little fool . The dams will never fill and rain will never again touch the ground . Notice how wet its been all over in recent years ?
Modern coal fired power stations are better than the dinosaurs we have/had and far better than the brown coal burning ones .
Quite a number of first world countries are axing nuclear and going back to coal fired powered stations .
The southern states in Australia are and will continue to suffer because nut cases believe the PC rubbish that wind and solar are the answer . How so if sun doesn't shine and wind doesn't blow , its all good . People will suffer and die when its hot /cold/refrigeration browned out / Hospitals can't save lives .
What happens when the grid goes down ? Why of course they fire up the DISEASEL generator which laughs its stack off at the useless propellers and solar arrays .
With cleaner black coal burning power stations it doesn't have to be like this , and its an improvement on what has been used until recently .
I think its about time someone like Trump gave the rest of the world the finger and America looked after its own , protected its energy workforce and manufacturing industry .
Pretty much sums it up.Climate change has been going on since the beginning of time , happens every day .No problem with your view, I disagree with it but that's fine about global warming or man made warming. Your view its natural etc etc that is fine your entitled to your opinion.

My fundamental question is is it ok to pump crap into the air?
On the same basis why do we bother with sewerage treatment plants for water, catalytic converters on cars etc. Man made impacts have no impact on the eco-system right?
I think the issue for me is that the tag of man made global warming has been hijacked by political interests of both sides. Scientist backed the wrong horse for convincing people without an interest in science.
They were better off sticking to the fundamental issue of pollution. Most people can actually grasp that notion. Is it ok with the continual growth of the human pollution to grow?
The air is lovely China isn't.
If you fundamentally address air pollution you will address CO2 along with NOx H2S etc. The spin off is less greenhouse emissions to the atmosphere.
Unfortunately the ones that don't agree with "man-made global warming" because it ain't hot here will not listen.
However normally they do agree ultimately you can't poo in your in your own nest. Unless they enjoy the stench.
From Trains Magazine Newswire:And Mary said all that with a straight face, Because she's very serious about protecting victims. Get out into those disadvantaged communities and smell the diesel fumes, Mary. Thats what the most powerful nation in the world smells like. Mary won't be happy until everyone in those disadvantaged communities is sitting in the dark weaving baskets. Pillock. Sorry. Self-serving pillock.
Good luck getting Trump's EPA to approve "nearly zero emissions..."
SACRAMENTO, Calif. — The California Air Resources Board is asking the U.S. Environmental Protection Agency toughen nationwide emission rules on locomotives, ones that go beyond the current Tier 4 standard.
Diesel & Gas Turbine Worldwide reports that the California board, under the umbrella of California’s own Environmental Protection Agency, wants locomotives operated in the state to have zero or near-zero emissions. The board's chairman, Mary D. Nichols, says that new standards are needed to protect and clean up the air in “high-risk” communities, specifically ones close to rail yards.
“Reducing locomotive-related emissions and the resulting air toxic hot spots near rail yards is a high priority for disadvantaged communities within California and around the nation,” Nichols says. “A new generation of locomotives will also, once in operation, offer fuel savings to the railroad industry."
India has ordered 1000 units from GE to be delivered over the next 10 years
Locos to be Tier 1, so probably the "light GEVO"
http://www.railwaygazette.com/news/single-view/view/ge-transportation-unveils-indian-railways-evolution-locomotive.html
300 to be 6000hp, so 16 cylinder. Will these engines be sourced from CRRC Qishuyan? http://www.crrcgc.cc/qsyen/g3787.aspx
Production of 16 and 20 cylinder EMDs at DLW will continue at around 300 units per year
Pakistan has ordered 20 additional ES43ACi, an extension to the order for 55 currently being delivered
