NorthWestThe article doesn't say anything about which units are going to be repowered, only that they are low horsepower engines. UPY 2005 is not new, it is the genset prototype which due to its internal layout can't be effectively repowered by a single prime mover.
Since the sample unit was a GP40, chances are the rest of them will be GP38-GP40-GP60 units.
The UPY 2005 could be reworked, after all the C415 had a single prime mover. It probably wouldn't be in the same program, since its frame doesn't look long enough to accommodate all the stuff on the trial unit. But it could be redone to be a lower hp unit.

NorthWest That's actually the first genset, which is unique and has been around for a while. Not sure what these units will actually be, other than maybe the PR24Bs that they ordered?

Says UP in the article..
The switcher units are being repowered by Progress Rail in Patterson, Ga., and will join UP’s yard locomotive fleet in the Bay Area and Sacramento beginning in fall 2018. The new switchers are expected to reduce PM (particulate matter) and NOx (oxides of nitrogen) emissions by more than 90% during operations, when compared to older locomotives. The new single-engine locomotives are designed to ultimately replace the genset concept UP developed with NRE in 2005. The railroad says it is the only Class I operating Tier 4 switchers and is the first Class I to pursue Tier 4 repowers.
=============================
The resemblance between those two locomotives is like a modern C415 and the original C415.

caldreamer Your right, it does look a lot like the old Alco C415's

I tried to sell my two cents worth, but no one would give me a plug nickel for it.
I don't have a leg to stand on.
When I first saw this photo of UP's new switch engine I had a feeling of Déjà vu because of the resemblance this engine has with the Alco's C415.
Who would have thought?
