What Happened To CSX's AC6000s?

Inm their recent run of N scale AC6000s, Broadway Limited painted the CSX units in the YN3 "dark future" scheme that dates from 2002. Checking photos on the web, I've found that the unit unbers BLI ran with this scheme actually had them on the prototype. (BLI photo)

After last week's post on UP's AC6000, I learned that a spotting feature that distinguished "full" AC6000s like CSX's from "convertible" or "rebuilt" units on UP was the exhaust stacks. An "original" or "full" AC6000 has twin exhaust stacks like the CSX unit in the model photo above. "Convertible" or "rebuilt" units have a single exhuast stack similar to an AC4400 or ES44. This also applied to CSX units that had their engines modifed or replaced.

Unlike the UP units, the CSX units had their AC6000s with AC-radial trucks. BLI reflects this difference on its models.

It's a little harder to track down concrete information on the fate of CSX's AC6000s. The Wikipedia entry I linked last week says that CSX received three pre-production units numbered 600-602 in December 1995. Due to problems with these units, full production was delayed until 1998. GE then delivered "full" units 603-699 and 5000-516 between October 1908 and April 2000.

As with UP, CSX had continuing problems with the "full" units. Per the link,

603-699, 5000-5016's original prime movers replaced with 4,600 hp (3,400 kW) 16 cyl. GEVO prime movers and new computer equipment essentially making them ES46ACs. CSX classifies these units as CW46AHs. 5015 and 5016 were both classified as a CW60AH.

According to another link,

Since 2008, many CSX units have since been equipped with GEVO electronics essentially dubbing them as "ES60AC's", while other units are reported to be equipped or retrofitted with GEVO-16 prime-movers (though nearly all of them simply have modified engine blocks or are retrofitted with 7FDL-16 engines).

So far, I haven't been able to find concrete information on which specific CSX units received which specific modifications.

In the YouTube short below, you can see a CSX AC6000, but if you look at the roof of the long hood, you can see that the as-built twin exhaust stacks like those on rhe BLI model have been replaced with a single, wider exhaust stack like on an ES44.

I will be on the lookout for N scale parts that might be used to modify the BLI model.

According to the last link above, CSX 603-665, 667-699, and 5000-5016 weere sold to Progress Rail in 2018. 600-602 remained on CSX property but out of service. CSX 601 is the "Spirit of Waycross" unit, while 602 is the "Spirit of Maryland". 666 at some point was renumbered to 656 due to the number's Biblical connotations.

In 2019, Progress Rail leased 10 units (two for parts only) to the Western New York & Pennsylvania Railroad, which numbered them 6000-6007. The YouTube video below shows the WNY&P units in servicxe late in their career:

The description of the video reads,

In 2019 the Western New York and Pennsylvania railroad entered into a lease agreement with Progress Rail or PRLX to rebuild/ lease 8 former CSX AC6000’s to replace the WNYP’s aging fleet of 6 MLW M636’s. Slowly the AC6000’s began to phase out the M636’s between 2019-2020. The WNYP’s AC6000’s numbered 6000-6007 became the main powerhouse of the railroad making runs up keating summit with only 2 locomotives instead of 3-4. However over the next few years the WNYP’s traffic was steadily decreasing and due to this only 3 out of 8 AC6000’s would see regular service. In 2024 the railroad lost one of its largest customers who moved fracking sand out of Emporium PA eliminating runs up the Keating Summit, also in 2024 70 miles of track between Sagertown and Jamestown would be taken out of service further more limiting the traffic of the WNYP and with this cut in traffic saw the nail in the coffin for the AC6000’s. On May 28th AC6000’s 6000, 6003, 6006, and 6007 were moved to Meadville PA where Norfolk Southern would take them to an unknown fate.

All were off the WNY&P late in 2024. According to the link above, Aberdeen, Carolina and Western Railway rebuilt former CSX AC6000CW #666/PRLX 656 into a bar under the name "Engine Room ‘87" in 2024.
