Eastern Railroad Discussion > CSX AC4400CW's

I am trying to sort out the current power status of the CSX AC6000CW's.  Digging around on the web I have read variously that, 1) their 6,000 hp prime movers were switched out with 4,600 hp replacements, 2) they were simply derated to 4,600 hp, and 3) they were derated to 4,600 hp but have been rerated to 6,000 hp again.  Anyone have the straight dope on this?

See:

I doubt they were boosted to 6,000 hp again.

They're 4400hp, not 4600hp.​

CSXT 603-699 & CSXT 5000-5016 still have EVO 16cyl prime movers but CSX has them derated down to 4400hp to conserve fuel at this time. 600-602 were preproduction AC6000's and did not receive the EVO 16's when their original 6000HP HDL's were removed when GE quit supporting the HDL power plant and instead had 4400HP GE FDL's installed. The 603-699 and 5000-5016 have had various units upgraded to AH status with software upgrades

According to the Bull Sheet they are CW46AC 

CW46AC/AH is used to differentiate them from the CW44AC/AHs. They're 4400hp.
