They’re former CEFX AC400CW’s that were built into AC44C6M’s these are the first batch - But the dash 9’s are still being rebuilt and the ones that are from KCS (ex BNSF) those will still stay in the late 4000 series
@@patrickspies1464 interesting that they're still classified as AC44C6Ms with that ''6'' in there. I know CSX is continuing with their AC44 rebuilds and some fresh pairs have been spotted lately.
When did they start with the 3900-series?
