Interesting post for some related CSX news, involving what appears to be a similar program to Norfolk Southern's AC44C6M's, except for C40-8W's. 

Interesting. I'll believe it when I see it. If so, perhaps this is why NS curtailed their 8.5 program. Or perhaps it was the 8.5 program that prompted GE to give the Dash 8 another look. 

Since you were skeptical, this should put a smile on your face. :)

What was originally rumored to be a DC to AC conversion of a test batch of C40-8Ws is actually just a DC refurb

I would have liked to have seen a Dash 8 DC to AC conversion yet, although possible it really is not probable. I work with a number of GE alumni and so far there is no AC traction motor that will fit into the legacy truck. Swapping trucks is cost prohibitive. This appears to be a thorough overhaul and update but not as ambitious as NS' 8.5 venture; i.e. EFI or split cooling. Even so, the Dash 8 is a good machine and hopfully GE has found a way to keep them around for many more years to come.

CSX did it.  There are three Dash 8's floating around that have had AC traction motors in the trucks and kept the original trucks.

I haven't heard of any such conversions on CSX. 

Are you sure that you're not thinking of the new C40-8WM's? Like we've been talking about, these new C40-8W rebuilds did not receive the initially expected AC upgrade. 

I'm not even aware of any other major Dash 8 rebuild programs that have happened at CSX, other than this test group being delivered now. The C40-8's are gone rather than be rebuilt for another 10-15 years of service, the B40-8's were partially derated before retirement but never entered a capital rebuild program, and C40-8W's have previously only seen overhauls or wreck rebuildings.

7771, 7807 and 7801 are still DC, but designated C40-8WMs on their new decals. They lack inverter cabinets.

The first AC4400CW, GECX 4400, rides on Dofasco trucks off of an old MLW unit, so putting AC motors on the standard Dash-8 trucks which have a wider axle spacing should be possible.

I know we're veering off topic but who cares? It's Saturday. GECX 4400 has always been an bit of a mystery. Many moons ago ABB rewired the one-and-only M640 with AC traction and, to conserve space, installed two traction motors per truck making it A1A, foreshadowing the ES44C4 by decades. A 3-phase AC traction motor is smaller than a DC motor and should fit anywhere a DC motor fits. Then again for whatever reason dropping an AC motor into a legacy truck has been problematic at best. Anyone else remember the F69ACs? I'd love to see 3rd generation locomotives or older get an AC refit but the financial argument thus far seems to be against it.

NSDash9 posted that all C40-8's have been retired and sold. Disposition details are in the link.

Someone mentioned in the comments that the new ET44AC's, also mentioned today in another post about several being tested or ready to be delivered to NS, were the killer of these already stored units.

But with the standard cabs already stored before these were delivered, I would think that they'll more likely push aside C40-8W's into storage or further non-rebuilt standard cab SD60's. 

The last three GP38AC's are officially now retired, too. Other than rebuilds and potentially N&W's first SD40 rejoining the active roster for a time before donation, that takes care of the last pre-Dash 2 road power (5 SW1001's, built after the introduction of EMD's Dash 2 lineup but of a model introduced in 1968, remain on the active roster).

There was an earlier one at Amtrak than the F69AC's.  F40PH 202 was damaged in a wreck the magicans at Beech Grove and they are magicans at times with how they can bring back a wreck.  Well they took her added a custom AC drive to her complete with 4 AC traction motors and put her back into service.  No special paint on her just sent her back into service.  It now is at the Publeo CO TTCI AAR test track out of service.

In response to the mention of CSXT having converted three DASH 8s into AC-traction units, I'm not aware of that having been done.  However CSXT does operate three AC4400CWs that GE upgraded in 2008 from standard units into high-tractive-effort (i.e. "AH") units by adding 18,500 pounds of ballast and various other enhancements.

Apparently being a NS rebuild prototype is a hazardous thing for a locomotive...

Second brand new GE cab to go on its side. Unreal.

And 4005 has apparently caught fire (as GEs sometimes do):
