When I saw this loco I thought it was a 3000 HP GE B30-7... but it's a 3200 HP Dash 8-32.
It was switching grain elevators 2 miles east of here and it came into town light for a run-around move.
It's the only existing B30-7 in NS paint and I believe NS still owns it.
The SD60 have SOU on them despite never being in SOU paint for some reason. Many C39-8 had SOU or NW on them and they never saw those paint schemes ether. For some reason engines ordered right after the merger were lettered for the previous names and that I don't understand.
I also don't understand why a highhood ex-SOU GP38AC I encountered had PRR on it.
The PRR and NYC reporting marks were how CSX and NS identified former Conrail rolling stock with (IIRC) CSX getting NYC and NS getting PRR.
How a ex Southern loco ends up with PRR marks is odd but I'd take a guess that it may have been a transfer to Conrail to replace a Conrail loco that may have been destroyed while on Southern rails.
