AC4460CW: CSX "6000 horsepower" livery

CSX designed a special livery for its 6000-hp AC6000CWs and SD90MACs, with double lightning bolts and yellow logos.. However, the first "AC6000"s delivered actually had the same 7FDL prime mover as the AC4400, and years later all the genuine AC6000s, which suffered from reliability and fuel-consumption issues, were de-rated to either that engine or the ES44's GEVO. These locos were dubbed "AC4460CW." Since externally they were virtually identical to the AC4400s, this livery seemed worth doing.
