Need an engine? Union Pacific is in the process of converting the AC6000CW fleet back to standard 4400HP AC4400CW (officially C44/60AC on UP's roster). The 6000HP experiment just didn't work out for UP. All of EMD's SD90MACs (with 6000HP) are off the roster and most of the AC6000CWs have been converted back. This unit, previous UP 7569, is waiting for is 4400 HP engine to be plopped in.
