They reside in the 8100 series.Ģ018: The GE rebuilding craze continues with Union Pacific now joining in. The cabs get replaced and the electronics are updated. 50+ rebuilds are on the books for 2017 with work being split between NS Roanoke, NS Juniata and GE Fort Worth.Ģ017: NS #4001 was wrecked in the spring and is at Juniata pending evaluation.Ģ017: NS has earmarked 500 C44-9W's for rebuild to AC44C6M specs between now and 2022.Ģ017: CP has sent 30 AC4400CW's for rebuild to AC4400CWM (the same specs as AC44C6M) except the cores were built with AC traction to begin with. 16 AC44C6M's were completed by GE (12) and NS (4). They are in a striking version of the NS scheme - light blue and grey with yellow stripes. 4000, and 4001 were rebuilt in 2015 from 87, respectively. Two units were completed and released in December 2015. The rebuild work is being contracted out to American Motive Power (AMP) in Dansville, NY by GE or being done by NS at Roanoke. Norfolk Southern is planning a much more ambitious program than BNSF as NS wishes to rebuild all 125 C40-9's and then move to their C44-9W fleet which is more than 1200 units strong. The C40-9's undergo an extensive rebuild : A new wide cab, AC-traction equipment, emissions upgrades, new trucks and they are ballasted to 432,000 lbs. A1A-A1A (four powered axles, middle axle of each truck unpowered) arrangement. Unlike the BNSF program, these will use C-C trucks (six powered axles) vs. The goal here is to turn NS's C40-9 (standard cab) into wide cab AC-traction locomotives - essentially a new AC4400CW. Building off of the BNSF program, NS and GE embarked on a rebuild initiative very similar to the AC44C4M program.
