CSX
AC4400CW locomotives
CSX rosters over 600 examples of the AC4400CW (designated
CW44AC) by the railroad, and these continue to be among CSX's most
powerful locomotives. Derived from the DC traction-motored Dash 9-44CW,
the AC4400s have AC motors, and the CSX units are receiving software
upgrades to increase their already impressive tractive effort. They are
a daily sight along the Pittsburgh Subdivision.
