giving them the designation of AC4400CW-CTE. This software package is now standard on a portion of their ES44ACs as well. CTE limits tractive effort to mimic TE level of Dash series locomotives. In 2018 Union Pacific placed a small order for 20 rebuilds from GE of their AC4460AC fleet and later announced over the next fifteen years they will be upgrading 1000 of their AC4460ACs and AC44s into what they call a C44ACM. Unlike CP, the original 20 rebuilds did not receive a new crew cab. CSX and Wabtec have announced a partnership in rebuilding CSX's large AC4400CW fleet. An initial batch of 10 CW44ACs were rebuilt at Wabtec's Erie, Pennsylvania facility, with 40 more to follow into 2020. The rebuilds will be numbered in the 7000, 7200, and 7500 series and CSX is referring to them as CM44ACs. Operators AC4400CW owners and operators past and present include: In popular culture The plot of the movie Unstoppable required Denzel Washington and Chris Pine to climb aboard the lead locomotive of a runaway freight train. To film the movie, four Canadian Pacific AC4400CW locomotives (numbers 9777, 9758, 9782, and 9751), were repainted as two fictional "Allegheny and West Virginia Railroad" locomotives (nos. 777 (nicknamed "Triple 7") and 767). 9777 and 9782 were painted as 777, while 9758 and 9751 were painted as 767.
