The DASH 9-44CW is another 4400 horsepower mainline freight locomotive built by GE Transportation. Like it's AC alternative, the AC4400CW, it has seen a successful run, with 3,668 units being produced for railroad usage.
In appearance, it is nearly identical to the AC4400CW, with the main difference being the location of the air conditioner. Instead of being located underneath the cab of the locomotive, it's placed behind it. It also features a modified version of GE's 752 traction motor, the 752AH.
The C44-9W was produced from 1993 until 2004 when it was outlawed by Tier 2 emissions and replaced by the ES44DC. Notable purchasers of the C44-9W were BNSF (with nearly half of all locomotives built at 1,697), Canadian National (203), Chicago & North Western (130), Southern Pacific (101), Santa Fe (100), and the Australian iron ore hauler Pilbara Rail (72).
BC Rail and Canadian National had purchased 4 and 22 locomotives respectively that were called C44-9WLs. The C44-9WL locomotives had a different shaped, 4 window Canadian style safety cab similar to the C40-8M with a high mounted bell; there are no other cosmetic, nor mechanical or electrical differences from a normal C44-9W.

A 4,000hp sibling, the C40-9/C40-9W, was also offered at the time.

Notes
⚠: Not Verified or Educated Guess
(1) GE lists the 7FDL16's HP for traction at 4365 as of 2016, earlier manuals list it at 4390.
(2) Ratings from an ES44DC. They both share 752AH traction motors.
(3) All locomotives also feature an automatic starter inside the cab.
