The GE C44-9W, or Dash 9-44CW, is manufactured by General Electric Transportation Systems of Erie, Pennsylvania. Debuting in 1993, the C44-9Ws proved very popular with many North American railroads placing orders such as Santa Fe and BNSF (the liveries featured in this pack) as well as Chicago & North Western Railway, CSX, Southern pacific, Canadian National Railway, Union Pacific Railroad and BC Rail. The similar Dash 9-40CW was purchased by Norfolk Southern. Due to stricter emissions requirements introduced in 2005, the production of the Dash 9 was replaced by the GE ES44DC.

At its largest the Atchison, Topeka and Santa Fe Railroad would own over 13,000 miles and the routes which made up its system would become some of the most heavily and strategically used throughout the West that remains so to this day. In 1994 it agreed to merge with north-western giant, Burlington Northern, to form the Burlington Northern Santa Fe Railway, now known as simply BNSF. The railroad's renowned War Bonnet livery has been made in several variations ranging from the more popular silver and red with yellow trim to the blue and yellow.
