Train Simulator: Chessie System U30C Loco Add-On (2016)

General Electric established itself as an independent builder of mainline diesel locomotives in 1959 with its 2,500-horsepower U25B, and throughout the 1960s and into the 1970s, GE produced an ever-expanding - and more powerful - line of "Universal"-series diesels, which came to be widely nicknamed as U-boats.
