The following is a list of locomotives produced by GE Transportation Systems. All were/are built at Fort Worth, Texas or Erie, Pennsylvania, in the United States. Most (except the electrics, the switchers, the AC6000CW, and the Evolution series) are powered by various versions of GE's own FDL diesel prime mover, based on a Cooper Bessemer design and manufactured at Grove City, Pennsylvania.
Because their model designations start with "U", they are known colloquially to railfans as "U-Boats".
