The GE U18B diesel-electric locomotive was introduced by GE Transportation as a branch line road switcher locomotive in 1973. The U18B was not a popular seller with GE only making about 150 of them, and they were mostly purchased by Maine Central and Seaboard Coast Line. The Maine Central referred to their U18Bs as the Independence class and named their units after revolutionary war heroes.
