76253

76253 is a model designation for a series of diesel-electric locomotives produced by General Motors Electro-Motive Division (EMD) in the mid-20th century. Introduced in 1953, the 76253 series was part of EMD’s broader line of road-switcher locomotives, designed primarily for freight hauling. The model was built on the same chassis as the earlier 7600 series but featured updated components, including a more powerful prime mover and improved electrical systems.

The 76253 was powered by a 1,600-horsepower (1,200 kW) 567C diesel engine, paired with an EMD D25C or D27C generator to produce electrical power for traction motors. These locomotives were equipped with a single cab, a common design choice for road-switchers, which allowed for easier maneuvering in both mainline and yard service. The model was produced in limited numbers, primarily for North American railroads, and was often used by smaller regional carriers or secondary lines.

The 76253 series was notable for its reliability and efficiency, though it was eventually overshadowed by more advanced models like the 645 series introduced in the late 1950s. Many of these locomotives were later rebuilt or upgraded with newer components, extending their service lives well into the 1970s and beyond. Some examples remain in operation today, preserved by museums or private collectors as part of rail heritage efforts.

The designation "76253" refers to the locomotive’s specific configuration, where "76" indicates the general road-switcher series, "2" denotes the number of axles (B-B), and "53" signifies the year of introduction. This model was one of several in EMD’s lineup during the 1950s, reflecting the company’s focus on standardized designs for cost-effective production.
