    The EMD SD60 was a 3,800 horsepower (2.8 MW) 6-axle diesel-electric locomotive built by General Motors' Electro-Motive Division. Intended for heavy-duty drag freight or medium-speed freight service, it was introduced in 1984, and production of SD60 variants ran until 1995.

    The development of the SD50 and SD60 series in the late 1970s and early 1980s was spurred by the introduction of 3,600 hp (2.7 MW) GE B36-7 and GE C36-7 locomotives by EMD's main competitor General Electric. In 1980, the EMD SD50 series locomotives were introduced, but these were not a success owing to poor engine reliability. EMD therefore quickly commenced development of the SD60 series. Although the carbody and frame are nearly indistinguishable from the SD50, the SD60 featured the new 16 cylinder EMD 710 prime mover. These replaced the overstressed EMD 645 that proved so problematic in the SD50. The SD60 was also fitted out with upgraded traction motors, a new design of trucks, and a microprocessor-based control system. The SD60 proved to be much more reliable and fuel-efficient than the SD50, and did much to repair the damage to EMD's reputation caused by the unreliable SD50. EMD claimed that three SD60 units could replace four of the industry standard workhorse SD40-2.

    Several variants of the SD60 were built, including:
    The standard SD60, which had a conventional hood unit configuration.

    The SD60F, ordered and operated by Canadian National, had a full-width cowl body and four piece windshield.

    The SD60I "Whispercab" variant featured a cab (with a full-width short hood) that was isolated from sound and vibration using a system of rubber gaskets. The same cab was later used on the SD70I, the SD80MAC and the SD90MAC. Only Conrail ordered this engine. All of these locomotives now belong to Norfolk Southern and CSX

    The SD60M, first ordered by the Union Pacific featured a "North American safety cab" design with a full-width short hood. Early models featured a three-window design with vertical windows (nicknamed "triclops"); later production used two windshield panes that were sloped back, and a somewhat shorter nose.

    The SD60MAC was a variant of the SD60M with AC powered traction motors. Although four demonstrator SD60MAC units tested on the Burlington Northern proved the viability of EMD's AC traction system, all subsequent orders were for the SD70MAC

    The standard SD60 looks very much like an SD50.

    Note the hood doors under the radiators. There are eight, as compared to only six on the SD50. This is the only external difference.

    There are several widenose versions: SD60M (2-window), SD60M (3-window) and SD60I. The first two describe the appearance. The 3-window version was made in 1989-90 and the 2-window after that. The SD60I looks like an SD60M (2-window) with a seam running over the nose. This is the same nose as on the SD75I, SD80MAC and SD90MAC.

    The cowl-body SD60F is such a different-looking engine that I'll cover it separately.

    Are we going to get a mini thread on the SD60MAC?

    I consider AC models to be substantially different from corresponding DC models. I will get around to an SD60MAC thread, unless someone else does it first.
