    In the 80s and early 90s, a new generation of freight cowl units was made. CN was the primary buyer. All of these models share their overall shape, including the "Draper taper" behind the cab. Thus, they are all often confused, despite not all coming from the same manufacturer.

    The HR616 was the first Canadian-cab cowl unit. They were the last standard-gauge Alco-engined locomotives made for the North American market, in 1982. They were one of only two models in the Bombardier (successor to MLW) HR (High Reliability) series. The other was the HR412, a new version of the M420W. It was not a cowl unit.

    The HR616 did not live up to its name. They were delivered as 3200 hp units, soon derated to 3000 hp (not a good sign). Between 1995 and 1998, all were retired, along with all Alco/MLW/Bombardier power on the system. None found second homes, unlike many older Alcos. Meanwhile, all SD40-2Fs, SD50Fs, SD60Fs and C40-8Ms have survived.

    The HR616 can primarily be distinguished from its EMD and GE counterparts by the huge banks of louvers at the rear and on the Draper taper (which does not extend to the frame). It also has no side portholes, unlike the other Canadian cowls. It has Dofasco trucks (like the C40-8M) and cab numberboards (like the SD50F). The fuel tank is shaped like that of a GE locomotive, but is not as angular.
