EMD 16-645F Possible uses... GP40X, GP50, SD40X, and SD50s

The EMD 645 family of diesel engines was designed and manufactured by the Electro-Motive Division of General Motors. Developed from the earlier 567 series engines, the 645 series engines entered production in 1965. All 645 engines are two-stroke 45 degree V-engines. Each cylinder is of 645 cubic inches (10.57 liters) displacement, hence the name; with a bore of nine and one-sixteenth inches (230.2 mm), a stroke of ten inches (254 mm) and a compression ratio of 14.5:1. Cylinders in each V-pair are directly opposite each other, allowing "fork" connecting rods for one bank of cylinders as all rods are always in compression throughout both engine cycles (competitor General Electric uses the more complicated "articulated" connecting rods as all rods are alternately in compression or tension throughout all four engine cycles and the simpler "fork" connecting rods cannot operate in tension).

As with all Select decoders there are also 16 separate horns, 2 separate brake squeals, and 2 bells include on this one sound profile! All changeable using CV48
