Comments on: High horsepower seventies style: ten thousand six hundred rated horsepower or is this ten thousand two hundred horsepower? CP Rail first #942 approaches the high iron at Staines, Ontario (east end Agincourt Yard) powered by Diesel Road Freight unit (CP class DRF-36d) # 4744 accompanied by MLW sisters #4550 (M630) and #4714 (M636), lashed up \’elephant style\’, on a warm, humid autumn1977 Sunday. The 4744 is the one and only example of MLW designated model #M640. The eighteen cylinder engine is rated by the manufacturer at 4000 horsepower. Even so CP considered the unit to be experimental and as such rated the unit as a DRF-36d with the same 3600 horsepower rating as the sister Road Freight units (sixteen cylinder 251E engine) within the 4700 series (source: C P Diesel Locomotives by M.W.Dean). Note the freight equipment at the head end: a blue Chessie \’Cat\’ System and the two red CP Multimark fifty foot box cars. Kodak Kodacolor II ASA100 negative transported by a Nikkormat EL.
