Canadian Pacific's first roadswitchers from General Moters were 17 GP7's roadswitchers aquired in 2 batches in 1952 and 1953 Of these, 3 were traded in for rebuild to GP35 and one was wrecked. Starting in 1980, CP started a program of rebuilding and remanufacturing their remaining 12 GP7's into yard and transfer switchers (among many others). The work involved chopping the high nose, removing the dynamic brakes and rebuilding the prime mover, electrical and controls. By early 1983 all but one had been rebuilt into the 1500-1511 series. #8418 was assigned as the Cranbrook yard switcher (among other duties) and from 1980 untill early 1984 I often wondered when she would finally be called in. Early in 1984 she disapeared from Cranbrook and was finally rebuilt. the following are 3 pics taken of CP's last GP7 #8418 in her origional configuration. First is in early July 1983.
