This 45 tonne Diesel-Electric Whitcomb centre-cab switching locomotive was manufactured by the Canadian Locomotive Company in Kingston, Ontario, in 1950. It was used to switch freight cars around quarries and aggregate companies in the Toronto area until the 1990s. No. 1 was purchased by the TRHC in 2007 to switch equipment around the museum and is powerful enough to move 6213, the heaviest locomotive in the collection and short enough to still fit on the turntable.
