The South Simcoe Railway Heritage Corporation is a not-for-profit historical organization. Founded in 1953 and later becoming the Ontario Rail Association,  the South Simcoe Railway Heritage Corporation name was adopted in 1987 when the Association took over operation of the CNR Beeton Subdivision, between Tottenham and Beeton, Ontario, for the purpose of running branchline steam train excursions.

The Corporation's collection of historic equipment includes a fleet of steam-era passenger coaches, freight equipment and locomotives. The pride of the collection is historic Canadian Pacific Railway steam locomotive #136. Built in 1883, when Sir John A. Macdonald was Canada's first Prime Minister, #136  helped build Canada's transcontinental railway and is unique in that it served the CPR from before it's completion right up until the end of steam operations in 1960. In 2000, #136 entered a third century of service!
