Canadian Pacific 1238 is a preserved G5c class 4-6-2 "Pacific" type steam locomotive built by the Montreal Locomotive Works in 1946. It was purchased by George Hart, who used it for excursion service in the 1960s. It was later sold to Jack Showalter, who operated it on his Allegany Central Railroad from the 1970s to the mid-1990s. In late December 2023, No. 1238 was purchased by the Waterloo Central Railway, and they have plans to restore the locomotive to operating condition.

The Waterloo Central Railway (WCR) is a non-profit heritage railway owned and operated by the Southern Ontario Locomotive Restoration Society (SOLRS). In May 2007, SOLRS received joint approval from the Region of Waterloo and the City of Waterloo to run trains from Waterloo to St. Jacobs and potentially as far north as Elmira. On a typical operating day, the train runs three times a day on Tuesdays, Thursdays and Saturdays. In 2015, the railway lost regular running rights south of Northfield Drive to make way for the Ion light rail project. All Market Train service now runs between St. Jacobs Farmers' Market, the Village of St. Jacobs, and Elmira, Ontario.
