The Grand Trunk introduced the Maple Leaf on May 15, 1927. The train operated on an overnight schedule between Chicago and Montreal, Quebec. In 1932 it began carrying a through sleeper for New York. In May 1937 the Grand Trunk renamed the westbound Maple Leaf the La Salle. The eastbound Maple Leaf was known as the New York Maple Leaf between 1938 and 1939. The name Toronto Maple Leaf was briefly applied to a Chicago–Port Huron, Michigan train in 1938.[1]: 189 In 1938 the New York Maple Leaf was one of several Grand Trunk trains to receive Class U-4-b 4-8-4steam locomotives built by the Lima Locomotive Works.[2]
The Maple Leaf operated on a daytime schedule between Chicago and Toronto in the 1950s. It carried a Chicago–Montreal through sleeper, a Chicago–Detroit through coach, a Port Huron–Toronto cafe/parlor car, parlor cars, and coaches. A dining car operated between Chicago and Lansing, Michigan.[3] The Montreal sleeper ended in 1958.[1]: 191
Beginning in 1961, the Maple Leaf went via the more populous cities of Kitchener and Guelph, whereas it had previously taken a route via Brantford and Hamilton for the trip between London and Toronto.[4] By October 1963 the similar itinerary train, the Inter-City Limited had followed suit for its westbound trip.[5]
In 1966 the Grand Trunk renamed the westbound Inter-City Limited the Maple Leaf, thus making the Maple Leaf a daytime round-trip between Chicago and Toronto.[1]: 191 After the truncation of the International Limited to Port Huron on June 23, 1970, the Maple Leaf was the Grand Trunk train on the Chicago–Toronto route. Amtrak discontinued all remaining Grand Trunk trains when it began operations in 1971. Service over the Grand Trunk resumed on September 15, 1974, with the introduction of the Blue Water Limited.[6]: 203–204
