Constructed between 1908 and 1911, the station was built as a joint venture between the Canadian Northern Railway, National Transcontinental, Grand Trunk Pacific Railway and the Dominion government.[1] The first train to enter the station did so on 7 August 1911, with the official opening the following year on 24 June 1912.[2] Union Station was designed by Warren and Wetmore,[1] the architects responsible for Grand Central Terminal in New York City.[3] Designed in the Beaux-Arts style and constructed from local Tyndall limestone,[2] Union Station was one of Western Canada’s largest railway stations.[1] The building extends for 350 feet (110 m) along Main Street, with the entrance close to the intersection of Main Street and Broadway.[4] The building's entrance doors are located under a decorative iron canopy that projects from the austere white limestone.[4] Atop the building is a large dome.
