The Corps of Canadian Railway Troops were part of the Canadian Expeditionary Force (CEF) during World War I. Although Canadian railway units had been arriving in France since August 1915, it was not until March 1917 that the units were placed under a unified headquarters named the Canadian Railway Troops. They were redesignated as the "Corps of ..." on 23 April 1918. The corps was disbanded along with the rest of the CEF on 1 November 1920.^[2]

The initial 500 men came from the Canadian Pacific Railway, but overall the railway troops had 13,000 members.^[1]
