Railway operations were originally established by the United States Army to provide support to France and Great Britain after the United States entered World War I. The Army organized and deployed different types of railway regiments and battalions. As operations progressed, the railway units were used to support the American Expeditionary Forces as well. U.S. rail regiments moved both troops and supplies for the AEF and for the allies from the seaports to the front.
