Transportation Corps Branch Insignia Wheel

A ship's steering wheel, superimposed thereon a shield charged with a winged car wheel on a rail, all of gold color metal, one inch in height.

In 1919, "a winged car wheel, flanged, on a rail, surrounded by a rim one inch in diameter" was approved as the insignia of the Transportation Corps. The Army Reorganization Act, 4 June 1920, placed all transportation except military railways under the Quartermaster General. The Transportation Corps essentially in its present form was organized on 31 July 1942 as a result of the Army's reorganization and has functioned since then as one of the services. The present Transportation Corps insignia is based on that of the World War I Corps, with shield and ship's wheel added. The winged car wheel is for rail transportation; the Mariner's helm for transport by water. The U.S. highway marker shield is for land transportation.
