The United States Air Force Locomotive No. 1246 is a historic diesel-electric railroad switch locomotive on display at the Fort Smith Trolley Museum in Fort Smith, Arkansas. It was manufactured in 1953 by the General Electric Company in Schenectady, New York, in fulfillment of a contract with the United States Air Force for eleven of its 44-ton locomotives. It is believed to have spent all of its productive life at Grissom Air Force Base in Indiana, and was acquired by the museum in 1992.

The locomotive was added to the National Register of Historic Places in 2006.
