The Yuma Valley Railway is a heritage railroad in Arizona, which formerly operated an excursion passenger train on the rail line following the Colorado River levee between Yuma, Arizona and Gadsden, Arizona. The train has not operated since 2005, when the line was embargoed by the Bureau of Reclamation (see below). One locomotive and three passenger cars are currently (Feb. 2010) parked idle across the canal and south of the Yuma Quartermaster Depot.
