Twenty-ton locomotives that are driven like an automobile are buzzing along railroads at army camps and posts around the country, hauling soldiers and freight and fuel for army planes. These midget “autolocomotives” are gasoline-powered, with a clutch drive. They can haul trains of 10 to 15 regulation freight cars at average speeds of 15 miles an hour. One of these “mosquito” engines runs on a narrow gauge track at Fort Dix, N. J., where it hauls soldiers to and from the rifle range. One use of this fleet is to move gasoline tank cars from the main line to the storage point.
