The HOKI 5200 was manufactured by Hitachi from 1958 to 1961, with a total of 20 units. This is a 30-ton capacity open hopper car with a unique design. There are two cars equipped with an operator cabin used to open and close the gate system bottom doors pneumatically for unloading, which were always included in the formation. Owned by Tosa Lime Industry as a private freight car, they transported limestone from the Tosa Lime Industry’s dedicated line through the TOSA Main Line from Tokano to Tano to the cement factory. These trains moved 100,000 tons of limestone monthly over a 13 km section, powered by the DF50 in dual formation.
