The DB AG would have been well advised to make use of such a beautiful diesel switch engine like the Henschel type DHG 700 C, but at least in the world of model railroading this is becoming reality. At least a similar looking unit, the type DE 500 C, with only diesel-electric drive and less power was allowed to prove itself as road number 259 004 from September 8 to December 19, 1983 on the DB as a loan locomotive. The Henschel Works in Kassel produced diesel locomotives with cardan drive for medium heavy and heavy switching work on industrial and branch line railroads as far back as the early Sixties. While the fourth generation Henschel locomotives still had rounded body shapes, this changed with the fifth generation starting in 1973 to squared-off superstructures. The model shown here belongs to this generation. The designation DHG 700 C stands for a diesel hydraulic locomotive with cardan drive, about 700 HP performance and three sets of driving wheels. On this unit, a diesel motor transmits its output to a hydrodynamic Voith transmission with flange-mounted multi-step gears and reversing gear and this output is again transmitted by means of cardan shafts to the wheel sets. In addition, the multi-step gearing enables changes in speed and allows a maximum speed in the switching range of 30 km/h / 19 mph and in the regular range a maximum speed of 50 km/h / 31 mph. All of the propulsion components are built into a rigid frame with the small wheel spacing guaranteeing reliable operation on curves with a radius of only 80 meters / 262-1/2 feet. Henschel produced 55 units of this model between 1973 and 1985. These locomotives were placed into service mainly with mining companies (Saar Mining Company: seven units) and steel producers as well as chemical firms. Automobile manufacturers such as Volkswagen (seven units) were also among the customers for this locomotive.
