The V 300 6 Axles, Powerful, and Fast. Krauss-Maffei built a more powerful, faster version of the class V 200 on the basis of the V 200, but with 6 axles. The locomotive was almost identical with 3 units built for the Yugoslavian State Railroad. A great advantage of this 20,270 mm / 66 foot 6-1/16 inch long and 140 km/h / 88 mph fast locomotive was that it could be used on track with grades and curves and with shallow roadbed because the axle load was a low 16 metric tons compared to other locomotives. The internal designation at Krauss-Maffei for the locomotive painted in blue was ML 2200 C´C´. Experimental runs and tests with extreme loads were conducted on the Black Forest line and on the Semmering line in Austria, and this locomotive passed them with flying colors. Despite this, the locomotive was rebuilt to increase the performance from 2,200 horsepower to 3,000 horsepower and was painted in red with white striping. The new designation for the locomotive was ML 3000 C´C´. Despite the impressive technology, the German Federal Railroad did not order this locomotive as a regular production unit, but it took ownership of this single unit in 1963 after difficult negotiations with the builder and designated it as the V 300.1. From that time on the locomotive was on the DB's roster, where it was used in service similar to that for the V 200. In 1977, it was retired as road number V 230 001-0. An attempt to sell it to Italy failed and it ended up as scrap. Despite its being a single unit, it was an important experimental vehicle for Krauss-Maffei. The valuable data from experimental runs with this impressive machine flowed into the further development of large diesel hydraulic locomotives and resulted in sales to North America and Spain.
