now a 100% subsidiary of Caterpillar Inc. The engines still carry the MaK logo. One example of the success of this organisation is the use of four engines of the type MaK 9 M 43 C in the cruise ship AIDAdiva. The MaK product line as of August 2015 consists of six medium-speed four-stroke diesel and dual fuel engine models. They range in power from 1,020 to 16,800 kW. Current models apply flexible camshaft technology (FCT) to reduce or eliminate visible smoke at partial load. FCT also said to improve performance and load pick-up. Locomotives In the 1950s and 1960s diesel locomotives of the 'connecting rod' with jackshaft drive type were built and sold to numerous private companies to replace steam locomotives. During the 1950s the plant produced locomotives for the Deutsche Bundesbahn, including the DB Class V 60, DB Class V 65, DB Class V 80 In 1965 native locomotive production began to use cardan shafts as part of the transmission system. During the 1960s further locomotive models were produced for the Deutsche Bundesbahn including the Class V 90's, DB Class V 100, DB Class V 200 and DB Class V 160. A third program of locomotive building began in 1979 - based on the standards (Arbeitskreis Standard-Diesellok) produced by the Federal Association of Railways (Bundesverbandes Deutscher Eisenbahnen) which required the use of standard interchangeable components. In the exterior design right angles and flat steel predominate - primarily for cost reasons, internally a switch to faster running engines was made, with engines from MTU being used. The G 1206 BB; a development of the G 1201 BB, with numerous intermediate models, proved notably successful being in production for decades, with a new shunting version introduced in 2007. In the harsh economic climate of that time the company tried to expand its range - and its customer base. Using electrical components from the Swiss-German company BBC MaK started production of diesel-electric locomotives - some were successful, notably the EN 6400 of which 120 were bought by Nederlandse Spoorwegen. In 1992 the name of the company was changed to Krupp Verkehrstechnik GmbH (with the corporation of some other companies in the Krupp group). 1994 brought a sale to Siemens and became part of Siemens rail technology (Siemens Schienenfahrzeugtechnik SFT). On 1 October 1998 the factory in Kiel along with a branch plant in Moers was sold to Vossloh AG. Vossloh Rail
