Diesel engines
The marine diesel engines division became Caterpillar Motoren GmbH & Co. KG in 1997 and is now a 100% subsidiary of Caterpillar Inc.[4] The engines still carry the MaK logo.[5] 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.[6]
Current models apply flexible camshaft technology (FCT) to reduce or eliminate visible smoke at partial load. FCT is also said to improve performance and load pick-up.
Locomotives
In the 1950s and 1960s MaK built several designs of rod-coupled diesel locomotives with jackshaft and coupling rod drive. These were sold to numerous private companies to replace steam locomotives.[1][7]
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[8]
In 1965 native locomotive production began to use cardan shafts as part of the transmission system.[9]
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.[8]
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.[10]
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.[1]
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).[1]
On 1 October 1998 the factory in Kiel along with a branch plant in Moers was sold to Vossloh AG. Vossloh Rail Vehicle Engineering (Vossloh Schienenfahrzeugtechnik GmbH) or "VSFT" was the new name.[1]
Under Vosslohs management the locomotives produced carried the traditional MaK logo. On 23 April 2004 the company was renamed "Vossloh Locomotives GmbH"[1]
