Initially, two versions of a 6-axle C'C' machine were offered with medium speed engines from the Anglo-Belgian Corporation: the Maxima 30CC and Maxima 40CC (the most powerful single-engined diesel-hydraulic locomotive in the world, rated at 3,600 kW (4,800 hp)).

In January 2010, Czech company Lostr (after September 2010 renamed Legios) signed an agreement to manufacture under license the Voith Maxima locomotives.

[6] However, in 2004 Nord-Ostsee-Bahn acquired a contract to operate the Marschbahn from December 2005,[7][8] and contracted Vossloh to build new locomotives ("R3000 CC") to operate it; the locomotive's design specifications were a top speed of 160 km/h (99 mph) and power of over 3 MW.

[8][9] Initially the service was to be operated by the MaK DE 2700 type, before the new 'R3000' locomotives were built.

With a development period of just 500 days, the first locomotive was ready in 2006 and presented at the InnoTrans 2006 fair.

[citation needed] A third and last demonstrator locomotive is being built and will be used to obtain certification in Poland, Sweden and Norway.

[34] Powered by either an 16VDZC or 12VDZC engine by Belgian engine manufacturer Anglo-Belgian Corporation, rated at 2,750 kW (3,690 hp) to 3,600 kW (4,800 hp) respectively, the locomotive can reach a top speed of 120 km/h (75 mph) (160 km/h (99 mph) optionally) with a starting tractive effort of 519 kN (117,000 lbf).

The LS 640 reU2 "Turbosplit" transmission allows for a separated traction and wheelslip control of each bogie.

Large maintenance and overhauls will be carried out in a new central workshop in Cologne, to be operated jointly by Voith Turbo and HGK.
