Voith Maxima

The Voith Maxima are a family of diesel-hydraulic locomotives built by Voith Turbo Lokomotivtechnik GmbH & Co. KG., a subsidiary of Voith.

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 2008 a third model, the four-axle Maxima 20 BB, was added to the range. In January 2010, Czech company Lostr (after September 2010 renamed Legios) signed an agreement to manufacture under license the Voith Maxima locomotives. The Czech built locomotives were marketed as Legios General.

Voith had supplied components to the railway industry since the 1930s - in particular its hydraulic transmissions.

Merger of the Deutsche Reichsbahn and Deutsche Bundesbahn in the 1994 resulted in the German state railways acquiring many high-powered diesel locomotives of the DR Class 130 family, which reduced any opportunities for sale of a high power transmission to the Deutsche Bahn in the medium term.

However, in 2004 Nord-Ostsee-Bahn acquired a contract to operate the Marschbahn from December 2005, 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. Initially the service was to be operated by the MaK DE 2700 type, before the new R3000 locomotives were built. The LS 640 reU2 transmission (input power 4.2 MW) was a result of development work by Voith for the R3000 locomotive's transmission. The 'Turbo Split' LS 640 transmission was first exhibited at Innotrans in 2004 - a key feature of the new transmission was the ability to separately control two outputs from the input - enabling wheelslip control per bogie.

In 2005, Vossloh acquired Alstom's Meinfesa plant (Valencia, Spain), and with it a license to manufacturer GM-EMD based diesel electric locomotives, and as a result, it abandoned the R3000 development, instead offering the Vossloh Euro and Vossloh G2000 designs for mainline work. The Euro 4000 was offered to the Marschbahn instead of the R3000.

Because it lost an outlet for its new transmission, Voith began development of a new high-powered mainline locomotive - the Voith Maxima.

Voith then developed in house new high-powered diesel locomotive series along with single cab shunting and trip freight locomotives, the Voith Gravita series. With a development period of just 500 days, the first locomotive was ready in 2006 and presented at the InnoTrans 2006 fair. The locomotive design won a red dot design award in 2007. A new factory in Kiel was established in 2006 by Voith to manufacture the new locomotives.
