The Voith Maxima locomotives are a new family of diesel-hydraulic locomotives built by Voith Turbo Lokomotivtechnik GmbH & Co. KG., a subsidiary of Voith. The most powerful single-engined diesel-hydraulic locomotive in the world, the Maxima 40CC is rated at 3,600 kW.[5] 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. In 2008 a third model, the Maxima 20BB, a 4 axle B'B' machine 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 are marketed as Legios General.[2]

In the 1990s Voith Turbo, a well-known German transmission manufacturer developed the new LS 640 reU2 transmission which was to be used in a new, high-powered locomotive series by MaK, the predecessor company of Vossloh Locomotives. MaK was counting on DB to order a large number of these new locomotives, but with German reunification and the inheritance of many DR Class 132 locomotives, DB saw no need for an order anymore.[6]
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.[7] The locomotive design won a red dot design award in 2007.[1] A new factory in Kiel was established in 2006 by Voith to manufacture the new locomotives.[6][8][9]
In 2008 at Innotrans Voith added a third potential model to its Maxima range, the 4 axle Maxima 20BB.[10] The type was expected to be a competitor for a 200 locomotive order from Deutsche Bahn for diesel locomotives for passenger and freight services to replace the "DB V 160 family" of locomotives;[11][12][note 1] in 2011 the Deutsche Bahn AG order was won by Bombardier Transportation with a new multi-engine type of its TRAXX platform.[13][14]
The locomotive's body consists entirely of steel. Both cabins have two seats (one for the train driver and one for a relief driver or supervisor) and have a standardised and ergonomical control desk. The cabins also have air conditioning and are equipped with all modern needs of today's operating conditions.[15]
Powered by either an 16VDZC or 12VDZC engine by Belgian engine manufacturer Anglo-Belgian Corporation, rated at respectively 3,600 kW or 2,750 kW, the locomotive can reach a top speed of 120 km/h (160 km/h optionally) and has a maximal tractive effort of 519 kN. The normal tractive effort is 408 kN. The LS 640 reU2 "Turbosplit" transmission allows for a separated traction and wheelslip control of each bogie. This is the first locomotive series equipped with this new technology. Brake equipment consists of electro-pneumatic and engine compression brakes. The smallest drivable curve radius is 80m. The locomotive can take up to 9,000 or 10,000 l of fuel, depending on the configuration.[16]
The locomotives are assembled at a new plant next to the Nord-Ostsee-Kanal in Kiel. Large maintenance and overhauls will be carried out in a new central workshop in Cologne, to be operated jointly by Voith Turbo and HGK.[17]
Voith initially offered 2 variants of this locomotive: the most powerful version is the Maxima 40CC with 3,600 kW power, intended for freight operators with heavy trains of up to 3,000 tonnes. A less powerful version is the Maxima 30CC with 2,750 kW power, primarily intended for freight operators with trains of up to 2,500 tonnes or passenger operators.[5] A third version the Maxima 20BB was added to the range in 2007.
After the exhibition of the demonstrator locomotive at the InnoTrans 2006 fair, it was tested on several German main lines to receive German certification. It was also tested on the Velim test ring and also went to Norway and Sweden for thermal testing. Final German certification was granted on 23 December 2008 by the German rail authority EBA.[18][19]
A second demonstrator locomotive was built and equipped with Dutch and Belgian safety systems for obtaining Dutch and Belgian certification. It was tested in the first and second quarter of 2008 in the Netherlands, and in Belgium in the fourth quarter. After Dutch and Belgian certification the locomotive will be passed on to HGK for testing.
A third and last demonstrator locomotive is being built and will be used to obtain certification in Poland, Sweden and Norway.
As of 2008, 32 locomotives have been ordered, with options for a further 29:
Voith signed an exclusive contract with Saxon model building company Sächsische Waggonfabrik Stollberg to build a H0-model of both Maxima variants. All parts of the locomotive will be engineered and made in Germany.[28]
