Diesel locomotive Gravita 10 BB

For over 70 years, the Voith company of Heidenheim has been a supplier of vehicle parts, especially high-performance hydraulic transmissions. For the first engine developed completely in-house, the new company Voith Turbo Lokomotivtechnik GmbH & Co KG was founded, with headquarters in Kiel. The first engine, christened the Maxima 40 CC, had its public debut in 2006.

With an output of 3600 kW, it is the strongest single-engine diesel-hydraulic locomotive. Since it was designed from the outset as a modular family, the vehicle is also available in a different performance class as the Maxima 30 CC and Maxima 20 BB.

Despite the risk, a large number of orders were placed relatively quickly. This encouraged Voith in the project of developing a modular locomotive family for shunting and light line service.

A high demand is expected in this area for the next few years, as many older locomotives are due for replacement and diesel traction is preferred, especially in shunting service. After a short development time, Voith Lokomotivtechnik presented the first sample of the Gravita family at InnoTrans 2008. Five different performance classes are projected, from the four-axle Gravita 20 BB to the „chicks“, which go by the name Gravita 5 BB and which have only two axles. Although the vehicle had only existed as a prototype and was not yet widely tested, DB Schenker decided on more than 130 locomotives for the Gravita 10 BB in its 2007 bid invitation.

By now, the first units of the Gravita 10 BB are in use on the Northrail on German rail tracks. The designated DB machines are currently in production and will soon be seen in use nationwide under the series designation BR 260.

Apart from Northrail, another 5 locomotives went to Switzerland. Continuing this success, the next larger sister in this series, the Gravita 15 BB, was shown in Berlin in 2010. Although only 1.2 m longer than the Gravita 10 BB, it produces up to 1,800kW, making it as suitable for line service as it is for shunting. All locomotives built by Voith Turbo Lokomotivtechnik are also suited for multi-led traction with each other. The engine assembled under the serial number L04-15 001 is being exhaustively tested at present.

Scale and true to original small-sized model for adult collectors.

Only a toy transformer produced compliant with VDE 0551/EN 60742 may be used as a voltage source to operate this product.

Electrical equipment may not reach to domestic waste. According to the current terms of the country reference the electrical equipment must professional disposed.
