Every two years the “Privatbahn Magazin”, a leading business paper in the industry, rewards ground-breaking new products and features in the rail sector with a prize for innovation. Winner in the category Energy and Environment: the Mercedes-Benz road-railer Unimog U 423 with railway equipment. The coveted trophy is awarded in the categories Rail Vehicles, Locomotives and Multiple Units, Components, Equipment, Railway Technology Products, Track and Infrastructure, Energy and Environment. A total of 20 exhibits at the trade fair Innotrans 2016 in Berlin were contenders.
The expert jury, comprised of specialists from rail companies, scientist and advisory board members of the Privatbahn Magazin, were particularly impressed by the Unimog and its environmental compatibility and economy. The focus was on the drive system with the 5.1 litre diesel four-cylinder OM 934 LA Euro VI engine rated at 170 kW (231 hp). This low-maintenance, high-torque Mercedes-Benz engine generation harbours high savings potential when it comes to fuel consumption, especially compared with conventional diesel shunting locomotives. Also in its favour is the fact that in its road-railer version the Unimog is fitted as standard with special tyres and rims for operation on standard gauge and broad gauge (1435 mm – 1676 mm).
Further advantages of this Unimog variant: fast rerailing and rail/road changeover possible with a hydraulic lifting and pivoting system, speeds on the rails of up to 50 km/h – forwards and backwards – and on the road of up to 90 km/h.
Unimog meets various requirements since 55 years
Ever since 1962, when the first 411a model Unimog with the 23 kW (32 hp) OM 636 four-cylinder diesel engine (construction period 10/1961-3/1993) was delivered for a customer in North Baden as a road-railer vehicle, its advantages in this application segment have been well known. He is considered as a fully fledged shunting vehicle with a towing capacity of up to 800 t and as an implement carrier for a varied range of tasks in the field of track infrastructure such as clear cutting work, track-cleaning, maintenance of the overhead lines, track-laying and for clearing snow.
