Video: Lubrication System Should Make Monorail Extremely Quiet
In order to ensure that the "monorail monorail system Eugen Langen", as it was invented by its inventor, can be as whisper-quiet as the city planners imagine, Verkehrsbetriebe Wuppertal relies on the support of SKF: The wheel flange lubrication system is intended to reduce the friction between Lower the flange and rail flank and thereby reduce the noise emissions.
The monorail monorail travels in one direction on a continuous steel track and turns in loops at the ends of the line. The wagons hang on their bogies underneath. It traverses radii from 120 m at up to 60 kilometers per hour and is therefore much faster than, for example, trams. The drive units rolling on the rail consist of wheels arranged in pairs one behind the other. In contrast to conventional rail vehicles, the wheels of the suspension railway have two wheel flanges, and the wheels are equipped with special sound absorbers to reduce noise. The fact that the fathers of this special railway solution went up in the air is due to the limited space available:
The city center of Wuppertal was already very densely built up at the end of the 19th century. There was therefore only room for public transport above the river that gave the city its name. The enthusiasm for technology of the time and the spirit of optimism in the steel construction sector finally led to the implementation of the ambitious project. Today the route network measures 13.3 km, ten of which are directly above the river. At rush hour, 22 wagons run, three vehicles every ten minutes. The supporting structure consists of 468 inclined supports, between which the track-leading bridges are installed.
Construction began in 1898. After a construction period of three years, the railway was put into operation. Around 19,200 t of steel were used for the scaffolding and stops. The construction costs at that time amounted to 16 million marks. Even then, the route was very controversial over a section where the train was to be carried out directly between the houses. In the first half of the 20th century, the suspension railway was very difficult.
After the First World War, the number of passengers dropped significantly: no wonder, some stations of the train were in occupied territory and the rapidly increasing inflation of the 1920s meant considerable economic problems. During the Second World War, the suspension railway was so badly damaged that operations were partially stopped. After 1945 the train was in a desolate condition - nevertheless, a quick, partly improvised reconstruction began. The network was expanded and constantly restored in the post-war period.
