Elberfeld in the context of "Friedrich Bayer"

Wuppertal (German pronunciation: [ˈvʊpɐtaːl] ; lit. 'Wupper Dale') is a city in North Rhine-Westphalia, in western Germany, with a population of 355,000. Wuppertal is the seventh-largest city in North Rhine-Westphalia and 17th-largest in Germany. It was founded in 1929 by the merger of Elberfeld, Barmen, Ronsdorf, Cronenberg and Vohwinkel, and was initially called "Barmen-Elberfeld" before adopting its present name in 1930. It is the capital and largest city of the Bergisches Land.

The city straddles the densely populated banks of the River Wupper, a tributary of the Rhine. Wuppertal is located between the Ruhr (Essen) to the north, Düsseldorf to the west, and Cologne to the southwest, and over time has grown together with Solingen, Remscheid and Hagen. The stretching of the city in a long band along the narrow Wupper Valley leads to a spatial impression of Wuppertal being larger than it actually is. The city is known for its steep slopes, its woods and parks, and for being the greenest city in Germany, with two-thirds green space of the total municipal area. From any part of the city, it is only a ten-minute walk to one of the public parks or woodland paths.

A turbo generator is an electric generator connected to the shaft of a turbine (water, steam, or gas) for the generation of electric power. Large steam-powered turbo generators provide the majority of the world's electricity and are also used by steam-powered turbo-electric and gas-turbine-electric powered ships.

Small turbo-generators driven by gas turbines are often used as auxiliary power units (APU, mainly for aircraft).

Barmen is a former industrial metropolis of the region of Bergisches Land, Germany, which merged with four other towns in 1929 to form the city of Wuppertal.

Barmen, together with the neighbouring town of Elberfeld founded the first electric suspended monorail tramway system, the Schwebebahn floating tram.

Ronsdorf is a district of the German city of Wuppertal. It has a population of about 22,500. Ronsdorf was first mentioned in 1494, and in 1745 it received its town charter. It was founded a few years earlier by Elias Eller when he relocated the Zionites there from Elberfeld. Ronsdorf was made a part of Wuppertal in 1929.

In addition to the town, Ronsdorf consists of the villages of Heidt, Erbschlö, Holthausen, Blombach, Linde, Marscheid, Großsporkert, Kleinsporkert and Kleinbeek.

The Wuppertaler Schwebebahn (English: Wuppertal's Suspension Railway) is a suspension railway in Wuppertal, Germany. The line was originally called in German: Einschienige Hängebahn System Eugen Langen (English: Single-Rail Hanging Railway, System of Eugen Langen) named after its inventor, Eugen Langen. It is the oldest electric elevated railway with hanging cars in the world. Being grade-separated, it is considered rapid transit.

Langen first offered the technology to the cities of Berlin, Munich, and Breslau which all turned it down. However, the towns of Barmen, Elberfeld, and Vohwinkel along the banks of the river Wupper were intrigued by the technology’s ability to connect their communities. The elevated tracks and stations were built between 1897 and 1903; the first track opened in 1901. The railway line is credited with growth of the original cities and their eventual merger into Wuppertal. The Schwebebahn is still in use as a local public transport line, moving 25 million passengers annually, per the 2008 annual report. New rail cars were ordered in 2015, called Generation 15, and the first new car went into service in December 2016.
