The power station generated the traction current for the Frankfurt-Offenbacher Trambahn-Gesellschaft (FOTG), which started operation in 1884 as the first electric tram in Germany with overhead lines . The route ran between the endpoints Deutschherrn-Quai near the southern bridgehead of the Old Bridge in Frankfurt-Sachsenhausen and Mathildenplatz in Offenbach . In addition, FOTG was a former municipal energy supplier that supplied the first electricity to companies and private households in Oberrad.

On the eastern edge of Buchrainplatz in Oberrad, a small depot with a workshop, operations office and all other operating buildings was built on the company premises. This included the railway's own coal-fired power station to generate the electricity for running the trains on the line.

history

A separate power plant had to be built for the electrical operation of the FOTG, since at that time there was no other possibility of power supply for its route in Oberrad or the surrounding area. The railroad power station was located about halfway down the track in a factory building from brick on the premises of FOTG on the eastern side of the square Buchrain. The energy source in the power plant's machine house was a steam engine . With the combustion heat of 2.5 tons (50 quintals ) of coal per day, steam was generated in three boilers, each with seven individual boilers , supplied by the boiler forge and shipyard Ewald Berninghaus in Duisburg . The steam engine drove a flywheel with a diameter of 5 m. The rotating movement of the flywheel was used with a transmission belt to drive four electrical generators with a total output of 190 kW . With the electrical power obtained in this way, a maximum of 12 railcars could have been operated at the same time. If the steam boiler failed, a rented locomobile was used to drive the drive belts.

The power plant was a popular excursion destination for the population , as one could admire the movements of the flywheel, various gears and the transmission belt through the windows of the machine hall . The power station was in operation until the FOTG was completely taken over by the Frankfurt tram in 1906. The factory hall in which the power plant was originally located was damaged during the air raids on Frankfurt am Main during World War II . After the war, the remaining parts of the building were demolished. Today the community center SAALBAU Depot Oberrad stands in front of the former location of the FOTG company premises on the eastern edge of Buchrainplatz .

aftermath

From 1888, the electricity generated by the power plant was used for the newly installed light bulbs next to the tram line . In addition, the excess capacity was offered to businesses and households in Oberrad . The FOTG power station thus also became the first power station for Oberrad. Ultimately, this connection was groundbreaking for the combined task of municipal energy supply companies , which operated power plants for generating electricity and electric railways for local public transport . In Frankfurt, this was the last of the Stadtwerke Frankfurt am Main , the later legal successor of FOTG. Today, the tasks of municipal sponsorship in the field of energy generation are performed by Mainova AG and in the field of transport companies by Stadtwerke Verkehrsgesellschaft Frankfurt am Main (VGF).

Under the umbrella of Siemens AG, there are still business areas that deal with the manufacture of power generation products ( Power Generation Division of Siemens Energy ) and rail transport technology ( Siemens Mobility ).
