Frankfurt-Sindlingen station is a suburban station on the network of the Rhine-Main S-Bahn in the district of Sindlingen in the German city of Frankfurt. The station is classified by Deutsche Bahn as a category 5 station.LocationThe S-Bahn station is located in the centre of the Frankfurt district of Sindlingen in the state of Hesse. The station is located where the main street of the suburb, Sindlinger Bahnstraße, passes under the Taunus Railway (Taunus-Eisenbahn). To the north of the platform is a municipal building called the Haus Sindlingen ("Sindlingen House"), which is used as a community centre and library. It was used for a trial of members of the Red Army Faction, including Astrid Proll, in 1973–74.HistoryIn the 19th century the northern and central parts of Sindlingen were undeveloped. The rural town had just 750 inhabitants. The Taunus Railway, which was opened between Höchst and Hattersheim on 24 November 1839, ran through this area and crossed the highway to Zeilsheim (now called Sindlinger Bahnstraße, literally "Sindlingen railway street"). The progressive industrialisation of the area, in particular the growth of the factories of Hoechst AG, caused considerable population growth in Sindlingen and the surrounding villages. Eventually stations would be built in the district on the Taunus Railway and the Main-Lahn Railway, which was opened a little further north in 1877, although the northern station was not completed for more than a century.
