Jüterbog–Nauen Railway
The Jüterbog–Nauen railway is a line that runs to the west of Berlin through the German state of Brandenburg. It runs from Jüterbog via Treuenbrietzen, Beelitz, Potsdam, Wustermark to Nauen. The line is a part of the Bypass Railway (''Umgehungsbahn''), which was primarily designed to relieve congestion on the railways in Berlin. The Wustermark–Nauen section has been closed, the Golm–Priort section is now a part of the Berlin outer ring and has been rebuilt as a double-track main line. History At the turn of the 20th century, the railway network in Berlin increasingly developed into a bottleneck for the growing freight traffic. A bypass around the capital was considered for strategic military reasons. A line that had been opened from Jüterbog to Treuenbrietzen in 1894 was extended via Potsdam to Nauen on the Berlin–Hamburg Railway (Treuenbrietzen–Beelitz Stadt opened in 1904, Beelitz Stadt–Wildpark in 1908 and Wildpark–Nauen in 1902).

15 KV AC Railway Electrification
Railway electrification systems using at are used on transport railways in Germany, Austria, Switzerland, Sweden, and Norway. The high voltage enables high power transmission with the lower frequency reducing the losses of the traction motors that were available at the beginning of the 20th century. Railway electrification in late 20th century tends to use AC systems which has become the preferred standard for new railway electrifications but extensions of the existing networks are not completely unlikely. In particular, the Gotthard Base Tunnel (opened on 1 June 2016) still uses 15 kV, 16.7 Hz electrification. Due to high conversion costs, it is unlikely that existing systems will be converted to despite the fact that this would reduce the weight of the on-board step-down transformers to one third that of the present devices. History The first electrified railways used series-wound DC motors, first at 600 V and then 1,500 V. Areas with 3 kV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
