Prims Valley Railway
The Prims Valley Railway (german: Primstalbahn) is a partly closed railway line that ran south from Nonnweiler to Primsweiler along the upper reaches of the Prims and then turned to the east and ran via Lebach to Neunkirchen in the German state of the Saarland. The Lebach–Neunkirchen section is still operated. History It was built in three phases. The first section, which was about eight kilometres long, ran from Neunkirchen to Wemmetsweiler (and from there continued south towards Saarbrücken). It was opened on 15 October 1879 and is now part of the Fischbach Valley Railway. A Prussian law authorising the construction of the Hermeskeil–Wemmetsweiler line was approved on 10 May 1890. But construction to Hermeskeil did not begin until 15 April 1894. Because the whole line was being constructed simultaneously, the domestic labour market was soon exhausted and foreign workers from Italy and the Balkans had to be used. On 15 May 1897, the section from Wemmetsweiler to Lebac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
