Leipzig-Engelsdorf–Leipzig-Connewitz Railway
The Leipzig-Engelsdorf–Leipzig-Connewitz railway is a double-track, electrified main line in the Leipzig area in the German state of Saxony. It was originally built as part of the Leipzig Freight Ring (''Leipziger Güterring''), but since December 2013 it has also been mainly used for the operations of the S-Bahn Mitteldeutschland. At the former Tabakmühle junction the line now transitions into the Tabakmühle junction–Leipzig Bayer Bf railway and the approximately 800 m-long section from Tabakmühle junction to the beginning of Leipzig-Connewitz station is closed. History During the reconstruction of the Leipzig railway node after the turn of the twentieth century, including, among other things, the construction of the central Leipzig passenger station and the creation of a Freight Ring, the Royal Saxon State Railways built the Engelsdorf–Leipzig Stötteritz link. The line was intended to connect the former Stötteritz halt, which developed into an important suburban p ...

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 ...
