Sieg Railway
The railway crosses the Cologne South Bridge, connecting the West Rhine Railway ("Linke Rheinstrecke"), Cologne South station and the Cologne Eifeltor freight yard on the left (western) side of the Rhine with the Sieg Railway, the Cologne-Frankfurt high-speed railway, the East Rhine Railway ("Rechte Rheinstrecke"), and the marshalling yards of Cologne-Kalk Nord and Gremberg on the right (eastern) side of the Rhine. It was opened on 5 April 1910, disrupted by the bombing of the South Bridge on 6 January 1945, reopened with one track on 3 May 1946 and two tracks in 1950 and electrified on 27 May 1962.
