History
Formation
The Sieg railway is the western section of the
Deutz–Gießen railway

(''Deutz-Gießener Eisenbahn'', DGE) as far as Betzdorf and the line from there to Siegen, which was originally opened as a branch line on 10 January 1861.
From the time of the building of a line, a direct connection was proposed between Siegen and Haiger, which was eventually opened in 1915. This shortened the connection between Siegen and Dillenburg by about , leading to a shift of traffic from the old line (now known as the
Heller Valley Railway), which subsequently usually ran via Siegen and Haiger.
Further development
The Sieg flood of 1909 destroyed many bridges, including railway bridges, such as at Herchen, which had to be rebuilt. In 1914, numerous special trains were used to carry German troops to their deployment area in the

many bridges over the Sieg were destroyed by the retreating German Army. Many of these bridges were rebuilt with single-track only. In 1991, the second track was restored on the Troisdorf–Siegburg section for
S-Bahn operations. There are still single-track sections between Blankenberg and Merten () and between Schladern and Rosbach (). On 18 February 1956, there was a serious train accident near the town of Bülgenauel. Two people were killed and 15 injured in a collision of a freight train and an express passenger train, caused by human error.
In 1962 was the first section of the Sieg line from Cologne to Troisdorf was electrified, together with the
Right Rhine line. The rest of the Sieg line was electrified in 1980. The once extensive freight traffic on the line has declined sharply.
