History

In 1835 a committee was established in Siegen to promote the construction of a
horse-drawn railway from Siegen to the
Ruhr. The goal was better and faster transport of coal from the Ruhr for smelting in the Siegen area. Iron production in the Siegen country was very important for

. It produced over 23 percent of the country’s total pig iron production and 85 percent of its crude steel production.
During the lengthy approval process, the committee, which was based in Hagen from 1851, changed the proposal to a steam railway, rather than a horse-drawn railway. There was a dispute for a long time about exactly where the line should run. A line from Hagen via the

valley was favoured initially. Later a line running along the Lenne and the Hundem valley was preferred. An interest group from
Olpe wanted the main line to run through the Bigge valley. The committees in both Siegen and Hagen selected a more easterly route through the Hundem valley because it would be shorter and therefore cheaper.
Construction was finally approved in 1856 with a state guarantee of interest payments. Because the line promised economic growth above all for the iron works along it, they took part in financing the line, for instance the Meggen works and the Würdinghausen iron works invested 1,000
thalers each, the Carolinen iron works invested 5,000 thalers and the town of Kirchhundem invested 2,100 thalers. The hoped-for traffic was not achieved at first because charcoal could be brought especially from the

to the Siegen area. The highest point of the railway line between Hagen and Haiger is Welschen Ennest at almost 411 m above sea level.
Line construction

The line was built from 1858 to 1861 under the direction of
Bergisch-Märkische Railway Company and took place with few problems. The construction of tunnels involved the Austrian engineer Franz von Rziha, who had already participated in the construction of the
Semmering railway. Since narrow valleys had to be crossed, the
Borsig company built a special locomotive, class 675, designed for its curves. At first the line was single track, but it was duplicated in 1870. The section from Hagen to Letmathe was opened on 21 March 1859, the Letmathe–

section opened on 17 July 1860 and finally the last part from Altena to Siegen opened on 6 August 1861. The Ruhr-Sieg line had been formally inaugurated on the previous day. In this ceremony a train derailed at Grevenbrück, without any complaints of injury.
Stations were built in all the major towns.
Tudor style stations were built in
Plettenberg, Grevenbrück and Kreuztal, attracting attention as unusual designs for the region (today they are listed monuments). Engine sheds with turntables were commissioned in Letmathe (for 2 locomotives), Altena (6 locos), Altenhundem (6 locos), Kreuztal (2 locos) and Siegen (9 locos). In the late 1870s a depot was built at Finnentrop, close to the branch lines to Olpe (
Bigge Valley Railway) and

Altemhundem was primarily used for heavy freight locomotives for pushing trains up the ramp to Welschen-Ennest station. The depots in Letmathe and Kreuztal lost their importance because of their proximity to the major depots in Hagen and Siegen. Altena depot was abandoned at the beginning of the 20th century. As part of the electrification, Altenhundem depot was abandoned and Finnentrop depot was greatly reduced, as the line is now only used by

on the Ruhr–Sieg line. Traditional stops for express trains were Hagen, Letmathe, Altena, Finnentrop, Lennestadt-Altenhundem, Kreuztal and Hüttental-Weidenau (now called Siegen-Weidenau).
In 1993 long-distance passenger traffic was converted from express trains to
InterRegio trains, stopping regularly only in Hagen, Werdohl, Finnentrop, Altenhundem and Siegen-Weidenau. The long-distance passenger services were made up of several pairs of express train each day and later an Inter-Regio service from Norddeich Mole to Frankfurt, which was discontinued in the summer 2001 timetable.
Current operations
Even today, heavy freight trains need to be pushed by an additional locomotive from Altenhundem to Welschen Ennest. This locomotive then returns to Altenhundem. Before the electrification of the Ruhr–Sieg line almost all southward bound freight trains were pushed up to Welschen Ennest.

Development projects
It is proposed in the Federal Transport Infrastructure Plan to rebuild the Ruhr–Sieg and Dill lines as a line upgraded for high-speed (german: Ausbaustrecke, ABS) by 2015. In recent years, there has been a start to the improvement of the track, such as reconstruction of level crossings and long sections of line, the rationalisation of electronic interlocking equipment and related measures, such as the renewal of turnouts, track, overhead electrification and signals. The enlargement of tunnels, which has been planned for years is now being implemented, allowing the rerouting of some containerised freight from the Rhine lines (
East Rhine and the
West Rhine lines) to the Ruhr-Sieg line.
Moreover, the Ruhr–Sieg line is listed as a "second priority" in the Federal Transport Infrastructure Plan, depending on the growth of demand for freight transport, for such improvements as improving the steep grade on the Altenhundem–Welschen Ennest section.
In the last few years, almost all stations from Altena to Siegen-Weidenau have been modernised under a program of the state of North Rhine-Westphalia, including improvements of access for the disabled. The few stations that have not modernised (including Finnentrop) are intended to be modernised in the coming months and years. Finnentrop station building was demolished for this reason in December 2007. The new station will have same-platform access between trains and buses.
