Only 2.3 kilometres long, the link from Deusen junction to Buschstraße junction is one of the shortest railways in Dortmund. It was built in 1942 to provide a direct extension of the bypass to provide a connection from the important freight yards in the north of the Dortmund urban area to the yards in the southwest of Dortmund.[11]
The direct link was used to connect several lines to the Dortmund-Huckarde Süd freight yard, including the Dortmund Süd–Bodelschwingh railway opened in 1878 by the Royal Westphalian Railway Company[5] and the connection to Rahm on the Duisburg-Ruhrort–Dortmund railway.
In 1965, the stretch from Huckarde Süd to Deusen was electrified,[11] but three years later the two remaining branches to Rahm and Bodelschwingh were closed, causing Buschstraße junction to be closed.
Buschstraße junction was re-established with the conversion of the line from Dortmund-Huckarde to Dortmund-Mengede for the S-Bahn in 1986.[12] However, only one set of points was re-established, so trains from Deusen must run from the junction to Huckarde Süd Railway Station on the left track, opposite the normal direction of travel. Shortly after the junction the line becomes two-track and the rest of the line is duplicated.
About 1.2 km later there is another peculiarity, where the freight line crosses the line U 47 of the Dortmund Stadtbahn at ground level with the two lines are electrified with different current systems. A crossing guard is in charge here on the two lines for ensuring the safety of operations and Stadtbahn services are controlled by signals and also prevented with barriers from crossing the freight line. To avoid interference the overhead wire of the track which is not occupied is removed at the crossing.[13] For a long time there has been consideration of removing this intersection by building an overpass or underpass for the Stadtbahn line, but the construction of such a construction project has not yet been authorised.
After crossing the Emscherallee in the grounds of the former Hansa coking plant, the line reaches Deusen junction on the line from Mengede to Obereving. Despite its electrification, the line does not play a prominent role for freight transport; many trains from or towards Bochum and Witten go via Wanne-Eickel, but only a few trains a day run on this line.
