The Büren-Weiberg–Thülen section was used in the summer months from 1981 for the operations of museum trains.
This was operated by Dortmund railway enthusiasts as the Westfälische Almetalbahn e. V. (WAB), using an old Dortmund GT4 431 tram together with a generator wagon.
In 2001, the tram set was replaced by railcars.
The association, however, ceased operations on the line several years ago, when the Waldbahn Almetal e. V. took over heritage railway operations on the lower Alme Valley Railway.
It operates two Uerdingen railbuses of class 798.
The tram is now in the Mooskamp Tram Museum (Nahverkehrsmuseum Dortmund) in Dortmund-Nette.

DB Schenker Rail Germany and the Westfälische Landes-Eisenbahn (WLE) operate freight for the Egger company on the section from Brilon Wald via Brilon Stadt to Brilon Egger.
The section between Thülen and Büren, which is leased to RWE AG, is used for the transport of transformers between Buren and the Nehden substation.

In 2007, the track between Brilon Wald and Brilon Egger was restored because the Egger company had to increase its operations and rehabilitation of the line was a condition for expanding its site in Brilon.

In 2008, platform tracks 1 and 4–8 in Brilon Stadt station were demolished and the Brilon Arkaden shopping centre was built on the former railway land.
 Brilon Stadt now retained only two tracks and these were required for freight.
Because of the lack of platforms, the museum trains have operated only as far as Thülen since 2008.

Since 11 December 2011, Regionalbahn services have extended beyond Brilon Wald to Brilon Stadt again.
Its realisation has previously been postponed several times, but at the end of 2008 the Ministry for Construction and Transport of North Rhine-Westphalia agreed to add Brilon Stadt station to its infrastructure financing plan on condition that the Zweckverband SPNV Ruhr-Lippe (association for rail passenger transport of Ruhr-Lippe, ZRL) also funded the line from Brilon Wald to Brilon Stadt.
The ZRL decided on 23 June 2009 to resume scheduled regional services on this section from the timetable change of December 2011.
A central bus station was also established in Brilon Stadt.

A passenger train ran again on the section between Brilon Stadt and Brilon Stadt  for the first time in over 30 years on 10 December 2011.
Since then, through trains have run to and from Dortmund from Monday to Friday.
On Saturdays, Sundays and public holidays trains run to and from Bestwig and Korbach.
