It was one of the first lines in Germany to be electrified in 1913, together with the Wehra Valley Railway (Wehratalbahn), as a result of its strategic importance and the abundant hydroelectricity available nearby.

Particularly high ticket sales were made at the stations of Lörrach, Stetten, Steinen and Brombach.

[3] Today, the Wiese Valley Railway is part of the network of Deutsche Bahn, but passenger services have been operated since 15 June 2003 by SBB GmbH, the German passenger transport subsidiary of Swiss Federal Railways (SBB).

The modernisation of the stations included the building of 55 cm high platforms (for low floor rolling stock) with a minimum length of 150 metres for coupled Stadler FLIRT electric multiple units.

With the loss of freight traffic, track work was rationalised, particularly at Schopfheim, Lörrach and Maulburg.

All other stations on the Wiese Valley Railway are programmed to have platforms electronic destination indicators installed.
