Since the Prussian Province of Hohenzollern (Hohenzollern Lands) was an elongated territory partly surrounded by the Kingdom of Württemberg, the line of the Royal Württemberg State Railways (Königlich Württembergischen Staats-Eisenbahnen) at this time only used the shortest route through this "foreign" area and only served the two district towns of Hechingen (from 1869) and Sigmaringen (from 1878).

The Schlatt, Killer, Burladingen West and Gammertingen Europastraße stations have been established as request stops.

The current transport contract with SWEG, which has been the legal successor to the Hohenzollerische Landesbahn since the 2018 merger, runs until 2025.

[2] Until the timetable change in 2020, Regio-Shuttle 1 diesel multiple units in the red-beige livery of the Hohenzollerische Landesbahn operated on the line.

Now Lint 54 sets in the Baden-Württemberg state livery are used for passenger services.
