The originally approximately eight-kilometer-long railway line was opened by the former Bern-Zollikofen-Bahn on 13 July 1912.

It is now 5.35 kilometres (3.32 mi) long as a result of the line being rebuilt in the city of Bern in 1965 and the closure of the 1.16 kilometres (0.72 mi)-long Zollikofen–Unterzollikofen section in 1974.

All three routes have been operated since 1 January 1984 by Regionalverkehr Bern-Solothurn (RBS) and are integrated into the Bern S-Bahn.

Worblaufen is its operating centre and is also the location of a depot and a workshop.

By contrast, the current terminus at Unterzollikofen has only one dead-end track with a single platform edge.
