Historical review:
Until 1997, the line that leads from Spiez to Zweisimmen through the Simmen Valley was owned by the Spiez–Erlenbach–Zweisimmen Railway (SEZ). This railway company had been set up in 1942 through the merger of the Spiez–Erlenbach Railway (SEB) and thew Erlenbach–Zweisimmen Railway (EZB).
In June 1997, the SEZ, along with the Gürbetal–Berne–Schwarzenburg Railway (GBS), the Berne–Neuchâtel Railway (BN) and the Bernese Alpine Rail Society BLS (Berne–Lötschberg–Simplon) merged to become BLS Lötschbergbahn AG.
