The GBS was then part of an operating group led by the Bern–Lötschberg–Simplon railway (Bern-Lötschberg-Simplon-Bahn, BLS). The four group companies merged in 1997 to form the BLS Lötschberg Railway, which in turn merged with the Regionalverkehr Mittelland (RM) in 2006 to form BLS AG, which now owns the former BSB line.
