This impacted the local economy, and various proposals were brought forward to provide rail service to the Sernf valley.

[1] The line was largely constructed immediately alongside the road, with some narrow street running sections through the villages.

This resulted in a difficult to operate line, with a minimum curve radius of 39 metres (128 ft) and a maximum gradient of 6.8%.

Although the line closed, the operating company survived, changing its name to Autobetrieb Sernftal AG.

One four-wheeled motor coach of 1928 (BDe 2/2 4) is preserved at the Blonay–Chamby museum railway, as is a trailer (B2 13) and a freight car (K31), both of 1905.
