Lauterbrunnen–Grütschalp Aerial Cableway Set for Major Modernization Ahead of New Operating Permit

The Lauterbrunnen–Grütschalp aerial cableway, a key link in the transport chain to Mürren and the Schilthorn region, is preparing for a significant modernization project as it approaches its 20‑year operating milestone.

Commissioned in 2006, the cableway is required under Swiss safety regulations to undergo a comprehensive upgrade before a new operating permit can be issued. Officials say the work is essential to ensure the system can continue to run safely and reliably for the next two decades.

The single-lane aerial cableway can carry 100 persons in its cabin. It climbs 686 metres in altitude and the journey takes 4 minutes.

The aerial cableway can transport up to six tonnes of freight. The mountain station contains a modern transfer station, where freight is moved to the narrow-gauge railway. An average of 5,000 tonnes of materials is transported every year. Depending on the construction activity in Mürren, this quantity can be much higher.

The modernization also offers an opportunity to implement improvements. The new, lightweight aerial cableway will be able to transport 135 people instead of just 100. This will align the cableway's capacity with that of the Grütschalp-Mürren adhesion railway, which was modernized in recent years. The cabin will also be painted in the same color as the adhesion railway and, unlike before, will operate without an attendant. In addition to the cabin, the suspension system and the running gear will also be replaced.

The infrastructure is also being adapted to meet current needs. The platform facilities at both the valley and mountain stations are being renovated. To improve passenger flow and safety, an additional platform, a new escalator, and high platform doors are being installed at the Lauterbrunnen valley station. The ticket office is also being modernized.

The adhesion railway and the aerial tramway already recuperate electricity during their descent. Now, thanks to the installation of an energy storage system, the energy generated during the descent will be stored directly on-site instead of being fed back into the grid. This allows the energy to be used directly during the cable car's ascent, which is both ecologically and economically sound.

During the construction phase, from April 13th to July 10th, 2026 inclusive, operations will be suspended. For travel to Mürren, the connection via Stechelberg is available.

Focus on Safety and Long‑Term Reliability

The modernization will target the cableway’s core mechanical and control systems, many of which have been in continuous use since the line opened. Engineers will replace or overhaul components that have reached the end of their certified service life, bringing the installation up to current technical standards.

Project managers emphasize that the primary goal is to guarantee “safe and trouble‑free operation” well into the 2040s. The Lauterbrunnen–Grütschalp line is a vital public‑transport connection, carrying commuters, schoolchildren, and tourists year‑round, making reliability a top priority.

Opportunity for Improvements

While the upgrade is driven by regulatory requirements, the operators say it also presents a chance to introduce improvements that were not part of the original 2006 design. These may include:

• Enhanced monitoring and automation systems

• More energy‑efficient drive technology

• Updated passenger‑information equipment

• Adjustments to streamline maintenance and reduce downtime

• Specific enhancements will be detailed once engineering assessments are finalized.

The cableway forms the first leg of the well‑known Lauterbrunnen–Mürren mountain transport chain, connecting with the narrow‑gauge Grütschalp–Mürren railway. Any extended closure would have a noticeable impact on local mobility, so planners are working to schedule construction in a way that minimizes disruption.

A detailed project timeline is expected later this year, once technical planning and regulatory reviews are complete. The modernization work will need approval from federal and cantonal authorities before construction can begin.

Local officials say they will provide regular updates to residents and businesses as the project moves forward.
