To enhance safety and efficiency, the Bern-Lötschberg-Simplon Railway (BLS) has unveiled plans for an extensive renovation project on the railway line between Solothurn and Oberdorf. Scheduled to commence on May 21st and run until July 5th, the project aims to upgrade both the track infrastructure and overhead lines, with a particular focus on the Geisslochviadukt bridge.

During the seven-week period, commuters and travellers between Solothurn and Oberdorf will experience disruptions as train services will be replaced by buses. The replacement buses will ensure continued connectivity while the essential maintenance work is underway. Departure times for these buses can be accessed through the online timetable provided on the BLS website.

At the heart of the renovation project lies the Geisslochviadukt bridge, where new steel bridges will be installed to enhance structural integrity and ensure long-term safety. Additionally, various sections of the railway line will undergo extensive upgrades, including the renewal of rails, sleepers, and ballast. The complete replacement of the overhead line infrastructure is also planned to further modernize the route.

To accommodate the ambitious renovation schedule, BLS has outlined a strategy that includes night-time work and weekend shifts, ensuring minimal disruption to regular daytime services. These measures are designed to expedite the completion of the project and allow for the timely reopening of the railway line on July 6th.

In parallel with the renovation efforts, ongoing rehabilitation works in the Weissensteintunnel will continue as scheduled. The tunnel, a critical link in the railway network, will remain closed to train traffic until its renovation is completed in December 2025.

As part of its commitment to transparency and community engagement, BLS will host an Open Construction Site Day at the Geisslochviadukt on Sunday, June 16th. Members of the public are invited to participate in guided tours of the construction site, offering a unique opportunity to witness the historic renovation efforts firsthand.

The renovation project represents a significant investment in the region’s infrastructure and underscores BLS’s dedication to ensuring the long-term reliability and safety of its railway network. By modernizing key elements of the Solothurn-Oberdorf line, BLS aims to provide passengers with an improved travel experience while maintaining the highest standards of safety and efficiency.
