Due to construction work in the Hauenstein Base Tunnel with partial single-track operation for five weeks, various trains are canceled and others are rerouted via the old, single-track Hauenstein line from Olten via Läufelfingen to Sissach. The S9 train service on this line is cancelled and replaced by an half hourly bus service. The “Cargo-Beamer” train 43756 from Domodossola via Brig-Lötschberg base tunnel-Thun-Burgdorf-Olten to Basel-Kaldenkirchen/Germany, crosses the 25 meter high Rümlinger viaduct (built 1856 to 1858) between Buckten and Sommerau, pulled by the Re 465 # 012 and the Bombardier TRAXX F140 AC1 Re 485 # 015 from BLS Cargo.
