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 service on this line is cancelled and replaced by an half hourly bus service. Northbound intermodal train 43472 from Mortara/Italy via Domodossola-Simplon-Lötschberg base tunnel-Basel to Rotterdam Waalhaven/Netherlands is crossing the 25 meter high and 128 meter long Rümlinger viaduct, which is bridging the Häfelfinger valley and was built from 1856 to 1858 by the Schweizerische Centralbahn (SCB)/Swiss central railway. Pulling are Siemens ES 64 F4 Re 474 # 017 of SBB Cargo International and Siemens "Vectron" 193 # 473 of the LokRoll leasing company, rented to SBB Cargo International, in multiple control.
