Austrian national rail operator ÖBB is to carry out rockfall protection work on the Arlberg west ramp in the Bings region. Subsidiary ÖBB-Infrastruktur has begun important preparatory work in the area this month and expects to renew and expand existing rockfall protection in the area from 2023.

“Last year 2021, ÖBB invested around 4 million euros in the upgrading of avalanche and rockfall protection structures on the Arlberg railway line. This year, a further 2 million euros were invested in protective measures, one of the main measures here was avalanche control in the Pfaffentobel area,” a spokesperson for ÖBB-Infrastruktur said.

Upgrade work will focus on the section between Landeck and Bludenz, to ensure sustainable protection of the existing railway facilities. This will include the erection or replacement of around 1,750 linear metres of rockfall protection nets by 2025. Around 12,000 linear meters of anchors will also be drilled into the ground in order to network an area of around 8,000 square metres of rock.

Current preparatory work is expected to run until 2 December 2022 and during this phase ÖBB will deploy a fleet of helicopters to transport wood to key locations in order to complete arrangements as rapidly as possible.

“ÖBB strives to arrange flight times in such a way that the associated increase in noise levels is kept as low as possible. The ÖBB asks for understanding for the necessary work in terms of the safety of railway operations and the residents,” ÖBB-Infrastruktur said.
