Overview of construction works on the Feldkirch–Buchs line in 2026

In 2026, ÖBB-Infrastruktur AG will be carrying out extensive construction works along the Feldkirch–Buchs line. The focus will be on the renewal of several bridges, as well as the maintenance and modernisation of existing infrastructure.

The main works will be carried out in a concentrated phase during the line closure from 14 June to 14 October 2026.

Feldkirch–Buchs Bridge Construction Project

Measures already implemented (2024)

  • Renewal of the first bridges in the project section, including the bridge over the Little Liechtenstein Inland Canal
  • Repair of the anti-corrosion protection on all structural elements below track level on the Rhine bridge
  • Renewal of the abutment structure of the Rhine bridge on the Buchs side

These measures form the basis for the intensive main construction phase in 2026.

Main construction phase 2026

  • Concentration of works during the line closure
  • Use of track-laying machinery such as track cranes, rapid track-laying trains and sub-grade improvement machines
  • Establishment of temporary construction and logistics areas
  • In parallel: modernisation of signalling systems and infrastructure

Works in Liechtenstein

  •     Bridge over the Liechtenstein Inland Canal (built in 1929)
  •     Dismantling of the existing structure using rail-mounted cranes and a mobile crane
  •     Transport via the railway track to a nearby site storage area
  •     Dismantling of the steel structure on site
  •     Off-site prefabrication and insertion of the new bridge

Rhine Bridge – Abutment structure (Schaan side)

  •     Renewal of the supporting structure

Corrosion protection for the Rhine Bridge

  •     Comprehensive renewal of the corrosion protection on all steel components
  •     Work carried out within an enclosure to limit emissions and impacts on the surrounding area
  •     Contribution to the long-term preservation of the existing structure

Measures in Switzerland

  •     Bridge over the Werdenberg Inland Canal (built in 1930)
  •     Off-site prefabrication and insertion of the new bridge structure
  •     Diversion for pedestrians and cyclists via Rheinaustraße

Lagerstraße flood bridge (built in 1926)

  •     New construction of the bridge
  •     Diversions for road traffic, pedestrians and cyclists
  •     Setting up of diversions at the start of the road closure

Further measures

  •     Adjustments to technical interfaces
  •     Integration into existing signalling and railway infrastructure

 

Good to know

The line will remain part of the international network whilst construction work is underway. By grouping the work together and coordinating the construction schedule, the impact on rail services will be minimised – whilst at the same time bringing about long-term improvements to the infrastructure through the renewal and modernisation of key facilities.
