  • Major project to boost rail capacity in the Zurich area in the long term

    Major project to boost rail capacity in the Zurich area in the long term

    According to a press release, SBB has begun work on upgrading the line between Zurich and Winterthur to four tracks throughout. As part of the ‘MehrSpur Zurich-Winterthur’ project, SBB is constructing a new tunnel, upgrading several stations and carrying out further improvements.

    SBB and the construction firms involved have now started work on upgrading the stations at Wallisellen, Dietlikon, Bassersdorf and Winterthur Töss. This includes widening platforms, constructing new and modified underpasses, and building footbridges and bridges. Work in Bassersdorf is due to be completed by 2030, in Wallisellen and Dietlikon by 2031, and in Töss by 2034.

    The Brütten Tunnel is set to be 9 kilometres long. Tunnel boring is scheduled to begin in 2029, with the tunnel due to open in 2037.

    The expansion is expected to cost a total of 3.3 billion Swiss francs. This major project, together with other initiatives such as the expansion of Zurich Stadelhofen station, is set to significantly improve rail services in the Greater Zurich area.

  • New double-track line relieves congestion on the route between Zurich and Winterthur

    SBB has commissioned a consortium consisting of the construction companies Implenia from Opfikon and Marti from Zurich to build a new double-track line. As part of the Zurich-Winterthur multi-track project, the Swiss Confederation and SBB are planning to build a new line and expand the stations in Dietlikon, Bassersdorf, Wallisellen and Winterthur Töss. According to a statement, Implenia and Marti will each take on 50 per cent of the construction of five of the six lots in the project. The total contract is worth around CHF 1.7 billion, with Implenia’s share amounting to around CHF 830 million. The project is expected to take around ten years to complete.

    As part of the project, Implenia and Marti will take on the construction of the Brüttener Tunnel (lot 240), the Winterthur section (lots 140 and 141), the Dietlikon section (lot 340) and the Wallisellen section (lot 540). The new double-track line through the Brüttener Tunnel is intended to eliminate the 8.3-kilometre capacity bottleneck in the rail network between Zurich and Winterthur. Part of the bottleneck is a branch line towards Zurich Airport. The underground double-track expansion will involve the construction of a single-track tunnel with a diameter of around ten metres for each direction of travel.

    According to the announcement, the infrastructure project is geared towards the mobility needs of future generations and is therefore in line with Implenia’s strategy. “We are delighted that Implenia, together with our consortium partner Marti, will be able to contribute our many years of experience and comprehensive expertise in infrastructure construction to make this important section fit for increasing frequencies and future requirements,” said Implenia CEO Jens Vollmar in the press release.

  • Green light for railway extension between Zurich and Winterthur

    Green light for railway extension between Zurich and Winterthur

    According to a press release, the Federal Office of Transport has granted planning permission for the expansion of the link between Zurich and Winterthur. A nine-kilometre double-track tunnel is to be built for this purpose, which will be reached in the south with two access routes from Bassersdorf and Dietlikon. In the north, it ends at Tössmühle in Winterthur. At the same time, the railway stations in Winterthur-Töss, Dietlikon, Bassersdorf and Wallisellen are to be rebuilt and extended.

    The expansion will widen the current bottleneck through Effretikon and Kemptthal to four tracks throughout. This will shorten journey times and expand the range of regional connections in particular.

    The costs are estimated at CHF 3.3 billion in 2014 prices. The expansion is part of the 2035 railway expansion phase approved by the Federal Parliament in 2019.

    The planning approval can be appealed to the Federal Administrative Court within 30 days. Otherwise, SBB can determine the definitive expansion programme and start the preparatory work at the beginning of 2026.
