Background

The 4th phase of expansion of the Zurich S-Bahn is the largest expansion of services in the history of the ZVV. Its S-Bahn services plus connecting bus services will be significantly expanded by the end of 2018. This is necessary because the population of the Canton of Zurich is growing, and more and more people are counting on public transport to guarantee their mobility.

The Zurich S-Bahn is the largest S-Bahn system in Switzerland and also the backbone of public transport in Zurich as a place to live and work. It is used by around 175 million passengers each year. Passenger numbers have risen by 180% since the start of the S-Bahn. The network and services have previously been expanded three times. But rapidly rising demand quickly led to bottlenecks again. Particularly during peak hours, overcrowded trains are an everyday experience for commuters on many lines. In order to remedy these bottlenecks in capacity, the S-Bahn will undergo a 4th phase of expansion by the end of 2018. The central element of this expansion is the cross-city link.

25% more services offered

The 4th phase of expansion adds additional S-Bahn lines and routes. The cross-city link at Zurich main station with its four new tracks and around 40 infrastructure projects across the whole canton will enable the introduction of a service every quarter of an hour in the Zurich conurbation and for larger towns in future. The remaining regions in the Zurich Transport Network are connected at half hourly intervals. Direct services between important residential and work areas and accelerated connections from the surrounding areas to the cities of Zurich and Winterthur increase the attractiveness and performance of the S-Bahn. In addition, 50 new double-decker trains that will noticeably ease the overcrowding on many routes are being purchased. In total, capacity will increase by a quarter in the next few years.

Coordination with major national projects

The expansion of capacity is coordinated with major international and regional projects. This exploits synergies and saves costs. In addition to the cross-city link, the following projects are also of key importance.

  • Eastern and Western Switzerland are being connected to the European high-speed train network (high-speed train connection). On the Zurich S-Bahn network, this means expansions between B├╝lach and Schaffhausen and between Zurich and Winterthur.
  • Ultimately, the FDRI (Future Development of Railway Infrastructure) concept aims to improve rail infrastructure in passenger and freight transport. To this end, numerous construction projects in the area of the Zurich S-Bahn, particularly between Zurich and Winterthur, are planned.
