Gotthard Base Tunnel, railway equipment, Switzerland (2005 – 2017)
The Gotthard Base Tunnel is one of the core elements of the New Railway Link (NEAT) through the Swiss Alps. Together with the adjacent Ceneri Base Tunnel, it allows trains to pass the Alps on a level-track rail route.
With a length of 57 km, the Gotthard Base Tunnel is one of the longest tunnels worldwide. It consists of a system of two single track tubes connected by crossovers every 325 m.

Lötschberg Base Tunnel, Wallis connection: 4th track St. German – Visp, Switzerland (2005 – 2014)
The track between St. German and Visp will connect the turnout to the Lötschberg base line at St. German with Visp station to the south of the existing Rhone Valley line. Together with the 3rd track, it will allow the simultaneous arrival and departure at Visp station. Furthermore, the Simplon Inter Modal (SIM) concept provides for the overtaking of goods trains with a length of 1,500 m between the Lötschberg Base Tunnel and the Simplon tunnel. The construction of the 4th track will be done during operation and with noise control.

Forchbahn railways – renovation of level crossings, Zurich, Switzerland (2006 – 2014)
Out of the 53 level crossings of the Forchbahn Rehalp-Esslingen, 16 crossings no longer meet the legal requirements and therefore have to be renovated.

SBB resource management, Switzerland (2007)
On the basis of a database, an IT tool was built with which SBB can schedule the large amount of current and planned projects in view of an optimal future resource utilisation.

High-speed connection Switzerland, Neuchātel – Bern line (2005 – 2006)
As part of the extensions of the high-speed railway network (high-speed connections), the intersection at Kerzers station has to be rebuilt to enable trains to pass it at a higher speed. At the moment this intersection can only be passed with a speed of 40 km/h and requires extensive maintenance work.

Gronda Ovest, Italy/Switzerland (2006)
After the opening of the Gotthard Base Tunnel, the Cadenazzo – Luino line will no longer meet the requirements of the goods traffic on the north-south axis towards Novara/Genoa.
A feasibility study was done with 3 variants that should ensure sufficient capacity in the future. The variants were then compared to each other by considering in particular technical, operational and economic criteria.
