Switzerland’s fifth-largest railway station gets an upgrade.

Winterthur railway station is the fifth largest in Switzerland. In order to cope with the constantly growing passenger traffic, Winterthur station has now been modernised. SBB expanded the north underpass (PUN) in the station as part of the national ZEB expansion programme “Future Development of Rail Infrastructure”, and cablex was awarded the contract for implementation of the electrical installations on the platforms and the north passenger underpass (PUN).

In 2020, cablex was awarded the contract for the project “Electrical Installations for the North Passenger Underpass (PUN)”.


Future Development of Rail Infrastructure (ZEB).

Project planning and planning approval for “Future Development of Rail Infrastructure (ZEB)” took place from 2012 to 2016. The scope of the work performed by cablex from 2017 to 2019 included modernising SBB’s own electrical installations under the parking deck and the new platform roof extensions (St.Gallen side).

The following activities were carried out by cablex for the project “North Passenger Underpass (PUN)”:

  • Installation of cable conduits
  • Connection of high- and low-voltage facilities
  • High- and low-voltage installations
  • Installation of emergency and normal lighting facilities
  • Sound facilities for audio system
  • Customer guidance, sector boards, departure monitors
  • Installation of commercial advertising facilities
  • Clocks, WiFi and video installations

 In order to ensure the safety of passenger traffic and project employees and to maintain SBB’s infrastructure, work on the new railway infrastructure took place primarily at night. At the same time, it had to be ensured that daily railway operations could run without interference.

In spring 2020, cablex was able to hand over this complex and high-quality project to SBB. Thanks to the individual technical skills and know-how of the technicians on site, we can look back on a successful, exciting and, above all, accident-free project.

More space – expansion of the north passenger underpass (PUN).

In 2020, cablex was awarded the contract for the project “Electrical Installations for the North Passenger Underpass (PUN)”. The pedestrian underpass, which was 90 years old, was widened from 4.5 metres to 17.5 metres. Running parallel to the underpass, there is also an underground bicycle pass for the city of Winterthur, which connects Rudolfstrasse with Bankstrasse.

For cablex, work on the new passenger underpass began in spring 2021. The PUN connects the platforms via lifts and stairs, and there is also space for six commercial stores and an underground bicycle station. The opening took place on 12 December 2021.

The pedestrian underpass is supplied with energy by two low-voltage main distribution boards and two corresponding transformer stations. The two technical rooms of the low-voltage main distribution boards have been separated from each other, so essentially the energy requirements of SBB Real Estate and SBB Infrastructure are now separate.

The following activities were carried out by cablex for the project “North Passenger Underpass (PUN)”:

  • Project planning and implementation of combined switching equipment for the main distribution boards and sub-distribution boards
  • Project planning and implementation of emergency lighting systems
  • Project planning and implementation of raised floors
  • Project planning and implementation of fire-retardant walls
  • Installation of cable conduits
  • Connection of high- and low-voltage facilities
  • Basic construction work for commercial spaces
  • High- and low-voltage installations
  • UCC and optical fibre installations
  • HVAC installations
  • Lighting installations for emergency and normal lighting
  • Sound facilities for audio system
  • Customer guidance, sector boards, departure monitors and customer traffic measurements
  • Installation of commercial advertising facilities
  • Clocks, WiFi and video installations
  • Access control installations
  • Fire alarm installations
