Groningen is one of the busiest stations in the Netherlands, with around 33,000 passengers travelling to and from the station every day – a number expected to grow to 44,000 by 2030. To prepare for this future, the station and its surroundings are undergoing a major transformation.
Strukton is delivering this complex project on behalf of railway manager ProRail, working closely with the Province and Municipality of Groningen. Multiple Strukton companies are collaborating with external partners to realise an integrated solution that combines civil engineering, rail infrastructure, and environmental expertise.
The works include creating a new underground passenger concourse, a large bicycle storage facility, extended and additional platforms, a new bus station and facilities, as well as tunnels for buses and cyclists. These elements are designed to improve accessibility, capacity, and connectivity for all travellers.

Working With the Shop Open
One of the defining features of the project is the construction of a massive excavation for the concourse and bicycle storage, built beneath the existing station while trains continue to run. This “working with the shop open” approach requires meticulous planning and coordination to keep the station operational and safe for passengers throughout the works.

The Goal
When complete, Groningen Main Station will offer:
- A modern underground passage connecting the station to a new city park
- Increased rail capacity, enabling more destinations across the region and northern Netherlands
- Improved facilities for buses, cyclists, and pedestrians
