First Energy-Neutral Station in the Netherlands

Date

23 December 2021

Congratulations, Delft, with Delft Campus station, the first energy-neutral railway station of the Netherlands! The totally renewed station was officially opened on Monday 20th December. We are proud, together with the other parties involved, to contribute to this sustainable new step. The station roof generates all energy needed by the station the year round. Delft Campus paves the way for the sustainable approach of stations in the Netherlands that will be provided with a roof.

The station also has a new entrance and counts two new platforms, and four elevators that make the station better accessible. A new tunnel for cyclists and pedestrians makes it easier to access Delft University.

ProRail expects a huge growth of passengers at Delft Campus station in the years to come. Four trains per hour in each direction pass the station at the moment. This may increase to six trains an hour in 2025. This stimulates sustainable transport between the cities of Leiden and Dordrecht and fits the sustainability ambitions of both Dutch Railways and ProRail.

“It is fantastic to see that we have been able to deliver what we promised at the end of 2018. This makes me proud.” Ben Steehouwer, Project Manager at Strukton

A special roof

What makes the roof of Delft Campus station so special is that the roof itself consists of solar panels. This construction is highly different from laying panels on a roof. The 810 panels have been completely optimised for generating energy. The energy yield will be 200 megawatt per year on average, which is equal to the use of 70 households per year. This is more than enough to compensate the annual energy consumption of the station systems such as elevators, led lighting, public address system, passenger information, ticket checks, etc.

Ready for the future

We were responsible for the construction of the roof, including solar panels and the connection to the power grid. In the design and construction of the station, we have taken future developments into account, such as delivering electricity back to ProRail’s own network or local storage of electricity. The cable pipes under the track bedding are available!

Upgrade Rail Netwerk Rijswijk-Rotterdam

The project is part of the High-Frequency Rail Transport Programme Rijswijk-Rotterdam. We are doubling the tracks between Rijswijk and Delft Campus anticipating the passenger growth. The network will allow for higher train frequencies.

Frequently asked questions

Find answers to frequently asked questions here.

What makes station construction and renovation uniquely complex?

Stations function as multimodal mobility hubs, where pedestrians, cyclists, buses, trams, taxis, trains and commercial activities converge. This density of movements requires careful planning, integrated construction phasing and coordination across many disciplines to maintain safety and accessibility. Station projects often involve platform reconstruction, track works, switches, overhead lines, underground structures, commercial areas and public‑space upgrades all at once

How can construction work continue safely while a station remains operational?

Working in a live station environment requires holistic and precisely synchronised planning. Multidisciplinary teams coordinate construction windows, material deliveries, rail possessions and stakeholder activities to minimise disruption to passengers and train services. This approach is used widely in complex rail environments across Europe, where rail contractors must maintain availability while executing renewal and upgrade works

Why is an integrated, multi‑disciplinary approach essential for modern station projects?

Station upgrades typically combine civil engineering, rail systems, structural works, cable and pipeline installation, telecom systems, travel‑information systems, platform construction, underpasses and bicycle parking. Integrating these disciplines under one coordinated framework reduces delays, prevents spatial conflicts and improves safety. Rail infrastructure specialists with Short Line, Rail‑Civil and engineering units routinely apply this integrated method in complex environments.

How do modern digital tools such as BIM and reality‑capture models improve station construction?

Advanced tools like BIM, 3D reality models, digital asset mapping and rail‑data systems support accurate planning, clash detection and risk reduction. These technologies allow teams to simulate construction stages, coordinate disciplines, and maintain rail operations more effectively. European rail organisations increasingly use digital models to ensure safe, sustainable and predictable delivery of infrastructure upgrades.

How is sustainability incorporated into station upgrades and rail‑infrastructure works?

Sustainable station construction uses circular and recycled materials, optimised soil management and energy‑efficient construction methods. Rail organisations like Strukton also invest in low‑emission equipment, recycled contact wires, and sustainable construction logistics to reduce their carbon footprint. Many civil and rail contractors apply environmental management procedures to lower noise, emissions and waste during work in dense urban stations.

What does sustainability mean in the rail and civil infrastructure sector?

Sustainability in rail and civil engineering focuses on reducing environmental impact across the entire lifecycle of infrastructure. This includes using emission‑free equipment, circular and recycled materials, and designing assets with a longer lifespan and lower maintenance requirements. Reusing structural components—such as circular viaduct beams or recycled copper contact wires for overhead lines—significantly reduces CO₂ emissions while conserving valuable raw materials.

How can CO₂ emissions be reduced in infrastructure projects?

CO₂‑reduction is achieved through a combination of clean construction methods and material innovation. Key strategies include:

  • Deploying zero‑emission machinery such as electric cranes, electric rail‑road vehicles (Krols), electric vans and battery‑powered locomotives.
  • Integrating circular concrete, geopolymer concrete, and recycled materials to lower embodied carbon.
  • Collaborating across the supply chain — from client to contractor to materials supplier — to scale circular and low‑carbon solutions.

These measures not only reduce carbon emissions but help create more resilient, future‑proof infrastructure.
