Rotterdam's railway gets new signalling system after a turbulent year

ROTTERDAM, 10 November 2026 | After a year marked by major train disruptions, a devastating cable fire and even an incident of deliberate arson, Rotterdam's railway network has received some welcome news. A new digital train signalling system has successfully entered service around Rotterdam and Schiedam, replacing technology that had been in use for nearly thirty years.

The changeover was completed during the weekend of 7 and 8 November, when Rotterdam Centraal was temporarily closed to train traffic. According to rail infrastructure manager ProRail, the new system should make maintaining the network easier and reduce the likelihood that future signalling work will require shutting down the entire Rotterdam rail hub.

It's the culmination of years of engineering, preparation and testing, much of it taking place out of sight of the thousands of passengers who use Rotterdam's railway connections every day.

A summer of railway disruption

For Rotterdam train passengers, the importance of reliable railway infrastructure has been painfully clear this year.

On 29 June 2026, a fire in a cable duct near Rotterdam Stadion caused extensive damage to the railway's electrical and signalling infrastructure. The disruption brought train services between Rotterdam and destinations to the south, including Dordrecht and Breda, to a standstill.

More than 200 cables had to be repaired or replaced, a painstaking task made even more complicated because the fire had destroyed many of the identification labels attached to them.

The disruption lasted until 7 July, leaving passengers dependent on replacement transport and forcing freight operators to find alternative routes.

ProRail subsequently explained that the fire resulted from a defective overhead-line power cable located beneath the cable duct. An electrical fault had ignited the surrounding infrastructure, triggering a much larger failure.

Then came an incident of deliberate arson

Rotterdam's railway infrastructure suffered another serious setback on 10 October. 

This time, the disruption was not simply the result of an electrical fault. Near Delfshaven, a technical room had been forcibly opened and a fire deliberately started, damaging railway cables and installations. Train services between Rotterdam Centraal and Delft Campus were disrupted for much of the weekend while repairs were carried out. Police opened an investigation into the arson.

The incidents were separate, with different reported causes. There is no evidence that the June fire was deliberate, nor that either incident was connected to the new signalling project.

They nevertheless illustrate how vulnerable an extensive railway network can be when essential infrastructure is damaged.

Cybersecurity has also become a growing national concern. In its latest cybersecurity assessment, published on 6 November, the Dutch National Coordinator for Security and Counterterrorism warned that cyber threats are developing faster than the ability of many organisations to defend themselves.

These are different kinds of risks, but they raise a similar question: how do we keep essential services dependable in a world where both accidents and deliberate interference can cause widespread disruption?

What has actually changed beneath Rotterdam's tracks?

The newly commissioned system is known as an IXL interlocking. Although the terminology sounds complicated, its purpose is straightforward. It controls railway signals and points, monitors where trains are located and ensures that trains can only move through the railway network when their routes are safe. Think of it as one of the railway's essential traffic-control systems, coordinating the infrastructure that allows trains to move safely through busy junctions.

Replacing it was no small undertaking. Over several years, engineers installed and tested around 10,000 switches, built new connections and adapted technical facilities while keeping the existing system operational wherever possible. The new installation was constructed alongside the ageing system, allowing extensive testing before the final changeover.

During the first weekend of November, engineers switched the network over to the new technology, retiring the previous installation after nearly three decades of service.

What does this mean for Rotterdam passengers?

Most travellers won't notice any immediate difference. Trains will look the same, signals will continue doing their jobs and the station experience will remain familiar. The most important improvements are behind the scenes.

Under the new arrangement, the signalling infrastructure is divided into smaller operational sections. According to ProRail, this should make it possible to carry out certain future signalling works without taking the entire Rotterdam railway area out of service. That is particularly valuable at Rotterdam Centraal, where local, intercity, international and high-speed services meet.

The upgrade should also help keep the infrastructure maintainable and reliable as the railway network continues to accommodate large numbers of passenger and freight trains.

More railway work is still to come

Although the new signalling system is operational, the overall modernisation project has not yet been completed. Engineers still need to remove the old installation, dismantle temporary facilities and finish work in technical rooms. These final activities are scheduled to continue throughout 2027.

There is also another significant period of disruption approaching.

From 29 November to 7 December 2026, no trains are scheduled to operate between Rotterdam Zuid and Barendrecht because of further infrastructure work. NS is arranging replacement bus services.

Passengers travelling through Rotterdam during this period should check their journeys in advance using the NS journey planner.

Further information about the modernisation programme is available on ProRail's Rotterdam railway signalling project page.

A welcome step towards a more reliable railway

The successful switch was carried out by engineering company Movares on behalf of ProRail, working with Van Gelder Rail and other specialist partners.

It's not the sort of achievement that usually attracts the same attention as the opening of a new station or railway line. There is no spectacular new building to admire, and passengers may never see most of the equipment involved.

But after a year in which relatively small failures have demonstrated just how quickly a railway network can grind to a halt, improvements to the technology keeping trains moving deserve recognition.

We shouldn't expect every delay or disruption to disappear overnight. Rotterdam's railway infrastructure remains complex, heavily used and dependent on much more than its signalling technology.

Still, the successful replacement of a critical system is an encouraging step towards a railway that is better equipped for the years ahead.
