Strukton to install ERTMS in the North

Expertise

Train Protection

Strukton is going to roll-out ERTMS on the Leeuwarden – Harlingen Harbour section on behalf of ProRail as part of the ERTMS Northern Lines project in the Netherlands. BAM was awarded the contract for the same work on the Leeuwarden – Stavoren section. During the roll-out, we will gain experience with the latest version of ERTMS together with the parties involved. Preparations are in full swing and implementation will start in 2026.

What are we going to do?

We are going to install the ERTMS infrastructure on the Leeuwarden – Harlingen Harbour section. This includes new cables, axle counters and balises in the track. We are installing ERTMS as a replacement for the existing train safety system (ATB). After the commissioning of ERTMS, we will immediately remove the old train safety system.

ERTMS in the north of the Netherlands

The Leeuwarden – Harlingen Harbour section is part of the test strategy of the Netherlands ERTMS programme. This section of track will host testing of the latest version of ERTMS with converted track, converted trains, new systems and trained personnel. Ben van Schijndel, Strukton Rail’s ERTMS programme manager: “It is fantastic to be so intensively involved in this first line and to be fully involved in the test strategy.”

When the tests between Leeuwarden and Harlingen Harbour are successfully completed, BAM Railinfra Nederland will install ERTMS between Leeuwarden and Stavoren. This will be followed by the construction of ERTMS on the rest of the Northern lines. The ERTMS Northern Lines project consists of a total of six sections of track and the Groningen and Leeuwarden stations. The project is a collaboration between ProRail, Arriva, the Provinces of Fryslân and Groningen and the ERTMS Programme Directorate.

More ERTMS projects in the Netherlands

In November, BAM Infra Nederland and Strukton were also awarded the contract for the construction of ERTMS between Kijfhoek and the Belgian border. This work will start at the end of 2025 and will continue until 2028.

Strukton’s experience with ERTMS

Strukton already has extensive experience with the roll-out of ERTMS. We constructed the Betuweroute, including ERTMS, rolled out ERTMS on the port railway line and in Denmark we are the infrastructure party that is rolling out ERTMS on the Fjernbane in a consortium with Thales. In recent years, Strukton has been one of ProRail’s innovation partners in the ASAP project to accelerate the ERTMS Programme. Innovations that Strukton developed within ASAP are the ERTMS reality model and the ERTMS trackbot. These innovations will play an important role in the roll-out between Leeuwarden and Harlingen Haven.

Frequently asked questions

Find answers to frequently asked questions here.

What is the innovative ERTMS Trackbot used in digital rail modernisation?

The ERTMS Trackbot is Strukton’s robotic solution designed to mount balises and axle counters efficiently and safely on sleepers and rails—components essential for ETCS operation. With tens of thousands of balises and over twenty thousand axle counters required for ERTMS rollout in the Netherlands alone, the Trackbot automates this repetitive, physically demanding work and helps speed up deployment.

What is train protection?

Train protection refers to the systems and processes that ensure trains operate safely. The systems detect train locations, manage movement authorities and intervene automatically—typically by applying the brakes—if a train exceeds safe speed limits or passes a signal at danger. Train protection therefore prevents collisions, derailments and other hazardous situations.

Which train protection systems are used in the Netherlands?

The Netherlands primarily uses Automatische Treinbeïnvloeding (ATB), a national automatic train control system developed to enforce speed limits and intervene when drivers fail to respond to signals. ATB monitors speed and automatically applies the brakes when required. The Netherlands is also transitioning to ERTMS, Europe’s digital signalling and train control standard that will gradually replace older systems to improve safety, capacity and interoperability.

What experience does Strukton have with ERTMS?

Strukton has extensive expertise in designing, installing and integrating ERTMS on major European corridors. Our experience includes deployments on the Betuweroute and the Amsterdam–Utrecht line, as well as a large‑scale ERTMS programme in Denmark. We are also rolling out ERTMS in the Dutch province of Friesland and on the Rotterdam–Belgian border route. Our in‑house innovations help accelerate implementation and support Europe’s transition to a fully interoperable rail  network.

What is ERTMS?

The European Rail Traffic Management System (ERTMS) is Europe’s standardised digital signalling and automatic train protection system. It uses ETCS cab signalling to provide real‑time speed and movement information directly to the driver, supported by GSM‑R radio communication. ERTMS increases rail capacity, enhances safety and enables seamless cross‑border operations, making it central to the modernisation of Europe’s railway network
