One integrated FRMCS concept for the rapid, reliable and scalable deployment of rail-based data infrastructure.
We are VDL Groep and Swietelsky; together, we bring three specialist companies together: VDL NPS, VD Leegte Metaal & Swietelsky Rail.
For the DB, this means:

Implementing FRMCS requires more than just new data masts along the railway. It requires a strong partnership that manages engineering, production and delivery as an integrated whole.
But the real challenge lies in delivering it at scale while keeping the railway available as much as possible.
That’s why our concept moves as much work as possible off the track and into a controlled production environment. Through standardisation, modularity and prefabrication, we create a scalable installation process on the track with:
The task is not only to deploy FRMCS, but to deliver thousands of installations efficiently and predictably without unnecessarily burdening railway operations.
From project-based installation to industrial-scale rollout.

Our approach

Large-scale rollout possible
The Maas Line is the railway connection between Nijmegen and Roermond. Approximately 22,000 passengers use this connection every day, making it one of the busiest regional railway lines in the Netherlands. In the original situation, delays cannot be recovered and disruptions cannot be absorbed, because trains can only pass each other at stations. The provinces of Limburg, North Brabant and Gelderland and the Ministry of Infrastructure and Water Management have therefore decided to electrify the Maas Line together with ProRail. This will make it possible to provide a reliable service on this route.
From 2025 through to 2027, Swietelsky is working hard to make this railway line reliable and sustainable. Where diesel trains still run today, a fully electric connection will soon be in place. And that is precisely where our contribution comes in. We, VD Leegte Metaal, manufacture essential structural components for overhead line systems and support the customer throughout the entire supply chain. From drawings to Just-In-Time deliveries, wherever they are needed along the railway line.
At the end of 2027, the first electric train will run along the upgraded Maaslijn, and VD Leegte Metaal is proud to be part of the journey towards it.
Container transport in the Port of Rotterdam will continue to increase, as will rail freight transport to and from the Maasvlakte. To meet this growth, the Port of Rotterdam Authority, ProRail, the Ministry of Infrastructure and Water Management, and the European Union are investing in sustainable and efficient rail development. Between 2025 and 2027, Swietelsky is delivering the first phase of Maasvlakte Zuid: a new rail yard. We, VD Leegte Metaal, manufacture specialised structural works for the overhead line systems at this rail yard, including cross-braced structures for suspension spans of more than 33 metres.
We provide DB with a controlled, reproducible and scalable FRMCS rollout through one robust, fully integrated supply chain!


At VDL NPS, we are convinced that the key to real success lies in the proud hands of our employees, the driven people who bring our innovative products and projects to life.
As a company, we set the standard thanks to our many years of experience as a project office for public spaces, specialising in planning, project management and mast construction.
Our focus is on specialised construction, product development and planning services for infrastructure, focused on the installation, adaptation and expansion of major nationwide networks for mobile communications, fixed-line networks and e-mobility.
Our goal: Connecting Germany optimally.

Strength through collaboration, the foundation of VDL Groep, the international industrial family business that began 70 years ago as VD Leegte Metaal.
As a forward-thinking supplier, we have been involved in supplying the Dutch Railways/ProRail for decades. We do this from a highly modern factory where efficiency, sustainability and highly automated production are given top priority.
We are keen to establish contact with our customers as early as possible, so that together we can carry out detailed manufacturability studies to achieve the best product. In doing so, we first assess the required production processes in terms of quality, cost efficiency and then sustainability.

Swietelsky builds high-quality railway infrastructure for the sustainable mobility of tomorrow. As a leading railway construction company in the Benelux and Europe, we successfully deliver future-oriented projects in railway construction and the entire railway infrastructure, both nationally and internationally.
Investing in expertise, digitalisation and innovation
In railway construction, we lay the foundations for the fast, safe and comfortable transport of people and goods. Our focus is on solutions that work in practice. We work cost-effectively, to schedule and to the highest standards of execution. To achieve this goal, we continuously invest in expertise, digital processes and the most advanced machinery in the industry.
