Alstom delivers ERTMS signalling system on the Iron Ore Line, in Sweden

• Alstom has delivered European Rail Traffic Management System (ERTMS) on the Iron Ore Line (known in Swedish as ‘Malmbanan’), marking the first deployment outside of pilot lines in Sweden.
• The delivery includes a phased transition via Automatic Train Control (ATC) followed by ERTMS, covering key control areas such as Kiruna, Gällivare, Linaälv and part of Björkliden.
• The project strengthens safety, reliability, and modernisation of one of Sweden’s most strategically important rail corridors.

Alstom, a global leader in smart and sustainable mobility, has delivered and commissioned ERTMS on the Iron Ore Line (known in Swedish as ‘Malmbanan’), one of Sweden’s most critical rail lines for freight transport. This marks the first deployment of the new European signalling standard outside of Sweden’s ERTMS pilot lines, bringing increased reliability and less need for maintenance to this strategically vital route.

The modernisation of Malmbanan’s signalling was carried out in close partnership with Trafikverket (the Swedish Transport Administration). The delivery has taken place in two key stages: initially through an intermediate upgrade using ATC and then transitioning to ERTMS – now in operation in the control areas of Linaälv, Gällivare, Kiruna and most recently part of Björkliden.

The project includes system design, development, supply of equipment, testing, commissioning, and training. The solution was primarily developed by Alstom’s engineering teams based in Stockholm and Hässleholm, drawing on their extensive knowledge of Malmbanan’s existing signalling infrastructure and operational context.

“We are pleased to see ERTMS now operational on Malmbanan – the first line outside the pilot lines to enter deployment. It is a pride for us to support Trafikverket in this rollout to modernize the railway” says Maria Signal-Martebo, Managing Director, Alstom Sweden. “This delivery was possible thanks to our local presence with deep knowledge in signalling systems and operations conditions in Sweden.”

The digital signalling solution deployed on Malmbanan is part of Alstom’s comprehensive and world-leading portfolio for mainline and regional railways. It incorporates Onvia Control for ERTMS and Onvia Lock for interlocking, both tailored to meet the specific operational needs of Sweden’s northernmost railway. The legacy ATC and the new signalling system are seamlessly managed through Alstom’s Onvia Vision traffic management platform. This unified environment has streamlined the transition and supports efficient, and modern railway operations.

Local insight, global expertise

Key success factors in the project included strong collaboration with Trafikverket, good knowledge in Malmbanan’s operational environment, and valuable insights gained from Alstom’s previous ERTMS deliveries on the Ådalen Line (also known in Swedish as ‘Ådalsbanan’) and on the Bothnia Line (also known in Swedish as ‘Botniabanan’).

Alstom is also the market leader in rail services, supporting customers over the entire asset lifecycle with the broadest portfolio of signalling services solutions. Alstom’s digital solutions deliver the highest availability, reliability, and performance for operator’s rail assets, with integrated, modular, and secure services to optimize operations and maintenance activities, and enhance passenger experience.

Alstom is the largest supplier to the Swedish train market, with over a thousand trains delivered to the Swedish railways and several major maintenance contracts. Alstom also leads the implementation of the European Railway Traffic Management System (ERTMS) signalling system in Sweden, both onboard and along the tracks.
