European Rail Traffic Management System (ERTMS) strengthening performance, reliability and availability across the Norwegian rail network
28 January 2026 – Alstom, global leader in smart and sustainable mobility, has reached a significant milestone in Norway’s digital rail transformation with the upgrade of its 100th train to onboard ERTMS signalling. Alstom is part of one of Europe’s most ambitious signalling programmes, with a mission ultimately covering the equipment of more than 350 trains. This achievement strengthens the foundation for higher capacity, improved punctuality and long‑term interoperability across the Norwegian rail network. Key stakeholders were gathered at Alstom’s Grorud depot in the greater Oslo area to mark the milestone.
"Passing the 100‑train mark shows how far we have come on this journey. ERTMS will help boost track capacity, raise punctuality and save money by reducing wayside equipment."
“Passing the 100‑train mark shows how far we have come on this journey. ERTMS will help boost track capacity, raise punctuality and save money by reducing wayside equipment. None of this would be possible without the outstanding commitment of our teams, who are driving this transformation every day, says Jörg Nikutta, MD Alstom Denmark & Norway.
Delivering the digital railway for Norway
The ERTMS signalling system (European Rail Traffic Management System) strengthens performance, reliability and availability across the Norwegian rail network. Alstom holds multiple contracts to equip the entire Norwegian railway fleet with ERTMS on-board train control solutions.
The upgrade and production work is carried in Norway at Alstom’s facilities in the Grorud Depot near Oslo and the Marienborg Depot near Trondheim, where teams are upgrading the software and hardware for signalling on a broad range of rolling stock. The work is done in collaboration with various players on the Norwegian railway market: Bane NOR, Norske Tog, Vy Group, SJ Norge as well as freight operators.
Advanced, climate‑ready technology
The ERTMS upgrade programme covers all passenger trains, locomotives, and track maintenance machines, fitted with a next‑generation odometry system using satellite positioning—engineered to perform reliably in Norway’s demanding climatic conditions. Two fleets are already fully completed: heavy‑duty maintenance machine vehicles and rescue locomotives, both owned and operated by Bane NOR.
The system upgrade is progressing at strong pace, currently with 3-4 passenger trains per month. These assets are essential for both passenger and freight services, ensuring Norway’s rail operations continue to run safely and efficiently during and after the ERTMS transition.
Alstom’s Onvia Cab system is a modern, interoperable onboard signalling solution designed to integrate seamlessly into both new and existing trains. Alstom brings proven global experience to the Norwegian programme, having delivered more than 300 onboard digital‑signalling projects in over 40 countries. This milestone moves Norway closer to a fully digital, higher‑capacity railway, ready for future interoperability with European rail networks.
