🛑 Key Takeaways:

Alstom has delivered the 100th ERTMS-retrofitted train for Norway’s national signaling program, which targets a total of over 350 vehicles.
The project is progressing at a rate of 3-4 trains per month, using Alstom’s Onvia Cab platform with a unique satellite-based positioning system.
This milestone advances Norway’s strategy to increase network capacity and interoperability while lowering long-term maintenance costs by reducing trackside equipment.

OSLO, NORWAY – Alstom has reached a key production milestone in Norway’s national digital railway program with the delivery of its 100th train equipped with the European Rail Traffic Management System (ERTMS). The project, one of Europe’s most extensive signaling upgrades, aims to retrofit Alstom’s on-board system across a fleet of more than 350 passenger, freight, and maintenance vehicles.

Category	Specification / Detail
Project	Norway ERTMS National Implementation
Total Scope	Over 350 rail vehicles
Current Status	100 vehicles delivered; 2 fleets fully upgraded (Bane NOR)
On-board System	Alstom Onvia Cab ERTMS Platform
Production Rate	3-4 modernized trains per month
Key Stakeholders	Alstom, Bane NOR, Norske Tog, Vy, SJ Norge, freight operators

Operational & Technical Details

The retrofitting work is performed entirely within Norway. Alstom’s facilities in Grorud (Oslo) and Marienborg (Trondheim) handle the installation and testing. The core technology is Alstom’s Onvia Cab on-board signaling solution. It is compatible with both new and existing rolling stock.

A key technical adaptation for this project is a new-generation position measurement system. It relies on satellite positioning to ensure reliable operation in Norway’s harsh climatic conditions. This system is critical for reducing dependency on physical, ground-based signaling equipment, a central goal of the ERTMS strategy.

Market Impact Analysis

This milestone solidifies Alstom’s role as the primary technology partner for Norway’s ambitious signaling modernization. Successfully deploying a satellite-based positioning system in challenging Nordic weather serves as a powerful case study for Alstom, potentially influencing procurement decisions in other regions with similar climates. For Norway, the program’s progress is a critical step toward a fully interoperable, higher-capacity rail network with significantly lower long-term maintenance expenditures for infrastructure manager Bane NOR.
