State-owned rolling stock company Norske Tog has summoned Alstom’s management to a meeting in Oslo on 2 March, following the discovery of bogie defects during lab tests. The issue has forced the suspension of trials in Norway for the new N05 series trains, formerly referred to as Class 77.
The contract, awarded in 2021 and signed in January 2022, covers up to 200 Coradia Stream units for the Nordic region. Alongside the framework agreement, an initial batch of 30 trainsets was ordered, with a further 25 added in February 2023. Each train comprises six cars and is scheduled to enter service in June.
A total of 36 sets will operate on Oslo’s suburban lines L1 and L2, while 16 will be deployed on regional routes. The French manufacturer has temporarily suspended testing as a precaution, after uncovering irregularities in a component supplied by a European subcontractor. Norske Tog, which is sending a technical team to Alstom’s facilities, warns that the issue could lead to additional contractual penalties if it causes further delays.
The project has already faced significant setbacks due to supply chain issues and production challenges. When the contract was signed, entry into service was expected during 2025. However, the first train arrived in Norway in June 2025 to begin its testing phase.
