ERTMS
Norske Tog is engaged in the installation of onboard equipment for the European Rail Traffic Management System (ERTMS) on its train fleet, in close collaboration with Alstom. This project is aimed at rendering the trains compatible with the newly introduced digital signaling system, ERTMS, which is designed to serve as a standardised system across all European nations.
Project overview
The main goal of the project is is the comprehensive retrofitting of Norske Tog's train fleet, enabling them to seamlessly operate on the advanced data-based signaling system, ERTMS. This transformation is essential in preparation for the inauguration of the inaugural ERTMS-equipped line in Norway, scheduled for 2024.
Signal-related errors have been a challenge for the Norwegian railway system for a long time. ERTMS promises to offer a more robust and reliable railway infrastructure, resulting in improved punctuality. Furthermore, the heightened level of automation inherent in ERTMS will mitigate human errors, thus enhancing overall safety.
In practical terms, ERTMS operates by facilitating communication between the onboard system and the signaling system governing Norway's rail network. The driving authorization dispatched to the onboard ERTMS system furnishes the train operator with vital information, including the permissible speed and the extent of the driving permit.
In cases of excessive speed or the train surpassing its designated boundaries, the system will automatically engage the brakes. With this novel system in place, train operators will receive all pertinent information via a display screen within the driver's compartment, obviating the need to rely on traditional light signals along the railway.
Norske tog is assuming responsibility for the comprehensive installation of onboard equipment across its train fleet, committing a substantial investment of NOK 1.1 billion towards the integration of ERTMS. Meanwhile, Bane NOR is tasked with the modernisation of the signaling infrastructure.
Project status
For the convenience of travellers, ERTMS is being progressively phased in. First up is the northern section of the Gjøvik Line, where ERTMS is scheduled to go live in 2024. Subsequently, by 2030-2032, ERTMS will be rolled out at Oslo S, and by 2034, it is anticipated to be operational across all railway lines in Norway.
As of November 2024, the conversion of all ten type 75 trains on the Gjøvik Line has been completed and they are now in service. On the Vestfold Line, the remodelling of the type 74/75 trains is ongoing, and so far six trains have been fully rebuilt and put into service. Upgrades have also been carried out on the Nordland Line, where two type 93 trains and one type DI4 train have now been rebuilt.
The aim is for the ERTMS on-board system to be installed in all Norwegian trains by 2032.
