Norway: Hitachi Rail and Bane NOR Commission Digital Interlocking on Dovre Line

Hitachi Rail and Bane NOR have commissioned a new L90-5 electronic interlocking system at the Hove stabling facility on the Dovre Line near Lillehammer, Norway. This project has introduced digital control of signalling and track components in the area.

The electronic interlocking replaces conventional control methods with a digital platform that manages points, signals and level crossings. The system is designed to support more consistent train movements and streamline infrastructure management.

The installation at Hove covers one interlocking module and a local operator workstation. It connects to 42 point machines, three level crossings, 15 main signals, 28 dwarf signals and 59 detection points. These elements are now supervised and controlled through the new electronic interface.

Project delivery involved engineering and technical teams from Norway, Germany and Romania. The commissioning was completed within the planned schedule and in line with national rail network requirements.

The L90-5 system installed at Hove includes:

• One interlocking module
• One local operator place
• 42 point machines
• Three level crossings
• 15 main signals and 28 dwarf signals
• 59 detection points

Astrid van de Weijer, Project Manager Hove and General Program Manager SignAn, Hitachi Rail said:

This achievement demonstrates how technological expertise and international collaboration can transform rail operations. This project reinforces our commitment to innovation and sustainable mobility. By modernising Norway’s infrastructure and enabling smarter operations, we help create better journeys for passengers and contribute to reducing environmental impact.

Bane NOR is progressing a broader programme of signalling and control upgrades as part of its network development plans. The Hove installation forms part of this effort, with a focus on operational reliability, maintainability and capacity for passenger services.
