The Copenhagen Light Rail (Hovedstadens Letbane) opened its southern section on October 26, 2025, enhancing public transit options for residents, patients, and employees across the greater capital region. The full 28-kilometer line is set to be completed by summer 2026, with estimated annual ridership reaching 14 million by 2031.
New Public Transit Service Enhances Regional Connectivity
On Sunday, October 26, 2025, the long-awaited Copenhagen Light Rail officially began operating its southern route between Ishøj and Rødovre Nord. This marks a major advancement in public transportation for Denmark’s Capital Region. It will significantly improve cross-regional connectivity across 11 municipalities. The initial phase offers a direct and sustainable alternative to road traffic, connecting key residential and commercial areas. The light rail will help people travel more easily across the region.
The opening was celebrated with public events at several light rail stations, including Glostrup Hospital, where families were invited to festivities featuring coffee, children’s activities, and opportunities to explore emergency response vehicles. Free rides were offered throughout the day on both the light rail and Bus 300S. Many people joined the events and tried the new light rail.
A Sustainable and Accessible Alternative to Driving
Once completed in the summer of 2026, the Copenhagen Light Rail will stretch across 28 kilometers from Ishøj in the south to Lundtofte and to the Technical University of Denmark (DTU) in the north. The line will feature frequent service. It will be running every 10 minutes during peak hours. The frequency is planned to increase to every 5 minutes once the full line is operational.
This expansion is designed not only to reduce road congestion but also to support Denmark’s climate goals by shifting daily commuters from cars to public transit. The system has been developed with accessibility in mind. One of the goals is to ensure that passengers in wheelchairs, with strollers and bicycles can comfortably use the service.
With the ability to transport tens of thousands of people daily, the light rail will offer direct links to major institutions, including Rigshospitalet Glostrup and Herlev Hospital. This is expected to significantly ease commutes for hospital staff and improve access for patients.

Ishøj, Vallensbæk, Hvidovre, Albertslund, Brøndby, Rødovre, Høje-Taastrup, Herlev, Gladsaxe, Glostrup, and Lyngby-Taarbæk. By pooling resources and coordinating urban development plans, these communities have successfully delivered one of Denmark’s most ambitious infrastructure upgrades.
This collaboration is seen as a model for future projects. It demonstrates that large-scale regional transit solutions are possible through unified planning and shared investment. The project has also received support from the Danish state, further underlining its national importance.
Looking Ahead to Full Completion
Once the northern segment opens next year, the light rail will connect more densely populated and high-traffic areas. This includes business parks in Hersted, Gladsaxe, and Lautrup. It will also offer seamless transit to DTU and other educational institutions. Supporting students and researchers with enhanced mobility.
