Siemens Mobility and infrastructure contractor Aarsleff Rail have completed the full delivery of the Greater Copenhagen Light Rail, opening a 28-kilometre cross-regional transport link between Ishøj in the south and Lundtofte, north of Lyngby. The light rail runs along Ring 3 and serves 29 stations across eight municipalities. The new connection links residential areas with workplaces, hospitals, educational institutions and major public transport hubs, creating a new transport backbone for the Greater Copenhagen region.
The line is expected to carry around 12,000 passengers a day and reach annual ridership of approximately 14 million by 2030. It is designed to provide a reliable alternative to private cars and support more sustainable mobility across the metropolitan area. Siemens Mobility delivered the project as a turnkey solution. Its scope included 29 Avenio light rail vehicles, electrification, signalling and communication systems, depot and workshop equipment, system integration and project management. The company will also provide maintenance services for 15 years.
“With the full opening of the Greater Copenhagen Light Rail, we are proud to see Siemens Mobility’s turnkey expertise driving this important public transport project in Denmark,” said Léon Soulier, CEO, Turnkey Business Unit at Siemens Mobility. “From the delivery of the Avenio vehicles to electrification, signalling, communications, system integration and long-term maintenance, the project provides a major improvement to daily mobility while supporting sustainable transportation.”
The first section of the light rail opened in October 2025 with 12 stations. The latest phase adds the remaining 17 stations, completing the route and strengthening connections with six S-train interchanges. During the initial operating period, services will run every five to eight minutes during peak daytime hours. Evening and Sunday services are planned at 10-minute intervals. The frequent service is intended to make public transport a convenient option for commuters and other passengers travelling across the region.
The fleet consists of 29 Siemens Avenio vehicles, each measuring 36.9 metres in length and capable of carrying up to 260 passengers, including 64 seated passengers. The vehicles feature step-free boarding and dedicated areas for wheelchairs, bicycles and prams. The light rail vehicles can operate at speeds of up to 70 km/h and are designed to provide a comfortable and accessible passenger experience.
The project was delivered through collaboration between Siemens Mobility, Aarsleff Rail and Greater Copenhagen Light Rail. It represents a major addition to Denmark’s public transport network and is expected to support greener and more connected travel across the Copenhagen metropolitan area.
Siemens Mobility is a separately managed company of Siemens AG, providing rolling stock, rail automation, electrification, software, turnkey systems and related services. In fiscal 2025, Siemens Mobility reported revenue of €12.4 billion and employed around 43,400 people worldwide.
