29 Stations, 29 Trams: Copenhagen Light Rail Fully Opens

The Greater Copenhagen Light Rail is now fully open, completing a 28-kilometre route between Ishøj and Lundtofte. Siemens Mobility supplied the 29 Avenio trams and most of the railway systems under a turnkey contract that also includes 15 years of maintenance.

The Greater Copenhagen Light Rail has entered full passenger service after the opening of the remaining section of the 28-kilometre route. The line runs from Ishøj in the south to Lundtofte, north of Lyngby, with 29 stations along Copenhagen’s Ring 3 corridor. It connects eight municipalities and provides interchange with the S-train network at six locations. Siemens Mobility delivered the project in consortium with Danish infrastructure contractor Aarsleff Rail.

Greater Copenhagen Light Rail Now Serves All 29 Stations

According to Siemens Mobility, the first section of the line opened in October 2025 with 12 stations. With the remaining 17 stops now in service, passengers can travel along the entire route. The new connection links residential areas with workplaces, hospitals, educational institutions and major public transport hubs across the Copenhagen metropolitan area.

According to the project figures, around 12,000 passengers are expected to use the light rail each day, while annual ridership is forecast to reach 14 million by 2030. During an initial transition period of three to six months, trams will run every five to eight minutes during peak daytime hours. Evening and Sunday services will operate every ten minutes.

The line will now provide an alternative to car journeys across one of Denmark’s busiest metropolitan corridors, particularly for trips that previously required travelling into central Copenhagen before changing direction.

Siemens Supplied Trams, Signalling and Electrification

Siemens Mobility supplied 29 Avenio light rail vehicles, along with electrification, signalling and communication systems. Its work also included depot workshop equipment, project management and overall system integration.

Siemens will be involved even after the opening through a 15-year maintenance agreement. "With the full opening of the Greater Copenhagen Light Rail, we are proud to see Siemens Mobility’s turnkey expertise driving this revolutionary public transport project in Denmark," said Léon Soulier, CEO of the Turnkey Business Unit at Siemens Mobility.

"From delivering 29 innovative Avenio light rail vehicles to electrification, signaling, communications, system integration, depot equipment, and long-term maintenance, this light rail system offers a strategic improvement to daily mobility while making a clear commitment to sustainable transportation," he added.

29 Siemens Avenio Trams Form the New Fleet

The fleet consists of 29 Siemens Avenio trams designed for the new route. Each vehicle is 36.9 metres long and can carry up to 260 passengers, including 64 seated passengers. The interior includes standing areas as well as dedicated space for bicycles, prams and wheelchairs. Step-free boarding is intended to make the vehicles easier to use for passengers with reduced mobility.

The trams have a maximum operating speed of 70 km/h. With six S-train interchanges along the route, passengers can transfer between the two networks without travelling into the city centre first.

Light Rail Connects Eight Municipalities Around Copenhagen

Unlike many urban tram projects centred on a city core, the Greater Copenhagen Light Rail runs across the metropolitan area along Ring 3. Its 29 stations connect eight municipalities and several important employment and education areas, so the route will improve journeys between suburbs and provide connections into Copenhagen’s wider rail network.
