• Lynetteholm N Station

Additionally, the Copenhagen Central Station facility will be engineered with provisions for potential future extensions toward Østerport via Gammel Kongevej, ensuring the metro network maintains flexibility for future expansion as the city continues to evolve.

Connectivity and Integration With Existing Systems

One of the M5 line’s most significant advantages lies in its strategic integration with Copenhagen’s existing metro infrastructure. The line’s routing has been carefully planned to create efficient transfer opportunities at multiple key locations, ensuring passengers can seamlessly connect between different transportation modes and metro lines.

At Copenhagen Central Station, travelers will enjoy comprehensive transfer options to the established M3 and M4 metro lines, connecting them to virtually every neighborhood in the metropolitan area. The same station provides connections to regional and long-distance rail services, as well as the S-train commuter network. This multi-modal integration transforms Central Station into an even more powerful transportation hub, consolidating access to various transit options in a single, convenient location.

The DR Byen station creates an important interchange between the M5 and the M1 line, while Lergravsparken provides connection points with the M2 line. These strategic transfer locations ensure that passengers throughout Copenhagen’s broader metro network can access the new line’s routes, distributing ridership efficiently across the system.

Urban Development and Economic Catalysts

The M5 metro line serves as a crucial enabler for Copenhagen’s ambitious urban development agenda. The project is specifically designed to unlock growth in areas that currently lack metro service while facilitating planned development in the East Harbour and Lynetteholm districts.

The Lynetteholm project represents one of Copenhagen’s most innovative urban development initiatives. This artificial island will incorporate new residential communities, office spaces, recreational facilities, and public spaces. The M5 line’s extension to this area will ensure residents and workers can access the broader city without reliance on automobile transportation, supporting Copenhagen’s environmental objectives while promoting the project’s economic viability.

Beyond specific development projects, the M5 line strengthens Copenhagen’s broader economic competitiveness. Enhanced transit connectivity improves the city’s attractiveness to businesses, professionals, and residents, while reducing transportation costs and congestion. The improved accessibility to eastern neighborhoods opens previously underdeveloped areas for investment and revitalization.

Addressing Network Capacity Challenges

Copenhagen’s existing metro network, particularly the M1 and M2 lines and the cross-harbor sections, has begun experiencing capacity constraints during peak travel periods. Population growth and increased urbanization have generated transit demand that approaches the limits of current infrastructure. The M5 line addresses this critical challenge by providing an alternative route for passengers, distributing demand more effectively across the network.

By offering a new major corridor from Central Station through Amager, the M5 reduces pressure on the M1 and M2 lines while simultaneously improving overall system resilience. The distributed network design ensures that maintenance or operational disruptions on any single line create fewer cascading impacts throughout the system.
