Tramway City

The tram network in Stockholm is undergoing a major expansion. Tramway City is expected to carry 63,000 passengers per day in 2030 and will supply the new Royal Seaport district with efficient and environmentally friendly public transport.

A Major Expansion for Stockholm’s Tram Network

Tramway City will provide a climate-smart, high-capacity connection between the suburb of Lidingo, Stockholm Royal Seaport and Stockholm City centre. The tramway will also be extended to the Sergel Square / Central Station, reaching the central hub of Stockholm's public transport. Changing between commuter train, subway, bus and tram lines will be easy and efficient once the extension is completed.

The Tramway City project includes three elements: the modernization of Lidingo line, the construction of a new tram depot and the expansion of the existing line 7 in two directions. The entire Tramway City will cover 15.9 km and include 30 stops. A depot with space for 30 trams is being built in Lidingo.

The Tramway City project has a strong focus on sustainability and will be certified by CEEQUAL, which assesses the sustainability of infrastructure projects. Tramway City has already received its first CEEQUAL certification for work on tram stops accessibility.

Flexibility and Communication are Key

One of the major challenges was to find solutions to build the new tracks in the existing environment with on-going traffic and laying the new tracks without disturbing local retail activity. Another challenge has been communication with the public and with information services to brief local residents on construction plans.

A Dedicated Team in Action

WSP has provided preliminary design and detailed design for the line, including nine stops. Services include permanent way, road design, landscape architecture, geotechnics, rock engineering, land development, surveying and mapping, cable ducting, acoustics, traffic, water and sewerage, environmental impact assessment, risk and safety, 3D-model, cost estimates and project management.

We mobilized a multi-disciplinary team of experienced engineers, architects, urban planners, traffic and construction planners, cost managers and environmentalists, who established a clear strategy to reduce the scheme risk profile and develop and clarify the delivery program. Relying on high competence, extensive resources, committed staff and very good relations with the client, the project has been extremely fruitful.
