SYSTRA has been awarded its first major contract in Stockholm, Sweden, supporting the development of the city’s first automatic metro line.

The new Yellow Line will become the sixth line in Stockholm’s metro network. The fully underground route will link Älvsjö in the south to Fridhemsplan in the centre-west, with six new stations.

The project is expected to provide improved access to nearly 50,000 residents and accommodate up to 75,000 passengers per day by 2050.

SYSTRA will assist Förvaltning för Utbyggd Tunnelbana (FUT), the authority overseeing the metro expansion, in implementing all systems for the new line over a nine-year period.

This metro will be completely new, including its rolling stock. SYSTRA's three-year strategy in Sweden is validated by this contract, which is a great opportunity to showcase our expertise, particularly in automated metro systems. We look forward to supporting our Swedish customers in this promising programme.

The Yellow Line will be Sweden’s first driverless metro, utilising Grade of Automation 4 (GoA4) technology, the highest level of automation.

Platform screen doors will enhance passenger safety, while shorter, more frequent trains (75 metres in length compared to the existing 145-metre trains) will reduce waiting times.

This project marks SYSTRA’s first comprehensive systems project management contract in Stockholm, strengthening the company’s presence in Sweden and Scandinavia.

The core project team will be led by Oriana Castellanos, Pierre Castanier, and Neil Bullass, supported by technical experts from Denmark, Paris, and the United States.

Specifically, SYSTRA’s responsibilities include preparing technical tender documents and managing key aspects such as systems integration, interface management, operational system design, risk analysis, and mitigation strategies.
