Siemens Mobility Wins Stockholm Metro Electrification Contract

The Stockholm Extended Metro Administration has awarded Siemens Mobility the contract to deliver the rectifier and network substations for the expansion of the Stockholm Metro.

This contract is part of the extension works on the yellow metro line, which will run from Odenplan to Arenastaden, and an extension of the blue line to Barkarby in the northwest and to Mack and Söderord in the southeast. The blue line will also be linked with the green line at Hagsätra station and a new section will be built between Fridhemsplan and Älvsjö. The project has a total value of around 21 million euros. Construction will begin right away and continue over several years. Siemens Mobility will deliver on this contract gradually over the course of the construction period.

Michael Peter, CEO, Siemens Mobility, said:

“A well functioning metro system is an important factor in the everyday lives of the people in and around Stockholm. When the yellow line and other expansions are in place, more people will be able to use this efficient and sustainable mode of transport, and Siemens Mobility is pleased to be part of such a comprehensive and important project that will improve the service and comfort delivered to passengers.”
