Siemens Mobility to Electrify Stockholm Metro extension

Siemens Mobility has been selected by Region Stockholm Extended Metro Administration to supply the rail electrification system for the new Stockholm Metro extension. Siemens Mobility will deliver rectifier stations and network stations.

The project is an expansion of the metro with a brand-new Yellow line that will run from Odenplan to Arenastaden. The metro’s Blue line will be extended from Akalla to Barkarby in the north west and from Kungsträdgården to Nacka in the south east. In addition, the Blue Line will be connected to the green Hagsätra branch, and a new section will be built between Fridhemsplan and Älvsjö.

“A well-functioning metro system is an important factor in everyday life for the residents of the Stockholm region. When the yellow line and other extensions are in place, even 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, which will enhance passenger service and experience,” said Michael Peter, CEO Siemens Mobility.
