The primary objective of the project is to create a link between Stockholm's existing heavy rail network from the main line through the city centre to the new 6km City Line, which is due to open in 2017, with Strukton also responsible for construction including a new tunnel between Stockholm South and Tomteboda.
Works will comprise remodeling of the track layout and installing new signalling. The project is scheduled to start in September and will be completed in August 2016.
