ABSTRACT
The existing Roslagsbanan, a commuter railway in the northeast of the Stockholm region, Sweden, will be extended with a new route in an approximately 3,5-kilometer-long tunnel through the city center of Stockholm to the hub T-Centralen. This new route is planned with tunnels and two stations located mostly in rock. The extension includes two new underground stations located at Odenplan and at T-Centralen, next to the existing stations and lines of the metro and railway systems. This complex project for the tunnels, stations and the correspondent civil works has great significance for Stockholm’s infrastructure and Stockholmers. This urban development has many technical challenges, among others the multiple crossings with existing tunnels and underground constructions in the city center. With several restrictions and prerequisites, everything needs to be planned in detail from an early stage, ensuring a buildable and sustainable solution, for effective construction times and cost control.
