About the project

In the development of a sustainable society, sustainable transport is an important piece of the puzzle. Part of the expansion of the West Coast Line is a double track and a tunnel under the center of Varberg. The Varberg-Hamra section is nine kilometers long, of which approximately 3 kilometers of the section will go in a tunnel under the center of Varberg.

The railway today requires a large space in the urban environment because it cuts through the city. Moving rail traffic underground significantly increases road safety as the tracks above ground have a number of railway crossings where the risk of accidents is high. The speed on the entire route increases - through Varberg's station area, the speed is increased from 90 km / h to 160 km / h. From Varberg station and south, the speed is increased from a maximum of 130 km / h to a maximum of 200 km / h.

The big gain is the increase in capacity from single track to double track. It also provides significantly greater opportunities to deal with train delays. Varberg is one of the Swedish municipalities that is growing fastest in relation to its population and the double track through Varberg will be an important part in giving more people the opportunity to commute faster to work and education. The new double track enables accessibility to increase when more trains can be accommodated. According to the plans, the trains will start rolling on the new track in 2024 and the project will be completed in 2025.
