This project consists of replacement of the overhead contact line system and auxiliary power line including transformers. The overhead contact line system shall also be converted to AT system. This applies to a double track. The route concerned is about 40 km long, the total distance is therefore 80 km.
The objective of the project is to revive the standard of the overhead contact line system and convert to AT system. The performance contract consists of replacement of the overhead contact line system and auxiliary power line including transformers. The overhead contact line system shall also be converted to AT system. The contract work is scheduled to be carried out in 2021-2024. All the parts of the projects are to be finalised and opened for traffic (ÖFT) in December 2024.
The entrepreneurial works will be carried out in a performance contract. The cost of the performance contract is estimated to 350-450 MSEK.

Project background facts
The Västra Stambanan line between Gothenburg and Alingsås is one of the country's most stressed courses and a large volume of long-distance trains, commuter trains, regional trains and freight trains operates it daily.
The entire route between Gothenburg and Stockholm was opened for traffic in 1862 and electrified in 1926, then first as a single track. In 1958, a double track was built which was simultaneously electrified.
Some of the overhead contact line posts on the route are the original ones that remain and these are in generally poor condition. Because the overhead contact line is old and worn, the risk of disturbance is substantial.
Today’s overhead contact line was established in 1980.
Today’s auxiliary power line including transformers was established in 2003.
The railway runs through Natura 2000 and water source areas. There are 4 tunnels on the route and the railway runs through several rock cuttings.
