Swedish Transport Administration
The Swedish Transport Administration (Trafikverket) has started detailed planning and is in the process of deciding the best route between Gothenburg–Borås and Linköping–Södertälje (Ostlänken), however no specific dates have been determined for the start of construction on these lines. An informal proposal by Trafikverket is an operational track by 2025. There is political and (primarily) regional pressure to build these railways as soon as possible. Cost estimates are about 10 bn SEK for Gothenburg-Borås and 24 bn SEK for Linköping-Södertälje.
