Introduction
In November 2022, the Finnish Transport Infrastructure Agency (Väylä) initiated a project to electrify the railway line between Seinäjoki and Oulu, with an estimated cost of €165 million. This project aims to improve railway transport efficiency and reduce emissions.
Project Scope and Timeline
The electrification project encompasses the 288-kilometer-long railway section between Seinäjoki and Oulu. The plan includes the construction of new substations in Kokkola and Ii, as well as the upgrading of existing substations in Seinäjoki, Tervola, and Oulu. Construction is scheduled to commence in 2023, with completion expected by the end of 2026. The project also involves the installation of approximately 600 kilometers of new overhead contact lines.
Budget and Funding
The total estimated cost for the Seinäjoki-Oulu railway electrification project is €165 million. The funding will be provided by the Finnish state. The project is expected to create numerous jobs during the construction phase.
Operational and Environmental Benefits
The electrification of the Seinäjoki-Oulu railway line is anticipated to significantly improve the efficiency of rail transport. It will facilitate the use of electric trains, which are more energy-efficient than diesel locomotives. The project is expected to reduce carbon emissions from railway operations, contributing to Finland’s climate goals. The implementation will also increase the capacity of the railway line, enabling the transportation of more goods and passengers.
