[7][8] Following the Finnish government's request for investment in February 2020,[9] the EU's Connecting Europe Facility approved €37.5 million in funding for the Helsinki–Turku high-speed rail project in July 2020,[10] to form an integral part of the Trans-European Transport Network's Helsinki–Valletta Corridor.

[12] In July 2024, the European Commission declined an application for funding the construction of the railway, prompting multiple members of parliament to question the future of the project.

[14] The line is planned to branch from the Rantarata after Espoo railway station, connecting to Salo following the Finnish national road 1 corridor, through the municipalities of Vihti and Lohja.

[16] In July 2019, residents of the Lukkarinmäki area of Salo have gathered a petition of 2,500 signatures against building the line through their neighbourhood, due to the potential need to demolish some properties.

By reducing the journey time to 75 minutes between Helsinki and Turku, along with new stations in Vihti and Lohja, a further 1.6 million passengers are expected annually.
