The Helsinki–Turku high-speed railway or Espoo–Salo-oikorata (Espoo–Salo direct line), also formerly known as the ELSA-rata (Espoo-Lohja-Salo), is a proposed railway line in the planning stage to provide a more direct connection between Helsinki and Turku, Finland than the current Rantarata railway line which follows the southern coast. The project is also known as Turun tunnin juna (Turku one hour train), despite the fact that a journey between Helsinki and Turku on the new line would last about 1 hour and 18 minutes.

The current Orpo cabinet plans to fund construction between Espoo and Lohja and between Salo and Kupittaa. As of December 2025, all municipalities on the route have approved funding for the project, except Kirkkonummi, which voted to not provide any funding the project.
