The One-hour Turku Rail Link is a new high-speed, double-track rail link between Helsinki and Turku that will significantly reduce the travel time between the cities and create opportunities for growth and development.

The project will be implemented in four parts: the Espoo regional railway line, a new direct railway line from Espoo to Salo via Lohja, the Salo–Turku double-track railway line, and the Turku rail yard area.

Totally new direct railway line between Espoo and Salo and a double-track line between Salo and Turku will significally shorten the length of railway line and so also the travelling time.

The construction project for the Espoo regional railway line has already reached the construction phase as work is to begin latest in early 2022.
