The project involves the construction of the New Double-Track High-Speed Railway Tithorea – Lianokladi – Domokos. The new double-track line, which is 106 km long, is going to replace the mountainous section of the existing 122 km long single-track line.

The new alignment was designed for speeds of 160-200 km/h. The line starts at Tithorea Railway Station, it runs eastbound crossing Kallidromo mountain through a twin-tube single-track tunnel, each tube 9.036 m long, and then it runs through Sperchios river plain, before finally reaching the RS of Lianokladi. The line then crosses Othrys mountain through a twin-tube single-track tunnel, each tube 6.380 mlong, it runs through the dried-up lake of Xyniada and continues up the mountain of Domokos, where it reaches Domokos RS.

3 infrastructure contracts are currently in progress with a total cost of 617 million Euros.

To complete and open to traffic the new line, the following has been planned:

Installation of GSM-R wireless communication networkon the entire new double-track high-speed railway line Tithorea - Domokos.

Project objectives:

- reduce travel time between Athens and Thessaloniki to 3.5 hours, after completion of works.
- restore discontinuities of the trans-European transport networks, part of which is PATHE/P rail corridor that also includes this project.
