This is a project that is part of the broader planning of the Ministry of Infrastructure and Transport and concerns the modernization of rail transport.

In this section, there is a problem in the infrastructure of the lines in the length of 52 km (from Menidi to Oinoi) and as a result there are interruptions in the speed of the passing passenger and freight trains, and therefore overall delays. It must be noted that the line interruption is not required for the execution of the project. The contracting authority of the project is ERGOSE. The cost of the auction is estimated at around 95 million euros and is one of the largest new railway projects of this programming period.
