ATTIKO Metro published an invitation to tender on April 10 for contracts to build and equip the initial phase of Athens metro Line 4.

The 13km Section A will link Alsos Veikou with Goudi serving 14 new stations, including interchanges with existing lines at Panepistimio/Akademia and Evangelismos. Stations will be constructed at depths of between 20m and 34m below street level. Platforms will be up to 110m-long and all stations will be equipped with platform screen doors.

The project includes the construction of a 10km double-track tunnel, which will be built using TBMs, and an 840m-long single-track tunnel connecting the new line with lines 2 and 3.

The line will be equipped with CBTC and 750V dc electrification. Services will be operated by a new fleet of 18 trains.

The depot at Sepolia will be expanded and a new operational control centre will be built, which will incorporate the existing metro and light rail lines.

Initial ridership on Section A is forecast to be at least 220,000 passengers per day, increasing to 310 passengers per day when all phases of Line 4 are complete.
