The project is funded by the European Union (EU) and the Greek government and will serve an estimated 135,000 passengers per day when the work is completed in 2017, reducing journey times by an hour. The extension will enable passengers to travel directly to Piraeus from the Eleftherios Venizelos International Airport.
Alstom has a €32m share of the contract and will be responsible for design and installation of traction systems, including third rail, medium voltage supply and the distribution of low voltage power.
