On 18 July 2006, three new stations were added: Ano Liosia, Aspropyrgos, and Magoula. On 4 June 2007, the line was extended from Athens Central Station to the port of Piraeus with 3 intermediate stations at Lefka, Rentis, and Rouf. This extension linked the airport with the port of Piraeus. On 9 July 2007, Proastiakos services reached the new station at Kiato. TrainOSE also runs "Proastiakos" commuter rail services between the cities of Thessaloniki and Larissa, on the modernised and electrified main line. The service initially operated from Thessaloniki to Litochoro in 2007 and was extended to Larissa in 2008. In 2009 the brand name "Proastiakos" was also used for a short-lived regional service of four trains in each direction per day, connecting the cities of Xanthi, Komotini, and Alexandroupolis in the region of Western Thrace. In 2010, TrainOSE created the Proastiakos Patras service which runs on the old Athens-Patras line from Agios Andras to Agios Vassileos.
