Athens International Airport
The construction of a new rail line between central Athens, its eastern suburbs and the new Athens International Airport was decided in 1992–1993. During the construction of Attiki Odos motorway in the late 1990s, space was left between the main carriageways for the railway line and after two years of construction, the line to Athens International Airport opened in 2004. The first suburban services between Athens and the Airport were inaugurated using Stadler GTW and Siemens Desiro DMU trains.
