citat :
"Currently there are is no direct passenger service between Piraeus, Athens and Athens International Airport. Passengers to the Airport travel by a Kiato train to Ano Liosia and change there. Alternatively they travel by an ISAP train to Nerantziotissa and change to a Proastiakos train there."
