On Wednesday April 11th, first trial trip has been done on the new Suburban Train line, connecting Airport, Athens and Piraeus.
This is actually an extension on the original line that has been operating since the Athens Olympics, just connecting Airport to Athens downtown.
Start of operation has been announced for end of May 2007.
Line will be operating every 30 mins, from early morning to late evening, covering the Airport -> Piraeus Seaport distance in just 50 minutes, under a single ticket. without any train change.
Up till now Airport - > Seaport trip had to be done either on Blue Metro Line, connecting to Green Metro Line on Monastiraki with a trip duration around 70 minutes, either on Express Bus.
New choice will be faster, with a speed around 80 kmh / 50 mph and without any train change.
Speed over 100 kmh / 65 mph will be achieved when full conversion of all on ground lines to subway lines will be finished, estimated at 2011.
Anyway, a 50 mins ride will be faster even from a cab, not to mention the cost :)
