Description
As of December 2010, the system served 33 stations, not counting the four OSE stations on the Airport line. Both Metro lines have passenger connections with ISAP (Line 1), Proastiakos, the Athens Suburban Railway and the Athens Tram system. There is a physical connection with ISAP railway at Attiki station.
The system consists of standard gauge lines in intermediate depth tunnels, with both up and down lines in a common tunnel. The system is electrified with the third-rail system, using a nominal voltage of 750 V DC.
The length of the blue line (line 3) as of April 2008 was 16.4 km not including the suburban railway part to the airport, or, as of February 2008, 37.6 km including the 21.2 km of the line that it shares with the suburban railway system of Athens. The length of the red line (line 2) as of July 2008 was 10.9 km. This brings the overall length of the green, red and blue lines to approximately 74 km.
An automatic train supervision system (ATS) and a passenger information system (PIS) made by Alstom cover the whole network. Traditional color light signalling is limited to points and junctions.
The Athens Metro is heavily used, with approximately 700,000 passengers daily.

Famous quotes containing the word description:
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
