Athens Metro Line 1 is the oldest of the three lines currently in operation. The line was first opened in 1869 as the Athens & Piraeus Railway Co with steam hauled trains. The line at the time extended from Piraeus to Thision in Athens (one stop from Monastiraki). The underground station of Omonia (one stop from Monastiraki) was opened in 1930 and electrification of the line was completed in 1950. Today the line extends from Kifissia (opened in 1957) to Piraeus covering a distance of 25.6 kms with 24 stations.
The distances between the stations range from ½ km to over 2 kms.
