[1] The line from Attiki[a] to Kifissia (a northern suburb) was opened on 2 February 1885 and was later extended further north to Strofyli.

The main rolling stock depot and repair workshop were located at Attiki station, with additional facilities at Lavrion.

[2] The branch line was constructed in or just after 1944 [citation needed] and served the local brown coal (lignite) mines of Kalogreza.

Between 1900 and 1925 ten 2-6-0T locomotives were procured in four batches: one from Vassiliadis Works in Piraeus, and the remaining nine from Krauss in Germany.

The line was closed to passenger traffic in 1957, due to political lobbying by private bus owners.

In 1962 the connection between Kato Liosia and Heraklion was severed due to the construction of the new Athens–Thessaloniki highway and the line was abandoned.

Museum railways of Attica Co. (Greek: Εταιρεία Μουσειακών Σιδηροδρόμων Αττικής or Greek: ΕΜΣΑ), a preservation society in the form of a non-for-profit company, maintains two small sections each 3 kilometres (1.9 mi) long, one near Kalyvia and one near Keratea.
