Athens–Lavrion Railway

Locomotive Γ10 of Attica Railways
Line length	74 km (46 mi)
Track gauge	1,000 mm (3 ft 3 3⁄8 in)

Athens–Lavrion Railway was a 1,000 mm (3 ft 3 ³⁄₈ in) (metric gauge) railway line connecting downtown Athens with Eastern Attica and the mining town of Lavrion in Greece.

The contract between the Greek government and the Hellenic Company of Lavrion Metallurgies was signed in 1882. The line would be 76 km long, with a branch line from Heraklion to Kifissia. A new company, Attica Railways (Greek: Σιδηρόδρομοι Αττικής), was founded to take over the new line.

The line from Attiki station to Kifissia (a northern suburb) was opened on February 2, 1885 and was later extended further north to Strofyli. The main line to Lavrion was officially opened on June 20, 1885, although the section Keratea–Lavrion was in limited use before that date.

In 1889 the line was extended by 2 km towards the center of Athens, the station being located at Lavrion Square, near Omonoia Square. The section between Lavrion Square and Attica remained in use until 1926, when it was replaced by a tram line.

The section from Athens (Lavrion Square) to Heraklion was 9.2 km long, from Heraklion to Lavrion 56.85 km and from Heraklion to Strofyli 7.4 km. All sections were single track, with passing loops at most stations.

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

A short (273 m), single track spur branched off at a junction located 1 km after Heraklion station, followed a 90 degrees right curve and ended at Kalogreza or Nea Alexandreia station. The branch line was constructed in or just after 1944 and served the local brown coal (lignite) mines of Kalogreza. It was closed in 1957, sharing the fate of Athens–Lavrion railway. There are no visible traces of the tracks left. Another branch line served Cambas Winery at Leontarion (Kantza). In the Lavrion mining area the line connected with the industrial networks of the two mining companies.
