• Inside Piraeus station, at the end of Line 1, so the train ride there is part of the outing
• Labels in Greek, with English leaflets on hand for visitors who don't read it
• Four levels of exhibits: the ground floor, a mezzanine, and a first and second floor

Run by retired staff of the Athens-Piraeus electric railway, this museum fills the old post office of Piraeus station, where Line 1 ends. The ground floor centers on an old wooden train carriage. Three more levels show objects from the stations, plus photographs and documents from the railway, the Piraeus-Perama light railway and the old harbor tramway.
