Ioannina to the west and the town of Perama to the north are urban settlements fringing the lake while the remaining of its periphery is composed of farmland.
In addition to slight extensions to Lines 1, 3 and 4, the proposed expansion will create Lines 5 (Ano Liosia – Vyronas), 6 (Melissia – Perama/Piraeus), 7 (Chaidari – Alimos, crossing the Attiki through downtown Athens) and 8 as a partial circle around Athens (Katechaki – Sepolia – Kallithea – Dafni – Pangrati).
A suburban standard gauge light railway line (Piraeus-Perama light railway) opened in 1936, connecting downtown Piraeus with Perama and terminating inside the Naval Base at Amphiali.
