Construction on Athens Metro Line 4 is making steady progress, with one of the two tunnel boring machines (TBMs) nearing the end of its journey. The TBM named 'Athena' has traveled from the Katehaki shaft to the Evangelismos shaft, passing several stations along the way including Gouda, Zografou, Ilisia, University Campus, and Kaisariani. However, despite this progress, the delivery timeline for the new metro line, which is expected to serve heavily populated areas of the capital, remains unclear due to delays encountered in preliminary works for the stations.

The second TBM, 'Victory', began its journey from the Veikou shaft and has successfully advanced through several stations including Alsos Veikou, Galatsi, and Elikona, currently reaching Kipseli. It is estimated that this TBM will complete its mission by the end of 2026. The project is crucial for enhancing public transportation in Athens, allowing easier access for residents in densely populated neighborhoods, and reducing traffic congestion in the city.

The uncertainty surrounding the delivery schedule of Line 4 is a concerning aspect for both government officials and residents awaiting improvements in their transit system. As completion dates are continually pushed back, the anticipation grows for the benefits the new line will bring once it finally begins operations, potentially transforming how public transport is utilized in Athens.
