The modernisation involves the replacement of 70 meters of track each night, for a total length of 25 km.
Upgrade works will also concern the replacement of sleepers and switches as well as ballast reconditioning. High-performance materials will be used to improve efficiency and enhance safety of the metro line.
To reduce inconvenience, works are carried out overnight. For this reason, on some days of the week, an early closure of the entire Metro line A, from Anagnina to Battistini, will be necessary according to the following timetable:
During the Metro closure times a replacement bus service will operate with up to 76 available buses and 152 expected runs.
