Grand Paris Express Line 15 South Opens
The first stretch of Europe's largest transport project: a 33 km automated orbital metro ring around Paris. Estimated date.
- Grand Paris Express is Europe's largest public transport project: four new automated metro lines (15 to 18) plus extensions, about 200 km of track and 68 stations, projected 2 million passengers a day[1]
- Line 15 South (Pont de Sevres to Noisy-Champs) has slipped repeatedly: from 2020 to end 2025, then summer 2026 (announced November 2024), and now fall 2027 per the June 2026 timetable, so the pin's October 2026 date is out of date[1][2][3]
- Newer timetable (June 27, 2026): Line 18 first section Massy-Palaiseau to Christ de Saclay from November 30, 2026 (floated for October 1); Lines 16 and 17 in 2027 to 2028; Line 15 East and West in 2031[2]
- Cost estimates rose from about EUR 20 billion (2009) to EUR 38.5 billion (Cour des comptes, 2018), around EUR 42 billion per a 2020 Senate report[1]
- Trains are driverless with headways as short as 85 seconds; Line 15 South is operated by ORA (RATP Dev, Alstom, ComfortDelGro)[1][3]
