The causes
The data does not say why.
Method and limits
- Source: SNCF open data, monthly TGV regularity by route (AQST) and national monthly TGV regularity, ODbL licence.
- Period: Decembers 2022 to 2025 for routes, 2015 to 2025 for national figures.
- Measure: "on time" is defined at the top of the page. The rate covers trains that ran. Cancelled trains are counted apart.
- Limits: whole months only. The data cannot isolate the Christmas holidays. Only routes with at least 150 planned trains across the 4 Decembers are kept. The series mixes INOUI and OUIGO. The lateness limit changes with trip length, so routes are not strictly comparable. Routes overlap: no national sum.
