How is French train punctuality measured by SNCF?

SNCF measures punctuality as the percentage of trains arriving on time. For TER regional trains and Transilien or RER lines, regularity is calculated at a five-minute threshold, while TGV high-speed train indicators include composite regularity and punctuality at origin.

Which rail services are included in this France train punctuality table?

The table includes monthly punctuality data for TGV high-speed trains, including OUIGO and international services, TER regional trains by administrative region, and Transilien and RER lines in the Paris region.

How far back does the France train punctuality data go?

The monthly train punctuality and regularity series for France start in 2013 and are updated continuously as new open data is released by SNCF Voyageurs.

What is the difference between TGV regularity and punctuality at origin?

Punctuality at origin measures the share of TGV trains departing on time, whereas composite regularity measures the share of TGV trains arriving at their destination within a specific margin depending on journey length.

About this data

French train punctuality and regularity rates by region and line, published monthly by SNCF. This dataset tracks the monthly share of on-time services for TGV high-speed trains, TER regional trains, and Transilien or RER lines in Île-de-France. Regularity is measured at five minutes for TER and Transilien, while TGV indicators include composite regularity and punctuality at origin. The series cover regional axes and specific RER lines since 2013.

Frequently asked questions

How is French train punctuality measured by SNCF?: SNCF measures punctuality as the percentage of trains arriving on time. For TER regional trains and Transilien or RER lines, regularity is calculated at a five-minute threshold, while TGV high-speed train indicators include composite regularity and punctuality at origin.
Which rail services are included in this France train punctuality table?: The table includes monthly punctuality data for TGV high-speed trains, including OUIGO and international services, TER regional trains by administrative region, and Transilien and RER lines in the Paris region.
How far back does the France train punctuality data go?: The monthly train punctuality and regularity series for France start in 2013 and are updated continuously as new open data is released by SNCF Voyageurs.
What is the difference between TGV regularity and punctuality at origin?: Punctuality at origin measures the share of TGV trains departing on time, whereas composite regularity measures the share of TGV trains arriving at their destination within a specific margin depending on journey length.
