Daily regularity SNCF lines

SNCF publishes on the website [my trains of yesterday](https://www.sncf.com/fr/engagements/transparence/info-regularite) a daily report of regularity and notable incidents of the previous day. This dataset is an archive of the information presented on this site. Every day SNCF operates 15,000 trains that carry 4,000,000 customers in France: — Transilien — 5,400 trains, 2.7 million passengers — Ter — 7,500 trains, 1 million passengers — TGV — 750 trains, 300,000 passengers — Intercités — 220 trains, 100,000 passengers ## Coverage This dataset covers SNCF’s passenger activity on the following services: — Transilian: information on the line. Where the route is operated jointly with another carrier (e.g. RATP on RER A and B), regularity is indicated only for the part operated by SNCF —B: information to the region — TGV: information at the axis (Eastern, Atlantic, etc.) — Intercity: information on the line (Paris-Rouen-Le Havre for example) In addition to the finest mesh, each activity has a punctuality _global_, for all TGVs for example. This is represented by the keyword ‘global’ for each day and mode of transport in the data. ## Calculation of regularity **This information is given by SNCF.** For Transilien services, the calculation is made on the percentage of passengers arriving with a delay of less than five minutes at their destination station. This criterion has been implemented since 2002 with IDF Mobilités (ex-STIF, the Syndicat des Transports d’Ile-de-France). The flow of passengers rising and descending on each train and station is regularly updated. This information is crossed with actual train traffic [1]. The results of RER A and B correspond to the production results for the part operated by the SNCF carrier. On TER the regularity shall be calculated on arrival of the train concerned [2]. A train is considered per hour if its delay is less than 5 minutes [3]. The indicator represents the percentage of trains per hour on trains that have traveled [4]. This indicator is used in monitoring quality of service with Organising Authorities. On Intercités, regularity is calculated at the arrival of the train at the end of the journey. A train is considered per hour if its delay is less than or equal to 5 minutes [3] for day trains and night trains (Paris — Toulouse — Latour de Carol/Cerbere/Rodez and Paris — Briançon) [3]. The indicator represents the percentage of trains per hour on trains that have traveled [4]. This indicator is used in monitoring quality of service with the Organising Authority. For TGVs regularity takes account of the different journey times of customers: — a train is considered per hour if its delay at the terminal is less than 5 minutes [3] for a journey less than 1h30 — a train is considered per hour if its delay at the terminal is less than 10 minutes [3] for a journey between 1h30 and 3h — a train is considered per hour if its terminal delay is less than 15 minutes [3] for a journey beyond 3h The four geographical areas of TGV correspond to the four Parisian TGV stations [5]. TGV Europe includes international trains from SNCF (Alleo, LYRIA, ELIPSOS, SVI). Trains operated by other railway companies such as Thalys and Eurostar are not taken into account. _Notes_ [1] Transilian service is fully clocked and trains have repetitive missions that allow a customer to borrow any equivalent train that arrives at the scheduled time for the intended destination even if it is not the theoretically planned train. The indicator reflects this trivialised use of trains. [2] Interregional trains are operated successively for two organising authorities. In this case each section is calculated to reflect the service rendered in each region. For the first section the calculation is made on the last station served in this region. [3] Arrival times are usually determined by sensors detecting the train’s passage at a specific point marking entry into the station and exceptionally by manual tracking. The accuracy of the measurements is the minute rounded to the bottom minute, which is in accordance with all the standards adopted for the preparation of timetables and timetables of service. [4] Measurement of deleted trains requires additional checks that are not available the next day as a train may have been renumbered, diverted to another route, equivalent station or partially limited. [5] Inter-sector TGVs, North<>Atlantic are included in the northern sector, TGVs between sectors East <>North and East Atlantic in Sector East, TGV intersector Atlantic<>South East in Sector South East and TGV Rhine Rhône from province to province in Sector South East. [6] Reprocessing may be carried out within days of publication to correct occasional anomalies. They normally affect the results only marginally in tenths of a point and the data are not updated in this form. [7] SNCF Robustesse is the continuous progress process implemented by SNCF to improve its regularity. ## Source code Find the source code to get this data [on GitHub](https://github.com/AntoineAugusti/mestrainsdhier-sncf).
