Quai à Quai — Follow your journey, your connections, your options
Your train is late. Does the connection still hold? And if not, what is left? Quai à Quai answers with SNCF open data, live, with no account. For trains in France.
What you can ask it
Where is my train?
Type its number. You see its route, every stop with the scheduled and the expected time, its delay, and where it is between two stations.
Try with TGV 8560 →Will my train be on time?
Before leaving for the station, a search from your station to your destination shows the next departures with their state on time or +12 min, and the time the SNCF feed last spoke.
When the feed says nothing about a train, Quai à Quai says nothing either. Silence is never shown in green.
Try Bordeaux → Paris →Does my connection hold?
Every change of train carries its verdict: holds — 18 min of margin, tight — 3 min of margin or probably not held, 7 min short. The margin is recomputed with today's delays, and the verdict says what it rests on: live data for both trains, or the timetable alone.
Try Bordeaux → Lyon →My train is late, what do I do at the station?
From the station you are in, to your destination: the possible journeys, direct or with a change, sorted by arrival time. The first in the list is the one that gets you there soonest, not the one that leaves first.
Try Lyon → Marseille →I missed my connection, what are my options?
Under the connection that does not hold, the other possibilities: get off earlier, change elsewhere, wait for the next one, each with its arrival time and the gap from the plan. And a link to send to whoever is waiting for you: they see the same journey, followed live.
Boarding a train that was not on your ticket requires the on-board staff's agreement. Quai à Quai shows what is running, never a right to board it.
What it is, and what it is not
- A decision aid, not an authority. What railway staff, ticket inspectors and station displays say always prevails.
- SNCF Voyageurs' open data, read from transport.data.gouv.fr: the timetable and the live feed. TGV INOUI, OUIGO, Intercités, TER, Lyria, ICE.
- No account, no cookie, no tracker. A journey fits entirely in its link. Your position, if you allow it, is used to find nearby stations and is stored nowhere.
- No sales. No tickets, no reservations, no advertising. The site is neither published nor endorsed by SNCF.
Frequently asked questions
Does Quai à Quai sell tickets?
No. It sells nothing and books nothing. It shows the trains that are running and your options; tickets, exchanges and reservations are the carrier's business.
Which trains are covered?
Those in SNCF Voyageurs' open dataset: TGV INOUI, OUIGO, Intercités, TER, plus Lyria and the Deutsche Bahn ICE trains serving France.
Are the delays shown reliable?
They come from the live feed published by SNCF, whose last update time is shown on every screen. That feed covers only part of the trains: when it says nothing, Quai à Quai says nothing either, and never shows a train as on time unless it was announced.
What do “holds”, “tight” and “probably not held” mean?
It is the verdict on a connection: the margin between one train's arrival and the next one's departure, once the required transfer time is taken off. “Holds” is shown only when both trains are watched live; otherwise the margin is given on the timetable.
Can I board a train other than the one on my ticket?
Only with the on-board staff's agreement. The options shown describe trains that are running, not a right to board them.
Do I need an account? Am I tracked?
No. No account, no measurement cookie, no tracker. The server keeps its logs for fourteen days, for security and aggregated usage statistics, and nothing else.
Where does the data come from?
From open data published by SNCF Voyageurs on transport.data.gouv.fr, under the ODbL licence. The sources are detailed in the legal notice.
