French Train Strikes and How to Keep a Slow Trip Moving

You booked a slow week of regional trains, and now the news says the rail unions have called a grève for Thursday. French train strikes are common enough that most travellers who spend a month here will meet at least one, and the good news is that they rarely stop a trip outright if you know how the system announces them and what still runs.

I have been caught by strikes in Brittany, the Jura and twice in Occitanie. Each time the difference between a lost day and a slightly slower one came down to the same handful of habits, and they are below.

How French train strikes are announced

French law requires transport unions to file a strike notice, the préavis, at least five days before action begins. That means a strike is almost never a surprise on the morning itself. The notice is usually reported in the national press the same day it is filed, often with the dates and which part of the network is involved: TGV, Intercités, TER, or one region only.

The more useful rule comes later. Since 2007, individual rail workers who intend to strike must declare it to their employer 48 hours ahead. This lets SNCF publish a reduced timetable, called a plan de transport adapté, by 17:00 the day before each strike day. Until that timetable appears, any prediction is a guess. Once it appears, it is reliable: trains listed on it generally run, and trains missing from it do not.

Five or more days before: the préavis is filed and dates become public.
Two days before: staff declarations close and SNCF knows its numbers.
17:00 the day before: the adapted timetable is published on the SNCF Connect app and regional TER sites.

What usually keeps running during a strike

Strikes are not all or nothing. A national strike might cut TGV services to one in two, Intercités to one in three and some TER lines almost to zero, while other regions run close to normal. Regional TER services depend on local staff, so the picture can vary wildly. During one strike day in 2023, Normandy ran most of its trains while neighbouring Brittany ran a skeleton service.

Service	Typical strike day picture	Your best move
TGV INOUI	Often 50 to 75 percent of trains, prioritised on main routes	Check the adapted plan, exchange to a running train for free
Ouigo	Run by separate crews, often less affected	Keep your booking but still check at 17:00
Intercités	Frequently the hardest hit	Plan a bus or car alternative early
TER regional	Varies by region, sometimes replaced by coaches	Look at the regional TER page, not national news
Local buses and coaches	Usually run, separate operators	Book seats early, they fill fast

If you depend on regional lines, our guide to TER regional trains for slow travel without a car explains how the regional networks are organised and where each one posts its own disruption notices.

Your rights to refunds and exchanges

When SNCF cancels a train during a strike, you are entitled to a full refund or a free exchange, even on non-refundable fares. In practice this usually happens automatically by email once your train is removed from the timetable, and the app offers alternatives. For TER tickets, which are often bought at the machine on the day, keep the ticket: the regional operator will refund unused tickets at the counter or through its online form.

What you are not entitled to is compensation for the hotel night you lose because you cannot reach it. Travel insurance sometimes covers this, but many policies exclude "foreseeable" strikes announced before you booked. Read your policy for the word grève or industrial action before relying on it. This is also a reason to book small hotels directly, since owners who know you are stuck often move a night without charge, which is one of the points in our piece on booking direct at small French hotels.

Why I do not rebook everything the moment a strike is announced

The common advice online is to cancel your train plans as soon as you hear the word strike and rent a car. I think that is usually a mistake, for three reasons.

First, notices are frequently filed for long windows, sometimes weeks, and actual participation drops after the first day or two. A préavis covering ten days often means one hard day and nine near normal ones. Second, cars booked in panic are expensive. On a strike week in a provincial town, a small rental for three days can jump from about 120 euros to over 300, and one-way drop fees across regions add 60 to 150 euros more. Third, giving up your rail booking early can cost you the right to the free refund, because you cancelled before SNCF did.

The better move is to wait for the 17:00 timetable the day before, keep a fallback in mind, and only switch if your train is genuinely missing.

A strike day plan that works

Turn on notifications in the SNCF Connect app for every booked journey, and bookmark the TER page for the region you are in.
Build slack into the trip. On slow itineraries, a free half day every four or five days absorbs a strike without breaking anything.
Pick the earliest running train. On strike days the first and last trains of the adapted plan are often packed, but mid-morning departures can fill completely. Arrive at the station 30 minutes early.
Know the coach option. BlaBlaCar Bus and FlixBus cover many intercity links, often for 10 to 25 euros, and regional coach networks fill gaps between market towns.
Carry food and water. Station cafés can close when staff strike too, and a train that leaves at 14:10 can mean missing lunch entirely in a place where kitchens shut early, as covered in our note on lunch hours in rural France.
Stay put if the gap is small. If your destination is 40 km away and nothing runs, one more night in a town you already like is often the best travel of the trip.

Days to watch are the start of school holidays and the weeks around pension or budget debates in parliament, when national action is more likely. Summer Sundays in August are rarely touched.

Frequently asked questions

How do I know if there is a train strike in France tomorrow?

Check the SNCF Connect app or the regional TER website after 17:00 the day before. That is when SNCF publishes the adapted timetable showing which trains will run. News stories before that only tell you a strike is planned, not which trains it will cancel.

Will I get a refund if my train is cancelled by a strike?

Yes. If SNCF cancels your train, you can claim a full refund or a free exchange, including on fares that are normally non-refundable. Do not cancel the ticket yourself before the train is removed, or you may only get the standard fare conditions.

Do strikes affect Paris metro and RER trains too?

Sometimes, but they are separate. The metro and most RER lines are run by RATP, whose unions file their own notices. A national SNCF strike can still disrupt RER lines C, D and E and suburban Transilien services, so check both operators if you start or end your trip in Paris.
