Getting to Brest by train

... anyway, even at the last minute: a survival guide

Some higher executives at the SNCF and consorts are apparently working very hard to make train travel as inconvenient as air travel is nowadays: mandatory booking for almost all long-distance lines (which means named tickets and travelling with valid ID documents, and mandatory additional booking fees), yield management (resulting in sold out and/or more expensive travels), exchange and refund restrictions, luggage restrictions, a low-cost offer with even more restrictions, fees and voluntary inconveniences, and websites and apps that have reliably qualified as industrial disasters for about as long as the SNCF has published websites and apps. So far these policies seem to have mostly benefited on one side to coach operators, which are not exactly ideally convenient either, and low-cost airlines on the other side, no wonder one of them is now the 3rd world-wide airline in number of passengers, 7th in fleet size and 5th in number of daily flights.

So let's beat these awful guys. The guide below will help you to plan your train travel to Brest via alternative routes in case of traffic disruptions, or if the mainline trains are all sold out, or if you miss a train and can't change your mandatory reservation to a later one because they are all sold out, or if you would like to avoid a transfer through Paris. Now you have no excuse.

Always double-check with informations from official sources as the data below may contain errors, get out-of-date or temporary disruptions may be scheduled.

Planning your trip

For planning your trip the interrail/eurail trip planner is a convenient tool even if you are not an interrail/eurail pass holder, as they show all trains and allow you to exclude trains with mandatory booking from the results. Just keep in mind that their schedules are only updated weekly, so the latest changes or cancellations may not show up.

Map of the european passenger trains network (note that some regional routes are missing from that map)

Another useful but untranslated tool that doesn't need JS (excepted for the OSM-based maps): https://signal.eu.org/rail/ though some schedules (typically regional trains in some areas) can be missing or out of date.

The two links below will display scheduled times using your browser or device current timezone, which may be different than the French legal time (CEST/UTC+2).

Other SNCF websites (though not all of them) are known to be affected by similar issues.

Map of IC and night trains routes

When planning a connection, keep in mind that according to historical data your first train has about 1 out of 4 chances of arriving more than 5 minutes late, with an average delay that is around 10 minutes.

Alternative booking websites

1.2.Train

This vintage-looking website (and future app) is run by a single guy and already sells almost 12000 tickets a month. Although it is not yet translated it has a very simple interface that makes it easy to search and buy French (excepted ?OuiGo) and Eurostar train tickets. There is no shopping cart (yet?), so one needs to complete a payment transaction for each trip. There is, notably, no additional booking fee (which is why OuiGo trains are not sold there). Some promotional offers can be found on its mastodon feed.

railfinder.eu

railfinder.eu opened very recently and is still in beta. See their how it works page for current features and caveats. Basically they use a custom search algorithm that prioritizes comfort and night trains. They typically add a 10% booking fee.

Estimating and limiting the cost

Maximum fares

Here are the estimated maximum fares to Brest, one-way, one person, 2nd class, transfer through Paris, from:

Eurail/Interrail passes

If you're not a French resident, an interrail or eurail single-country or global pass is likely to be the best deal you can get. One downside is that there is a limited amount of places available to pass holders in French trains, and most long-distance French trains travelling even in week days in July tend to be full weeks before departure date. Another downside is that it won't give you access to Transilien (Paris area) and Ouigo trains, you will have to buy tickets separately if you wish to travel with these.

Children aged 4 to 11 may travel with a free Child Pass. A child must be accompanied at all times by at least one person with an Adult Pass. Up to 2 children can travel with 1 adult.

Costs, as of 2025-04-20:

SNCF cards and subscriptions

https://www.sncf-connect.com/app/catalogue

An Avantage card costs 49 €, is valid for one year and will give you an immediate 30% rebate on return trips including at least one week-end night (friday, saturday or sunday), so the break-even point for buying one is reached at 163.34 €. With that card prices are also capped depending on travel time so the final rebate may end up being more than 30%.

An additional adult traveling together with the card holder may also benefit from the 30% rebate, as well as up to 3 children (less than 12 years old).

Examples:

Applicability on regional (TER) networks is ... complicated. Assuming the card holder is an adult over 30, regions Bourgogne-Franche-Comté, Centre-Val-de-Loire, Nouvelle-Aquitaine, Occitanie, Provence-Alpes-Côte-d'Azur do not offer reduced fares for these card holders. Other regions offer up to 50% (but typically 25% or 30%) rebates to the card holder and another (optional) adult travelling together, no additional reduced fares for children excepted for Pays-de-la-Loire. In addition, the reduced fare is only offered for a return trip including a week-end day or night, excepted for the regions Grand-Est, Haut-de-France (no constraints) or Normandie (no constraints in non-bookable TER). An overview of the situation (possibly outdated) is available by following this link (PDF, french only).

Ouigo trains

https://en.wikipedia.org/wiki/Ouigo

This is a third-class "low-cost" service with additional voluntary inconveniences and increased passenger density. Not part of the interrail/eurail network. Tickets can only be bought online (not in the stations) or through some travel agencies (additional booking fees may apply).

Ouigo trains are labelled OGV (Ouigo Grande Vitesse) or OTC (Ouigo Train Classique) in the timetables below.

Night trains

To Paris-Austerlitz from France

https://www.sncf-connect.com/article/5-destinations-desservies-par-le-train-de-nuit

With possible connections from Spain

With possible connections from Spain or Italy

International night trains

To Offenburg and Basel

Connections to Strasbourg and Paris.

To Brussels-Midi

Connections to Lille and Paris.

To Strasbourg and Paris-Est

To Irún/Hendaye

Unfortunately the convenient international night train service between Lisbon and Hendaye is still "suspended" while there are ongoing modernization works on the track (see https://www.cp.pt/passageiros/pt/descontos-vantagens/em-destaque/beira-alta); there is currently no passenger train service between Portugal and Spain on that line.

From the UK or IE

There is no Eurostar night service planned in July.

Ferry services to Roscoff (no train service there), St Malo, Cherbourg or Caen are worth considering as they are usually overnight.

Getting out of Paris without a reservation

From Montparnasse station

This is the most direct route to Brest:

paris-montparnasse → le mans 37.40 €
le mans → rennes 30.00 €
le mans → laval → rennes
rennes → brest 29.00 €

Other routes may be interesting if you would like to stop on the way to visit some touristical landmarks:

paris-montparnasse → granville

argentan → le mans → rennes
argentan → granville
granville → rennes

orleans → nantes → quimper → brest

From St Lazare station

Booking (1.50€/1.70€) is required on TNO (TER Nomad) trains when travelling with interrail/eurail passes.

paris st lazare → caen
caen → rennes
caen → granville
caen → argentan → granville

then see above for routes between granville and brest.

Transferring through Paris

Use the RATP website to route your transfer with up-to-date traffic information, then take into account the following:

So definitely don't trust any of the SNCF Connect FAQ pages like this one https://www.sncf-connect.com/aide/correspondances-depuis-gare-du-nord that says it only takes 18 minutes to go from Gare du Nord to Montparnasse. That's only the subway ride time, not including the average wait time and walking time.

In Paris bus-only tickets are a bit less expensive than subway tickets; it's also usually more convenient with luggage (less stairs, as most subway stations don't have elevators) and the view is a bit more pleasant.

To Gare Montparnasse

From Gare du Nord or Gare de l'Est:

From Gare de Lyon:

From Gare d'Austerlitz:

where to eat near Gare Montparnasse?

There is a lot of choice in the station and around, but if you are a bit short (but not too short either) in time, the bistro “L’Express 27” (27 boulevard de Vaugirard, a few steps away to the left from the northeast exit of the station) offers a decent (and typically Parisian bistro-style) plat du jour at a reasonable price, with an all-day and reasonably fast service, and good beers.

Avoiding a transfer through Paris

Below are some suggestions for same-day trips avoiding a transfer through Paris.

From the north

From the north (BE, UK) and flights arriving at LFPG/CDG:

You may also go from CDG-2-TGV to Massy-Palaiseau with the RER B, about 1h10 ride, interval between departures usually less than 10 min, 13 €. This is actually almost fast as the TGV ride around Paris, with similar reliability, but less comfortable, costs an extra ticket (not covered with interrail/eurail passes) and carries more pickpockets.

From the northeast (DE, LX, CH)

Note 1: trains from Strasbourg to Marne-la-Vallée-Chessy that stop at Roissy-CDG will reverse direction there.

Note 2: although this is a less than 10 minutes TGV ride, there is actually no really convenient way to go from Massy to Paris-Montparnasse. Boarding a TGV going that way is not allowed (and nowadays very few of those going there stop at Massy anyway) and the other public transportation options take around 40 to 50 minutes and include a transfer or walking 20 min.

From the east and southeast (CH, IT, SP)

From the southwest (SP)

In case of missed connection

If (and only if) a single train ticket (or eventually multiple tickets paid with the same single transaction, see links below for conditions) involves connection(s) to reach the final destination of that ticket, and one of the trains being late make you miss a connection then the train operator (SNCF) has to offer you to continue your travel, eventually through an alternative route, at no additional cost. If that delay or missed connection would make you at least 60 minutes late on your final destination you have additional assistance and accomodation rights, see EU rail passenger rights below.

Note that normally you can't just hop onboard some next mandatory-booking train with your original ticket: you have to exchange it first, and you probably won't get a guaranteed seat if the next train is already full. However if you are short in time you may try to negotiate access with a ticket inspector on the platform of the departing train.

Also note that non-pass holders travelling with a TGV or IC ticket normally can't board a TER (or any other train) with that ticket even if it's the same route. Same as above, though you are more likely to find a seat, and less likely to find the ticket inspector on the platform (but reach for them as soon as you see them, as you risk getting fined otherwise).

Stranded without accomodation in Rennes?

A popular option is to spend the night in nightclubs until the train service resumes, but that might not be workable on weekdays with luggage.

There are daily night coach services:

You can also search for a ride on the BlaBlaCar carpooling service, this is a popular route and there are usually many departures. A less capitalistic alternative (with AGPL3-licensed source code) is https://www.mobicoop.fr/ but it is also much less popular. If you are travelling with luggage, ask the driver if there will be enough room before booking the trip.
