Not all European trains need seat reservations. Whether you need one depends on the train type, the operator, and whether you are travelling with a rail pass or a point-to-point ticket. Get this wrong in either direction: board a train without a required reservation and you may be turned away, or pay fees on trains where you can simply sit down.
Seat reservation requirements by train type
High-speed trains, including the Eurostar, TGV, and AVE, require reservations on every journey. No exceptions. You must have an assigned seat before you board, whether you hold a rail pass or a separate ticket.
Night trains also require reservations. You are not just claiming a right to board. You are booking a specific accommodation type: seat, couchette, or private sleeper.
Regional and local trains rarely require reservations. Most InterCity trains sit somewhere in between, with reservations optional or recommended but not enforced.
Always check the booking page for your specific train, not the category. Rules vary between operators and sometimes between routes on the same service.
Rail pass holders: how reservations work
If you travel with an Interrail Pass or Eurail Pass, the pass covers the journey but not the seat. On trains that require reservations, you pay a separate reservation fee on top of your pass.
Fees vary considerably by operator:
| Train service | Reservation required? | Pass-holder fee (2nd class) |
|---|---|---|
| Eurostar (continental routes) | Yes, compulsory | EUR 32 Standard / EUR 37 Plus |
| Eurostar (London routes) | Yes, compulsory | EUR 35 Standard / EUR 40 Plus |
| TGV (France domestic) | Yes, compulsory | EUR 10 to EUR 20 |
| ICE (Germany domestic) | Optional or recommended | EUR 5.50 |
| Frecciarossa / Trenitalia (Italy) | Yes, compulsory | EUR 13 |
| AVE (Spain domestic) | Yes, compulsory | EUR 10 (Elige) |
| ÖBB Railjet (Austria) | Recommended | EUR 3 |
| Night trains (Nightjet etc.) | Yes, compulsory | Varies; average EUR 20 |
Italy needs a separate mention. Trenitalia Frecciarossa reservations are EUR 13 and compulsory for pass holders. Italo, Italy’s other high-speed operator, does not accept Interrail or Eurail passes. If you are using a pass in Italy, you must travel with Trenitalia.
If you hold a point-to-point ticket, the seat reservation is usually bundled in on trains where it is compulsory. No separate fee.
Booking pass-holder seat reservations
The Eurail and Interrail self-service tools at eurail.com and interrail.com cover most major European routes. Log in with your pass, pick your trains, and pay the fee there. Booking directly through these tools avoids the service charges that third-party platforms add on top.
For Eurostar, book through the Eurostar site or the Eurail/Interrail self-service tool.
Station ticket counters work in most countries too. Slower, but a useful option if a service is not available online.
Reservation rules by country
Spain
AVE reservations are compulsory. Pass-holder fees depend on the class: EUR 10 for Elige (2nd class) and EUR 13 for Elige Confort (1st class).
Book online at renfe.com, through the Renfe app, or at station counters. Renfe also offers pre-reservations on some services, where you hold a seat for up to 72 hours before paying at a station. This is a Renfe-specific feature, not something you will find across Europe.
Germany
DB ICE seat reservations are optional on domestic routes. You can board without one, though trains fill quickly in summer and around public holidays. A reservation costs EUR 5.50 in 2nd class, EUR 6.90 in 1st.
If you want a specific seat, a quiet car, or a family car, book through DB’s website, the DB Navigator app, or a station ticket office.
A direct ICE between Berlin and Paris launched in December 2024. Journey times run around eight hours. Reservation fees on that international leg are higher than domestic ICE, around EUR 19.
France
TGV reservations are compulsory, including for pass holders. Fees typically range from EUR 10 to EUR 20 depending on the route. Book at sncf-connect.com or at SNCF station counters. Most TGV booking windows open four months ahead.
Regional TER trains do not require reservations. Board and take any free seat.
Italy
Trenitalia Frecciarossa and Frecciargento services require reservations. Pass holders pay EUR 13 per journey in both 2nd and 1st class.
Do not board an Italo service with an Interrail or Eurail Pass. Italo does not accept them. The high-speed routes between Rome, Florence, and Milan are served by both Trenitalia and Italo, so check which operator runs your train before booking. You need a Trenitalia service.
Austria and international routes
ÖBB Railjet services recommend reservations for EUR 3 but do not enforce them domestically. On the Brenner corridor between Munich, Innsbruck, Verona, and Venice, a mandatory supplement applies on top of the reservation fee.
Eurostar services from Amsterdam, Rotterdam, Brussels, and Paris to London require reservations, no exceptions. Pass-holder supplements on London routes are EUR 35 in Standard and EUR 40 in Plus.
Night trains
Night train reservations are always required. You are booking an accommodation type, not just a seat number. Seats are the cheapest, in a reclining car shared with other passengers. Couchettes are fold-down bunks in a compartment of four or six, and most travellers choose these. Private sleepers give you your own compartment, sometimes with washing facilities.
Couchettes and sleepers sell out well before departure on popular routes. Book when the window opens, often two to three months ahead for peak travel periods.
Average reservation costs are around EUR 20, but vary by route, operator, accommodation type, and how far ahead you book.
Tips for booking
Pass-holder quota seats on Eurostar and TGV are limited. Once they are gone, you need a full-price point-to-point ticket. Most booking windows open three to four months ahead, so book early if you know your dates.
Use eurail.com or interrail.com for pass-holder reservations. Both avoid the service charges that booking agents add.
Use the right booking channel for each country. DB’s website or Navigator app for Germany; renfe.com for Spanish AVE; sncf-connect.com for French TGV; trenitalia.com for Italian Frecciarossa. Each operator’s own site is the most reliable place to start.
For night trains, decide on the accommodation type first. Couchettes and sleepers sell down faster than seats, and have different prices. If the better options are gone, you end up with a seat.
On regional trains, skip the reservation. Most do not need one. Just board and find a free seat.
Frequently asked questions
Do TGV trains require seat reservations?
Yes. TGV reservations are compulsory, including for Interrail and Eurail pass holders. Pass holders pay a separate reservation fee on top of their pass, typically between EUR 10 and EUR 20 depending on the route. Pass-holder places are limited, so once the quota sells out, you need a full point-to-point ticket instead.
How far ahead can I book a European train reservation?
Most major high-speed train booking windows open three to four months before departure. TGV bookings at SNCF typically open four months ahead. Pass-holder quota seats on popular services fill quickly once the window opens, so book as early as the schedule allows if you have fixed dates.
How much does a seat reservation cost on a European train?
Reservation fees vary by operator and train type. For Interrail and Eurail pass holders, common fees include: Eurostar continental routes EUR 32 in Standard and EUR 37 in Plus; Eurostar London routes EUR 35 in Standard and EUR 40 in Plus; TGV in France EUR 10 to EUR 20; ICE in Germany EUR 5.50 in 2nd class; Frecciarossa in Italy EUR 13; AVE in Spain EUR 10 for Elige (2nd class). Night train reservations average around EUR 20 but vary by accommodation type and route. If you have a point-to-point ticket on a compulsory-reservation train, the seat reservation is usually included in the fare.
Can I make a pre-reservation on European trains?
Pre-reservations are a Renfe-specific feature in Spain. When booking an AVE by phone or some online channels, you can hold a seat for up to 72 hours before paying at a station. This option is not widely available across Europe. Other operators do not generally offer this kind of temporary hold.
Do night trains require reservations?
Yes, always. On night trains you are not just reserving a seat number but booking an accommodation type: a seat in a reclining car, a couchette in a shared compartment, or a private sleeper. Each category has different pricing. Couchettes and sleepers sell out faster than seats on popular routes, sometimes two to three months before departure on peak-period trains. Book as early as the window opens if you want a bed.
Does Italo accept Interrail and Eurail passes?
No. Italo does not accept Interrail or Eurail passes. If you are using a rail pass in Italy, you need to travel with Trenitalia. Both Trenitalia and Italo serve the main high-speed routes between Rome, Florence, and Milan, so check which operator runs your specific train before you book. Only Trenitalia Frecciarossa and Frecciargento services are valid for pass holders.
Do I need a separate seat reservation if I have a point-to-point ticket?
Usually not. On trains where seat reservations are compulsory, the reservation is bundled into a point-to-point ticket and you pay one combined fare. You only pay a separate reservation fee when you are travelling with an Interrail or Eurail pass, because the pass covers the journey but not the seat.
