Does Eurostar have a luggage size limit?

Eurostar asks that bags fit in the overhead rack or under the seat. The practical limit cited is 85 cm for the longest dimension. There is no enforced weight limit for carry-on bags, but you must be able to lift your own luggage.

Are there liquid restrictions on European trains?

No. Unlike air travel, European trains do not have the 100ml liquid rule. You can carry full-size bottles of water, wine, toiletries, or anything else in your bag without restriction.

Do you go through security screening on European trains?

On most European trains, including domestic services and InterRail routes, there is no security screening. Eurostar is the main exception — it operates airport-style security at London St Pancras, Brussels-Midi, Paris Gare du Nord, and Amsterdam Centraal.

Where do you store luggage on overnight trains like Nightjet?

Nightjet and other couchette trains have under-seat storage in compartments, small overhead racks, and a luggage area at the end of the carriage. In private sleeper compartments, bags go in the overhead rack or under the lower bunk. Lock or keep valuables close when sleeping.

Is it better to take the train or fly in Europe if you have only a carry-on?

For city-centre to city-centre journeys under 4 hours, the train is often faster door-to-door than flying. With a carry-on only, you skip baggage claim entirely on trains and avoid airline liquid rules — train travel is consistently the smoother experience for carry-on travelers.

Carry-On Luggage on European Trains: What You Need to Know

Travelling Europe by train with a carry-on bag is one of the most frictionless travel experiences available. No liquid restrictions. No overhead bin anxiety. No bag fees. No baggage claim. But different train services have different storage setups, and a few — particularly Eurostar — have rules worth knowing in advance. Here is what to expect on the major European rail networks.

Eurostar: The One European Train with Rules

Eurostar is the cross-Channel high-speed service connecting London with Brussels, Paris, and Amsterdam. It operates more like an airline than a typical train, including passport control and security screening at departure stations.

Eurostar luggage policy:

2 pieces of luggage allowed, plus 1 small personal item
Bags must fit in overhead racks or under the seat
The longest dimension should be under 85 cm
No weight limit, but you must be able to lift your bags yourself
Oversized items can be sent separately via Eurostar's registered luggage service

Security at Eurostar:

Full airport-style screening at London St Pancras, Brussels-Midi, Paris Gare du Nord, and Amsterdam Centraal
Liquids in hand luggage must follow the 100ml in a 1-litre bag rule (same as air travel) at Eurostar only
Laptops come out of bags, as at airports
Arrive at least 30 minutes before departure; 45 minutes is recommended for busy travel days

The Eurostar security process is the main exception to the train travel rule that your bag is your business. On all other major European services, you walk on and find your seat.

TGV, Thalys, and ICE: Overhead Racks and End-of-Car Storage

France's TGV, the Belgian Thalys (now Eurostar's international brand), and Germany's ICE are the backbone of European high-speed rail.

Storage on these trains:

Overhead racks above each seat — suitable for bags up to roughly 50 x 35 cm in the lateral dimension
Large luggage areas at the end of each carriage, before the door vestibule — accommodate larger bags, suitcases, and bicycles
No official size or weight limits on most routes, but bags must be manageable by you alone

For carry-on-only travelers, overhead racks are usually fine. If your bag is a 45L+ travel pack, use the end-of-car area and keep valuables in a day bag with you.

No liquid restrictions: on TGV, ICE, and Thalys services, carry whatever you like in your bag. A full bottle of wine, a large sunscreen, a litre of water — all fine. This is one of the most overlooked advantages of train travel for carry-on packers who normally travel by air.

InterRail and Eurail: No Official Limit

InterRail and Eurail passes cover domestic and international routes across Europe. There is no official luggage limit for InterRail or Eurail passengers because the pass simply determines your ticket entitlement — the luggage rules are set by each individual operating carrier.

In practice, this means:

On most regional and domestic trains in France, Germany, Italy, Spain, and the Netherlands: no enforced limit, no security, no liquid rules
On Italian Frecciarossa and Frecciargento: overhead racks plus end-of-car storage, no official limits
On Spanish AVE: bags in overhead racks, no security screening for domestic services
On regional trains in Eastern Europe: storage in the overhead rack or under the seat; corridors on older rolling stock are narrow, so very large bags can be awkward

The practical limit for InterRail travel is not a rule but a physical one: if your bag does not fit in an overhead rack and the end-of-car area is full, you are standing in the vestibule with your luggage. A carry-on that fits comfortably in an airline overhead bin (55 x 40 x 20 cm range) handles every European train setup comfortably.

Flying vs Train with a Carry-On: The Comparison

Door-to-door time on routes under 4 hours (e.g. Paris to Lyon, London to Brussels, Berlin to Amsterdam):

Train: arrive 15–30 minutes before departure, no security on most routes, station in city centre, arrive at destination city centre station
Flight: arrive 90 minutes before, security queuing, boarding, taxi to airport, taxi from airport, baggage claim if checking (not applicable for carry-on only)

For city-pair distances where the high-speed train journey is 2–3.5 hours, the train is typically faster door-to-door and significantly less stressful for carry-on travelers.

Advantages of train travel for carry-on packers:

No liquid restrictions (except Eurostar)
Bags stay with you, visible, in the cabin at all times
No overhead bin anxiety — end-of-car storage has space for large bags
No gate check risk — no one is measuring your bag
No fees for a second bag on most rail services

When flying beats the train:

Distances over 5–6 hours where overnight train is not available
Budget flight prices that substantially undercut rail
Routes not covered by rail (island destinations, remote cities)

Overnight Trains: Nightjet and Couchette Services

Nightjet (operated by Austrian Federal Railways) is the main branded overnight train network in Europe, connecting Vienna, Berlin, Zurich, Brussels, Paris, and Rome among others. Other operators run couchette cars on various routes.

Storage on Nightjet:

Couchette compartments (6-bunk): bags go under the lower bunks or in the overhead net
Sleeper compartments (2–3 bunk private): larger overhead rack and space under the lower bunk
End-of-car luggage area: for large bags and suitcases

Security on overnight trains:

No security screening
Passport control happens at border crossings, often while you sleep — a conductor collects passports in the evening and returns them in the morning
Keep your passport accessible (not buried in your bag) when crossing international borders overnight

Carry-on tips for overnight trains:

Use a small padlock on your main bag's zipper for peace of mind when sleeping in shared couchette compartments
Keep a day bag or personal item with valuables (passport, wallet, phone) under your pillow or in your berth with you
A 40–45L bag fits under the lower bunk in most couchette and sleeper compartments; anything larger may need the end-of-car rack where it is not immediately visible from your berth
