Train Luggage in Europe: The 2026 Rules, Operator by Operator

Short answer: contrary to a stubborn myth, European rail is no longer a luggage free-for-all. In 2026, Eurostar limits each traveller to two bags of up to 85 cm + one accessory, SNCF allows three bags, two of them large (max. 90 × 70 × 50 cm), and applies a flat €50 penalty for oversized or unlabelled luggage on TGV Inoui, Intercités and Ouigo. Renfe thinks in weight (3 items, 25 kg total on AVE), Trenitalia in dimensions (2 large bags on Frecce trains), while ÖBB and Deutsche Bahn remain the most relaxed, sticking to a "if you can carry it yourself, you can board with it" principle. Bikes, skis and musical instruments almost everywhere require a separate paid reservation (€5 to €30). The rule that saves you: a tag with your first and last name on every bag, mandatory in France, plus a suitcase that stays under 90 cm tall.

There's a precise moment when train travel loses its charm: when you board a packed coach 12 on a TGV at Paris-Montparnasse with a 75-litre suitcase and the three racks at the end of the carriage are already full. That moment has become more frequent since long-distance rail took over a slice of air traffic — with the same amount of luggage… but without the holds.

Operators have reacted. Since 2022, SNCF has introduced a framework with actual numbers where custom once ruled; Eurostar tightened its checks after merging with Thalys; Renfe and Ouigo España apply fee scales inspired by low-cost airlines. The result: a traveller doing Paris → Barcelona → Milan → Vienna crosses four different luggage regimes in three days. Here's the full map, operator by operator, with the real amounts and the traps.

1. Why the railways started counting suitcases

The official justification is twofold: safety and capacity. A bag blocking an aisle or a gangway door is an obstacle in the event of evacuation — the point most often raised by national rail safety authorities. And a TGV Duplex, unlike an Airbus A320, has no hold at all: everything that comes aboard stays in the passenger space.

The second reason is more prosaic. Modern trainsets were designed to maximise seat count. On the latest generations of high-speed stock, the luggage areas at carriage ends have been redistributed or rethought, and the overhead racks rarely take more than an airline-sized cabin bag. The luggage-per-passenger ratio worsened at the very moment when the "long-distance international" clientele — the ones travelling with real suitcases — was growing.

Hence the third reason, rarely stated out loud: commercial clarity. An operator that caps luggage can sell a supplement. Ouigo España, Iryo and Ouigo France worked that out before anyone else.

2. France: SNCF Voyageurs, Ouigo and the €50 flat penalty

TGV Inoui, Intercités and TER

SNCF's conditions of carriage provide, per traveller:

Two points matter more than the centimetres:

1. Labelling is mandatory. Every bag must carry the traveller's first and last name, legibly and securely attached. It's the most frequently ignored rule and the easiest to check. A simple rigid luggage tag with a name holder does the job, and spares you both an argument with the conductor and the loss of your bag.
2. The penalty is real. For an oversized bag, an unlabelled one, or one left in an obstructive spot, a flat €50 charge can be applied, separate from the fine for travelling without a valid ticket. In practice, conductors favour a warning — but the regulatory basis exists, and enforcement campaigns do happen during peak periods.

Ouigo: the outlier

Ouigo, SNCF's low-cost brand, runs on an explicitly airline-style model. The base fare includes one personal item + one cabin bag. An additional large bag costs extra (around €5 to €20 depending on when you buy, more expensive on board or at the station than online). Add it at the time of booking: the supplement bought at the station is always pricier.

The same principle applies to Ouigo España on the Madrid–Barcelona, Madrid–Valencia and Málaga–Barcelona routes, with fee scales specific to the Spanish market.

Key takeaway: on Ouigo, the suitcase isn't banned, it's priced. That €19 headline fare can therefore climb by 30% if you're away for two weeks.

3. Eurostar: the strictest regime in Western Europe

Since Thalys was folded into the Eurostar brand, a single set of rules applies to the London, Paris, Brussels, Amsterdam, Cologne and Dortmund services:

• 2 bags per traveller in Standard class, maximum length 85 cm per bag;
• + 1 small accessory (handbag, laptop);
• 3 bags in the higher classes (Plus / Premier);
• 1 bag only for children under 4.

Name labelling is also required, and the X-ray screening at boarding (mandatory for Channel crossings) makes enforcement far more systematic than elsewhere. An extra or oversized bag can be refused or incur a supplement at check-in.

It's also the route with the longest boarding time: allow 45 to 90 minutes before departure at London St Pancras or Paris Gare du Nord depending on the season. A TSA combination padlock saves you from opening and closing a suitcase under the gaze of the queue if a manual check is requested.

4. Spain, Italy, Austria, Germany: four philosophies

Renfe (AVE, Avlo)

Spain is the only major network that thinks in weight: on AVE and long-distance trains, the rule is 3 items maximum for a combined 25 kg (with a capped sum of the three dimensions, generally 290 cm). On Avlo, the low-cost offer, the base allowance is tighter and extra bags cost money. An electronic travel luggage scale fits in a side pocket and will tell you in ten seconds whether you're over 25 kg — handy on the way back too, once the suitcase has gained three kilos of jamón.

Trenitalia and Italo

On the Frecciarossa, Frecciargento and Frecciabianca, the principle is two reasonably sized bags that the traveller must be able to handle alone, plus a piece of hand luggage. Frecciarossa 1000 sets have luggage racks at the carriage ends, which fill up fast on Friday-evening Rome–Milan departures. Italo follows a similar logic, with a welcome tolerance for large formats in Prima and Club Executive.

Watch out, though, for Italian Regionali: no formal limit, but narrow aisles and no dedicated space. On a Naples–Salerno at rush hour, a big suitcase is a genuine handicap.

ÖBB (Austria) and Deutsche Bahn (Germany)

These are the two most relaxed networks in Western Europe. The rule rests on a simple principle: you board with what you can carry and stow on your own, without getting in anyone's way. No counting suitcases, no weighing. In return, DB has invested heavily in structured luggage areas on the ICE 4 and ICE 3neo, and ÖBB offers a door-to-door luggage service (Gepäckservice) that lets you have a suitcase shipped separately — handy for a ski trip or a point-to-point hike.

5. Night trains: the real 2026 headache

With the mass return of overnight services — ÖBB Nightjet, European Sleeper, Snälltåget, the new Nordic corridors — luggage has become a central issue. A night train combines three constraints: limited floor space, darkness, and close neighbours.

What you need to know:

• In a 4- or 6-berth couchette, storage comes down to a compartment under the lower bunk and a shelf above the door. A 75-litre hard-shell case often won't fit. A soft wheeled holdall slides into spaces where a hard shell simply jams.
• In a reclining seat, the bag stays with you: the most restrictive regime of all.
• In a private cabin (Nightjet Mini Cabin, European Sleeper rooms), space is decent but the door is narrow.
• Security: shared compartments lock from the inside on most modern Nightjet stock, but not always on older Central European rolling stock. Keeping your passport, cash and phone on you remains the rule. A hidden travel money belt or a neck pouch settles the question without you having to think about it.

Night operators generally impose no numerical limit, but they refuse bulky items that haven't been reserved (assembled bike, surfboard, furniture).

6. Bikes, skis, instruments: the special regime

This is where improvising costs the most, because reservation is almost always mandatory and limited in the number of spaces.

On heavily booked routes (Nightjet services to Italy, German regional trains along the Rhine, Austrian lines in summer), bike spaces sell out weeks in advance. Book them when you buy the ticket, never afterwards. A folding-bike carry cover turns the problem into a non-issue: folded and zipped into its cover, the bike becomes ordinary luggage on almost every network.

7. Loss, theft, damage: what European law says

Regulation (EU) 2021/782 on rail passengers' rights, applicable since 7 June 2023, does not treat luggage the way air transport does. The essential point: your hand luggage remains in your care. The operator is liable only where its own fault is proven, or where it has taken charge of the bag (check-in service, accompanied luggage such as ÖBB's Gepäckservice, left-luggage office).

In practice:

• Bag left on board → the operator's or station's lost property office. In France, SNCF centralises lost property and charges retrieval/storage fees; allow several days.
• Theft on the train → file a report with the police of the country where the theft occurred; cover depends on your home insurance (holiday/away-from-home cover) or your bank card's insurance.
• Damaged checked luggage → claim with the operator, within the time limits set out in the contract of carriage.

It's precisely because the operator's liability is limited that physical precautions matter: a Bluetooth tracker slipped into the suitcase, a photo of the bag's contents before departure, and never a suitcase left alone at the far end of a crowded carriage.

8. Seven habits to never pay a supplement

1. Stay under 90 cm in height. A "large airline format" suitcase (55 cm) and a medium one (65–70 cm) pass everywhere in Europe, Eurostar included (85 cm max).
2. Label everything, even the backpack. It's free, it's mandatory in France, and it's your only chance of getting a forgotten bag back.
3. Choose soft over hard-shell for night trains and regional services: volume compresses, shells don't.
4. Buy Ouigo/Avlo supplements online, never at the station or on board.
5. Stand at the right spot on the platform. Luggage areas are at carriage ends: find your coach number on the train composition screen and aim for the door nearest the rack rather than the one nearest your seat.
6. Book the bike space at the same time as the ticket. Never afterwards.
7. Travel light on journeys with multiple connections. Two platform changes in ten minutes in Zurich or Milan with 25 kg means a missed train.

9. 2026 summary table

In summary

The train remains, by some distance, Europe's most generous mode of transport when it comes to luggage: two free suitcases where a low-cost airline charges €40 for one. But unlimited tolerance is a thing of the past, and the gaps between operators are widening — low-cost rail is importing low-cost aviation's codes, while Germany and Austria stick to the historic model.

The winning strategy in 2026 fits in one sentence: size your luggage for the strictest operator on your itinerary. If your trip includes a Eurostar or a Ouigo segment, that's the one setting the rule for the whole journey. Everything else follows effortlessly.

The rules and prices mentioned are those published by the operators (SNCF Voyageurs, Eurostar, Renfe, Trenitalia, ÖBB, Deutsche Bahn) and are subject to change. Always check the conditions of carriage in force at the time of booking.
