Missed your connection? There is a rule almost nobody mentions

Your first train runs late. You reach the platform in time to watch your connection pull out. At the counter, someone tells you the ticket you are holding is no longer valid, and that a new one will cost you the price of the journey all over again. Most people pay. There is an agreement between Europe's railways that says, in a lot of these cases, you should not have to. Almost nobody has heard of it, including a fair number of the staff standing behind the counter.

It is called the Agreement on Journey Continuation. It has been in force since 2017, and it is run by the International Rail Transport Committee, the body European railways use to write their common rules. Its own description is honest about what it is: a multilateral agreement between railway undertakings "on a good-will basis". The CIT's information leaflet puts the limit in writing: "this solution does not provide legal rights to passengers." It is a promise between companies, not a right you can enforce. That is exactly why it is worth knowing the name.

What it actually gets you

If you miss a connection on an international journey, the railway whose train you missed should let you "continue their journey at no extra cost on one of the next available trains of the railway undertaking whose service they missed and for which they held a ticket". Read that carefully, because this is the part almost every article about it gets wrong. It puts you on the next train of the same company. It does not entitle you to any company's next departure. Miss the last German ICE of the evening and you cannot demand a berth on an Austrian night train instead. You wait for the next ICE.

It also stops there. The agreement says plainly that it "does not reimburse any costs for hotels, taxis, payments for the ticket or compensations", and it does not promise you a seat, only passage. If the next available train is tomorrow morning, the bed tonight is yours to pay for.

Three conditions have to hold. The journey must be international. Your tickets must be separate contracts, which is the whole point, because that is the gap where European law does not reach. And you must have planned what the CIT calls a reasonable connecting time, meaning the time the official journey planners suggest, plus a few minutes to spare. Build yourself a nine-minute change that no timetable would recommend and you are on your own.

What you do at the station

Ask the staff of the delayed train, while you are still on it or as soon as you get off, for a Delay or Cancellation Confirmation. A conductor, a train manager, a station desk. Then take that confirmation, together with your original tickets, to the staff of the company whose later train you want to board.

There is no single European form. The CIT maintains an appendix of sample stamps and confirmations that runs to 34 pages, because every railway does it differently. German staff write the delay on the back of your ticket. Luxembourg has a stamp that says missed connection. That catalogue is the clearest possible explanation of why a member of staff in one country may not recognise a valid endorsement from another.

Who is in, and who is not

The signatories, as listed by the CIT in July 2025, include most of the names you would expect: SNCF, DB, ÖBB, SBB, Trenitalia, Renfe, Eurostar, NS, SNCB, DSB, SJ, ČD, PKP Intercity, ZSSK, MÁV, CFL and others.

The ones missing are the interesting part. Italo in Italy, Iryo in Spain, WESTbahn in Austria, Flixtrain, RegioJet. The cheaper operators, the newer ones, often the more direct ones. Transport and Environment, in a June 2026 report, gives the trap in one example: Paris to Vienna routed via SNCF, DB and ÖBB is covered by the agreement, while the more direct option through WESTbahn leaves you, in their words, with "no rights protection". The faster booking quietly costs you the safety net, and nothing in the booking flow tells you so.

Why you have never heard of it

Because the numbers say almost no one has. That same report, based on a questionnaire run with the French consumer group Que Choisir, found that 88% of respondents did not know the Agreement on Journey Continuation existed. Only 7% had heard of HOTNAT, a separate and older scheme run by the Railteam alliance that does something similar on high-speed routes. And the report makes the point that matters most: the agreement "is not automated: if station or onboard staff are also unaware of it, passengers are far less likely to receive a replacement ticket". Of the travellers surveyed who missed a connection between two operators, twelve should have been covered and were not.

The European Commission has now said the same thing in a legislative text. Its May 2026 proposal on passengers with single tickets describes the existing voluntary agreements as "non-binding, of limited scope and unknown to passengers, leading to inconsistencies in their application". The same document notes that the large incumbent railways, asked whether they wanted binding rules, preferred to keep the voluntary ones. The proposal would replace goodwill with an enforceable right for anything bought in a single transaction. It is a proposal, not law, and it has Parliament and Council ahead of it.

Where the law already protects you

Separately from all of this, Regulation (EU) 2021/782 has applied since June 2023, and it is a real right rather than a goodwill gesture. It only covers a through-ticket, meaning a single transport contract. If your delay at the final destination reaches 60 minutes, the operator must immediately offer you a refund or re-routing at the earliest opportunity, at no extra cost. Compensation is 25% of the ticket price for a delay of 60 to 119 minutes, and 50% from 120 minutes. Above 60 minutes you are also owed meals and, where an overnight stay becomes necessary, a hotel.

Two details in that regulation are worth carrying with you. Article 12 says the seller must tell you, before you buy, whether your tickets form a through-ticket. And tickets bought in a single transaction from a railway undertaking count as a through-ticket, with full liability attached, unless the seller states on the ticket that these are separate contracts and told you so beforehand. So read that line at checkout. It is the line that decides whether you are protected by law or reliant on the goodwill of whoever is on shift.

The slow way around all of this

Every rule above exists because of tight connections. The agreement asks you to leave a reasonable gap. The law starts counting at sixty minutes. The trap is always the itinerary that looked efficient on a screen.

Leave the long gap. Take the earlier train, and spend the hour in the station café instead of on the platform doing arithmetic. A journey planned with room in it is not just a calmer journey, it is a journey where none of this can be used against you. And if the worst happens anyway, ask for the delay confirmation, say the name of the agreement out loud, and be ready to explain it politely to someone who has never heard of it either.
