Connections, Minimum Connection Time and Through-Tickets

A connection links consecutive services. Minimum Connection Time (MCT) is the operational minimum allowed for the transfer. Whether the journey is sold as a through-ticket or as separate contracts is a different question, and can affect the help available after disruption.

A connection may involve a walk between platforms, a move between stations in the same city or a local-transport leg. The route through or across the station matters as much as the number of minutes in the itinerary.

What minimum connection time means

MCT is set for a particular station or station group and service context. It is the minimum time considered sufficient to move between the arrival and departure points for consecutive services. A cross-station transfer may have a different minimum from a change within one station, and extra time may be built in for passenger assistance, bicycles or check-in.

There is no single MCT for Europe. An MCT is also not a guarantee that you will catch the train, find a seat or qualify for compensation. Those outcomes depend on the actual journey, the tickets held and the rules that apply.

Allowing a realistic margin

The operational minimum is a planning floor, not necessarily a comfortable target. Extra time is useful when the station is unfamiliar, the route between platforms is long, you have luggage or a bicycle, you need assistance, or the itinerary includes a transfer across town. Even a carefully planned margin can disappear when the incoming train is late.

No single buffer suits every journey. A longer connection matters most when the onward train is infrequent, has a compulsory reservation or would be expensive to replace. Some journey planners, including DB Navigator, let you request a longer transfer time.

Through-ticket or separate tickets?

A through-ticket covers successive rail services as one contractual journey. Tickets sold together may instead be identified as separate transport contracts. This contractual distinction is separate from the number of trains involved, and it can affect who must help after a missed connection.

For journeys within the scope of Regulation (EU) 2021/782, passengers must be told before purchase whether connecting tickets form a through-ticket. Connecting tickets bought from a railway undertaking in one commercial transaction constitute a through-ticket under the Regulation. Different provisions apply when a vendor or tour operator combines tickets on its own initiative, or when the passenger is clearly told before purchase that the tickets are separate contracts. The seller, transaction and advance disclosure all matter; a single basket or payment screen is not conclusive in every case. The Regulation's service scope and national exemptions still apply.

Great Britain has its own rules. The National Rail Conditions of Travel allow more than one ticket to be used for a journey when all their conditions are met. The train generally has to call where one ticket ends and the next begins, subject to an area-based exception in the Conditions, and every ticket's route and service restrictions still apply. The right to combine tickets in Great Britain does not make them an EU-law through-ticket.

A through-ticket is not a through train

A direct train or through train describes how the service operates. A direct journey normally involves no planned change of train, while a through coach can be attached to different trains during its journey. A through-ticket describes the transport contract instead.

A through-ticket can therefore cover an itinerary with a change of train, while separate tickets can sometimes cover a journey on the same physical train. If the practical question is whether you must move, use the train numbers, coach information and itinerary instructions. The related glossary entry on through trains and through coaches explains the operational distinction.

Planning the connection

Start with the exact place of the change. A transfer within one station can still involve stairs, lifts, distant platforms or a long walk. A transfer between city stations adds a journey across town and should not be treated as an ordinary platform change.

Match the arriving and departing services by date, time, destination and train number. Build in time for the route through the station and any check-in or boarding process. Travelling with children, a bicycle, luggage or assistance usually calls for more than the shortest displayed connection.

Before paying, look for an explicit statement that the itinerary is a through-ticket or consists of separate contracts, and keep the tickets and seller details. If separate tickets are materially cheaper, balance the saving against the cost and difficulty of replacing the onward journey when no protection applies.

If you miss the connection

There is no automatic Europe-wide outcome. The ticket relationship, the operator's instructions and the passenger-rights rules for the journey determine what happens next. Rerouting, refunds and compensation are separate questions: entitlement to one does not automatically establish the others.

In Great Britain, the National Rail Conditions contain a specific rule for a ticket valid only on named services when an earlier connecting train is delayed or cancelled. Subject to the Conditions, the passenger may use the next service provided by the operator or operators for which that ticket is valid without penalty. This is a conditional Great Britain rule, not permission to board any train or a Europe-wide compensation promise.

Some international journeys on separate tickets may qualify for the Agreement on Journey Continuation (AJC) or another operator arrangement. AJC only applies to participating railway undertakings and journeys that meet its ticket, presentation and timing conditions. It is a defined fallback, not evidence that separate tickets carry the same rights as a through-ticket.

In brief

A connection is the planned link between services; the transfer is the act of moving between them. MCT is the operational minimum for a particular station and service context. A through-ticket describes the contract across successive services, not whether the journey is direct. Plan a realistic transfer margin and establish the ticket relationship before relying on missed-connection help.
