Travelling by train with children can make a multi-city European trip easier, but the journey works best when you plan around the family’s needs—not only the timetable. The right seat arrangement, a manageable connection and a clear plan for delays can prevent small problems from becoming stressful ones.

Train rules vary by operator and route. Check the conditions for each service before booking, especially when your itinerary includes cross-border trains or separate tickets.

Do children need their own train tickets?

Children usually need to be included in the booking, even when they travel free or at a reduced fare. Age limits, child fares and seat rules vary by railway operator. Some services let young children share an adult’s seat; others require a separate ticket or reservation.

Before you book, check:

• The operator’s age limits for child fares
• Whether each child needs a separate ticket
• Whether a seat reservation is required or optional
• Whether children must travel with an adult
• Whether the operator requires proof of age

Enter each child’s age when searching for fares. A free or discounted child ticket may not include a separate seat.

When should you reserve seats?

Reserve seats when the train offers them and your family needs to sit together. This matters most on long-distance services, during school holidays and on popular routes where trains can fill up.

Some operators include reservations in the ticket price. Others charge separately, while some regional trains don’t offer reservations at all. On services with compulsory reservations, you need to book a seat before boarding.

When families book train tickets online, they should enter each child’s age and check whether seat reservations are included.

Check your booking confirmation for the number of seats, carriage and seat numbers, and any rules for changing the reservation. If the booking system separates your family, contact the operator before buying separate tickets.

Choosing seats that work for children

The best seating arrangement depends on the children’s ages and the journey length. Younger children may need to sit beside an adult. Older children may be comfortable across the aisle or at a nearby table.

If seat selection is available, consider:

• A table: useful for snacks, games and drawing on longer journeys
• Seats near luggage storage: convenient for bags, but keep valuables with you
• Seats close to the carriage door: helpful when getting off with children, though these areas may be busier
• A family compartment: available on some services, but not on every route

Check the seating plan before selecting seats. A table arrangement may place your family opposite another group, and layouts can differ between carriages.

Plan transfers around your family

A train transfer involves more than changing platforms. You may need to cross a station, check departure boards, use a lift or stairs, and move luggage while keeping children close.

Avoid choosing a connection based only on the shortest transfer time. A longer stop can be worth it at a large station, especially with a stroller or several bags.

Before booking, check:

1. Transfer time: Allow enough time for children to walk, use the restroom and manage their bags.
2. Station layout: Some stations require a walk through a concourse or a change of level.
3. Platform information: Platforms can change, so check the departure boards when you arrive.
4. Accessibility: Confirm step-free access if you use a stroller or need lifts.
5. Ticket conditions: Separate tickets may have different rules if the first train is delayed.

If the itinerary includes several changes, compare it with a direct service. The fastest itinerary on paper may not be the easiest one with children.

What if a train is delayed?

If your first train is delayed, check the operator’s instructions before leaving the platform. Your options depend on the ticket, route and reason for the delay. With separate tickets, the next operator may not automatically accept your original booking.

Keep tickets and booking confirmations accessible, and save the relevant operator’s app or customer-service details before departure. If you have a tight connection, ask station staff for help as soon as possible.

Make station changes easier

A little preparation helps children manage busy stations and unfamiliar signs.

• Show children the destination and train number on the ticket.
• Explain that platforms can change and check the departure board together.
• Keep tickets, passports and essential items in one accessible bag.
• Give each child a small backpack they can carry comfortably.
• Agree on a meeting point in case someone becomes separated.
• Keep snacks and water available, especially if the next train is delayed.

At stations with lifts, allow time to find them. If a lift is out of service, ask staff for an accessible route rather than attempting stairs with a loaded stroller.

Book early when the route requires it

Booking early can give families more choice of departure times and seats, particularly on popular high-speed and international services. Booking windows vary by operator, so check the release dates for your route rather than relying on one general rule.

The earliest you can book a train ticket varies by operator, so check each service’s booking window before planning around a specific departure.

Once tickets go on sale, compare the full journey – including seat reservations and transfer times – before choosing the lowest fare.

Family train trip booking checklist

Before paying, confirm that:

• Every traveller has the correct ticket and age category.
• Required seat reservations are included or added.
• Seats are together or arranged in a way that works for your children.
• Transfer times allow for walking, luggage and platform changes.
• You know if the itinerary uses one ticket or separate tickets.
• You have checked the operator’s rules for delays, missed connections and changes.
• Station accessibility meets your needs.
• You can easily access tickets and booking details during the trip.

FAQs 

Can children sit on an adult’s lap on European trains?

Some operators allow young children to travel without a separate seat, but age limits and ticket rules vary. Check the conditions for your specific train. For a longer journey, a separate reserved seat can make the trip more comfortable.

Do seat reservations guarantee that a family will sit together?

A reservation confirms the assigned seat, but the available seating options depend on the operator and train layout. Review the seat numbers before completing the booking and contact the operator if the family is split across the carriage.

How much time should we allow for a train transfer?

No single transfer time works for every station. Consider the station size, platform distance, luggage, stroller use and children’s pace. When possible, choose a connection that leaves enough time to move without rushing.

Is a direct train better when travelling with children?

A direct train removes the need to change platforms and manage a connection. It can be a practical choice with younger children, lots of luggage or a stroller. A connecting route may still work well if it offers a useful break and a comfortable transfer.

What happens if we miss a connection because the first train is late?

The next steps depend on your ticket and the operators involved. Check the conditions before travel, especially if you bought separate tickets. If there’s a delay, ask railway staff for help and keep your booking details handy.
