50% off train tickets for children aged 5-15

Kids aged 5-15 benefit from a 50% discount on the price of a full adult ticket.

Children aged 5 to 15 inclusive get half-price fares for most tickets across the UK rail network. If your child is 4 or under, they can travel for free alongside a fare-paying parent or guardian.

If it’s a service with seat reservations, a child with a discounted ticket is eligible to reserve a ticket, just like any ticket holder. Kids aged under 5 can only occupy a seat if it is not required by a fee-paying passenger. If all spaces are occupied, they’ll have to sit on your lap.

The 50% discount for children applies equally to single and return tickets. For children who look 16 or older, it’s wise to bring along a form of ID to avoid any embarrassing conversations with the ticket inspector – they may want to verify that the child is eligible for discounted travel.

How to book child train tickets

Buying child tickets on Trainline is super-simple.

We’ve made it really easy to add children to your booking, or book stand-alone child tickets. Here’s how you do it:

  1. Use the Journey Planner at the top of the page to enter your origin and destination.
  2. Click on the passenger picker, just above the Search button.
  3. Add the child to your booking and click ‘Done’.
  4. Hit the Search button to see all the available times and tickets for your chosen route.

Fixed-price fares for families

As well as discounted child tickets, some train companies offer heavily discounted fares for families. Read on for more details or check out our dedicated page to family train tickets. These can often work out cheaper than buying separate child and adult tickets, and the prices are fixed, meaning they’re the same on the day as a month in advance. We will automatically display these fares where available, so you won't have to go searching for them!

£1 and £2 train tickets for kids

Several train companies offer £1 (or Kids for a Quid) fares and £2 tickets for kids when travelling with an adult on an Off-Peak service – brilliant value! Have a look at our curated list of £1 and £2 kids ticket offers.

Tips for travelling with toddlers

Bringing prams on the train

Buggies and prams are welcome on board trains in the UK. While there aren’t dedicated storage space for buggies, you can fold them up and place them in the overhead luggage storage. Train company staff will be on hand on the platform to help you load your buggy on to the train. Some train companies allow buggies to be stored in empty wheelchair spaces, but wheelchair users will always take priority. Be sure to check with staff on the train that you’re allowed to do so on your service.

Baby changing facilities on board

Most train toilets have baby-changing facilities, as do train stations. Newer trains, such as LNER’s Azuma fleet, have nappy changing facilities in all the toilets, whereas older trains may have one or two toilets with appropriate facilities.

You can check in advance whether a station has baby changing facilities on our Stations information pages.

What ages qualify for child train tickets?

Children between 5 and 15 inclusive are eligible for child fares, which offer a 50% discount on full-price tickets. Children aged 4 or under travel for free with an accompanying adult.

Are there Railcards for children?

Railcards for young people begin at the 16-17 Saver Railcard, which offers 50% off train travel for a year. Children aged 15 and below already benefit from heavily discounted tickets, so unfortunately, they aren’t eligible for Railcards yet!

Do families travelling together get discounted tickets?

Yes, certain train companies – such as LNER and Avanti West Coast – offer discounted fixed-price family fares for adults travelling with kids.
