Trainline Discount Codes

Trainline is a train and coach booking service where you can compare departure times, routes and fares through its website or app. Its Ireland store sells domestic Irish rail and coach tickets, alongside options for travel abroad. It also sells Interrail passes for journeys across Europe.

You can use it to compare individual journeys or plan the rail and coach legs of a longer trip. Check the operator and ticket conditions alongside the price: the lowest fare may have different change and refund rules from another ticket on the same route.

Savings depend on where and when you travel. Booking ahead may bring lower fares, while group, family, weekend and operator promotions can apply to selected journeys. Railcard and partner offers also feature, but eligibility depends on the country, operator and ticket. An offer for a British rail route should not be treated as a discount on an Irish booking.

Before using a Trainline discount code, read its redemption instructions and check that your journey qualifies. Follow the offer's booking steps and make sure the saving appears in the total before you pay. A railcard or loyalty card discount is different from a promotional code, so follow the instructions for the particular offer.

• Compare advance fares: Booking ahead may cost less, depending on the operator and journey. Compare the fare conditions as well as the price.
• Look for group or family fares: Selected operators offer savings for people travelling together. Check that everyone in your booking meets the conditions.
• Check weekend offers: Some promotions apply to weekend journeys rather than all departure dates. Match the offer to your travel plans before choosing a fare.
• Use an eligible railcard: Railcard savings depend on the network and ticket. Check where the card is valid rather than assuming it applies to domestic Irish travel.
• Compare pass and ticket costs: For a European rail trip, compare the Interrail options sold by Trainline with the individual tickets for your planned journeys.

Digital ticket bookings do not need postal delivery. Check the ticket format and any instructions attached to your booking before travelling, rather than expecting a paper ticket to arrive at your address.

Review the payment options offered for your booking before completing payment. The total and fare conditions matter as much as the headline ticket price, particularly if you may need to change your plans.

Changes and refunds depend on the ticket and transport operator. Read the conditions before paying, then use the relevant changes, cancellations or refund guidance for your booking if your plans change. Do not assume that a refund deadline or rule for a British ticket also applies to an Irish or European journey.

For another way to compare train and coach journeys, browse the offers on our Omio page. You can also check our travel discounts when planning the rest of your trip. For European train tickets and rail passes, compare Rail Europe, which also offers sail and rail packages for Ireland but does not sell domestic Irish train tickets.

How do I use a Trainline discount code?

Check the offer's redemption instructions and follow them before paying. Make sure your journey, ticket and booking method meet the conditions, and check that the saving appears before completing your purchase.

Why might a discount code not apply to my booking?

An offer may be restricted to particular operators, routes or booking methods. Check its validity and eligibility conditions rather than assuming a promotion for another country covers an Irish journey.

Will my tickets need to be posted to Ireland?

Digital ticket bookings do not require postal delivery. Check the ticket format for your selected journey before paying.

Can I change my ticket or get a refund?

Change and refund eligibility depends on your ticket and the transport operator. Read the fare conditions before booking, especially if your plans may change.

How else can I save at Trainline?

Compare fares in advance and look for group, family, weekend or operator-specific offers that cover your journey. If you hold a railcard, check whether it applies to the route and ticket you choose.
