"What can I use a trainline discount code on?"

"Trainline discount codes are typically tied to specific ticket types, routes, or operators — they won't necessarily cover every journey. The OUIGOSUR code, for example, applies exclusively to South of Spain OUIGO services. Most codes exclude season tickets and coach travel. Always check the terms listed alongside each offer on this page before building your booking around a code. If your route isn't covered, automatic savings like advance fares, SplitSave, and Railcards usually deliver a comparable or better discount without needing a code at all."

"Can I use more than one discount code on a single trainline booking?"

"No — trainline allows only one promo code per booking, and it cannot be combined with another promotional code. A Railcard discount, however, isn't a promo code; it's a permanent benefit tied to your account and applies automatically alongside SplitSave, GroupSave, and advance pricing. So while two codes can't be stacked, the combination of a registered Railcard and SplitSave on the same booking is perfectly valid and routinely produces the lowest available fare."

"Can students get a discount at trainline?"

"Students and graduates can purchase a 16-25 Railcard at a 15% discount through trainline, which then saves roughly a third on most rail fares. Verification is handled through the trainline website or app — you'll need a valid student ID or institutional affiliation to qualify. The discounted rate applies to the Railcard purchase itself; once activated, the standard third-off savings apply to every eligible journey you book through the platform."

"What is SplitSave and how does it work?"

"SplitSave is a trainline feature that automatically identifies cases where buying separate tickets for segments of the same journey costs less than one through ticket. You stay on the same train for the entire trip — nothing changes except that you carry multiple tickets instead of one. Savings of up to £13 are available on eligible routes. The feature runs automatically when you search; if a cheaper split exists, trainline displays it alongside the standard fare so you can compare."

"Where do I enter a promo code on the trainline app?"

"In the trainline app, search for your journey and proceed to the payment page. Scroll down to find the box labelled \"Add a discount code\" — paste your code exactly as shown on this page and tap apply. The discount should appear in the total before you confirm payment. On desktop, the field appears in the same position at checkout. If the field doesn't appear at all, your selected ticket type may not be eligible for promotional codes."

"Can I get a refund or change my trainline ticket?"

"Refund and change rules depend on the ticket type. Advance Single tickets can usually be changed for an admin fee but are generally non-refundable. Off-peak and anytime tickets are typically refundable, though a small fee may apply. If your train is cancelled, you're entitled to a full refund regardless of ticket type and no fee is charged. Access these options through \"My Tickets\" in the app, or via the refund section at the bottom of trainline's homepage."

"Does trainline offer a new customer discount?"

"Trainline doesn't run a standard new-customer welcome discount. First-time savings tend to come through Railcards, SplitSave, or booking advance fares early rather than a sign-up code. That said, creating a trainline account is free and gives you access to ticket alerts, price tracking, and any email-exclusive offers that do appear from time to time. Signing up costs nothing and takes only a minute, so it's worth doing even without an immediate discount."

"Is there a trainline refer-a-friend scheme?"

"Trainline doesn't currently operate a refer-a-friend programme, so neither party receives a referral bonus for sharing the platform with friends or family. You can still share deals and offer links from this page, though. The most reliable ongoing savings come through Railcards — a third off most fares — and booking advance tickets as early as possible, typically around 12 weeks before travel when the cheapest fare tiers are first released."

"Why isn't my trainline discount code working?"

"There are several common reasons a code might not apply:\n\n1. The code targets a specific route or operator that doesn't match your booking — OUIGOSUR, for example, is limited to South of Spain OUIGO services.\n2. Your booking includes coach travel, which most trainline codes exclude.\n3. You've already entered a different code on the same booking — only one promo code is allowed per transaction.\n4. The code has expired or reached its usage cap.\n5. The minimum spend or ticket-type requirement hasn't been met — some codes only work on advance or off-peak fares.\n"

About the Brand

Trainline is Europe’s leading digital platform for train and coach booking, founded in 1997 and headquartered in London. The company listed on the London Stock Exchange in 2022 and now connects travellers with over 270 rail and coach operators across 45 countries. Its app has been downloaded more than 30 million times, making it one of the most widely used travel tools on the continent.

The platform sells advance, off-peak, and anytime tickets for UK rail journeys, alongside Eurostar and continental services into Spain, France, the Netherlands, and beyond. Digital railcards — 16-25, Senior, Two Together, Family & Friends, and others — can be purchased directly through the app, each saving roughly a third off standard fares. Season tickets and Flexi Season tickets round out the options for regular commuters.

Several built-in features deliver savings without any promo code at all. SplitSave automatically breaks a journey into cheaper segment tickets while you stay on the same train, with savings of up to £13 on eligible routes. GroupSave applies a third off when three to nine adults travel together on qualifying services. The app sends real-time platform changes and delay alerts, and advance fares for popular routes — London to Manchester, for instance — can start from under £15 when booked well ahead.

Between railcard discounts, SplitSave, and the occasional promo code for specific operators or routes, there are usually several ways to bring a journey’s cost down. The offers gathered on this page are a solid starting point.

How to use

Most trainline savings listed here apply automatically — no code required. For the occasional code-based offer, such as OUIGOSUR for Spanish OUIGO routes, click the offer card on this page to copy the code to your clipboard. Then open thetrainline.com, search for your journey, and proceed to checkout. On the payment page, scroll to the “Add a discount code” box, paste the code exactly as shown, and click apply. Confirm the discount appears in the total before completing payment.

Automatic Deals and Fare Savings

The majority of trainline’s offers are automatic — railcard discounts, SplitSave savings, advance fare reductions, GroupSave, and family travelcards all kick in without a promo code. Browse thetrainline.com or the app, search your route, and the platform displays the cheapest available fares. Look for the SplitSave badge on eligible journeys, and consider downloading the app for exclusive mobile-only deals and real-time journey alerts.

Railcard Discounts for Students and Seniors

Students and young travellers can purchase a 16-25 Railcard at a 15% discount through trainline, which then saves roughly a third on most fares. Senior travellers have a similar route with the Senior Railcard — three-year orders currently save £25 compared to buying annually. Verify your eligibility through the trainline website or app with a valid form of ID or institutional affiliation before purchasing.

If a code doesn’t apply or a deal doesn’t match what’s shown on this page, click the report button on the relevant offer card. We review flagged listings daily and will update or replace any that aren’t working as expected.

Shopping Guide

When is the cheapest time to book train tickets through trainline?

Advance tickets are released roughly 12 weeks before travel, and the cheapest fare tiers tend to sell out within days of appearing. January is historically the strongest month for rail discounts — trainline and its operator partners have previously offered up to 50% off advance and off-peak fares during New Year sales. Outside of January, booking as far ahead as possible and travelling at off-peak times (mid-morning, mid-afternoon, or after 7pm on weekdays) will nearly always beat buying on the day.

Is it worth buying a Railcard through trainline?

If you take more than a handful of train journeys a year, a Railcard pays for itself quickly. A 16-25 Railcard costs around £30 for one year but saves a third on most fares — a single London-to-Manchester return can recover a significant chunk of that cost. Buying a three-year railcard through trainline currently saves £25 compared to purchasing year-by-year, so anyone who qualifies for the full three years should go for the longer option.

How does SplitSave actually work, and can I trust it?

SplitSave identifies cases where buying separate tickets for parts of the same journey costs less than one through ticket. You stay on the same train for the entire trip — nothing changes about your journey. Savings of up to £13 are available on eligible routes, and in our testing the feature consistently found cheaper fares on cross-country journeys. The only practical difference is carrying multiple tickets, which the app handles seamlessly.

Can I combine a Railcard with SplitSave for bigger savings?

Yes — a Railcard discount isn’t a promo code, so it works perfectly alongside SplitSave. The two-stack combination routinely delivers the lowest available fares without any promotional code at all. What you can’t do is apply two separate promo codes to the same booking. Our advice: register your Railcard on the app first, search your route, and let SplitSave find the cheapest ticket split. The savings compound quickly on longer journeys.
