Trainline Code Checks, Day by Day

Every Trainline code check from the last 14 days, plotted by the day it ran. Green is how many came back working. Red is how many thetrainline.com would not accept. That is the checkout testing you did not have to sit through yourself.

where this data came from:
1,493 automated cart runs149 shoppers reporting back18 tracked orders

149 of these results came from shoppers telling us whether a code worked; the rest come from automated checks and the other sources above. Last confirmed working on . Codes that stop clearing get pulled off this page automatically.

What These Numbers Mean

A code check is one result for one code. Most are our agents applying it to a real cart and reading the order total before and after; the rest come from tracked orders and from shoppers reporting back, as broken down above. Worked means the code was accepted and the total went down. Would not apply means thetrainline.com refused it on that cart. That is not the same as the code being fake. The usual reasons are:

  • It expired or the store switched it off after it was published.
  • It was single-use and had already been redeemed.
  • It only covers certain categories, brands or individual products.
  • The cart did not reach a minimum spend.
  • It is limited to new customers, a first order, or an email sign-up.
  • It cannot be combined with an active sale or another code.
  • It is tied to a different country, currency or membership.

So a code that failed one check can still work on your cart, and the success rate (checks that worked divided by all checks) is best read as how easily Trainline discounts apply in general, not as a verdict on any single code. Hover any bar in the chart to see that day on its own.

Before You Buy at Trainline

What shoppers ask most about Trainline.

›Can I use multiple promo codes on a single train ticket booking?

Promo codes cannot be combined with any other Trainline offers and are strictly limited to one redemption per transaction. Each code is also tied to specific currency selections like USD or GBP depending on the campaign rules.

›Do discount codes apply to booking fees and all rail operators?

Promo code discounts apply solely to the base ticket fare and never cover service booking fees or administrative charges. Certain promotional fares or specific international rail operators may also completely exclude code usage.

›Are promotional codes valid for travel outside of the UK and Europe?

Trainline promotional codes are restricted exclusively to train journeys operating within the United Kingdom and European Union networks. Tickets booked for international rail passes outside these regions are ineligible for code redemption.

›How do I cancel or modify a ticket purchased through the app?

You can request cancellations or date changes directly through the My Bookings section in the Trainline app. Availability and any processing fees depend entirely on the fare rules dictated by the underlying train operating company.

How We Verify Trainline Codes

Nothing goes up here on trust. A Trainline code is collected, applied to a real thetrainline.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.

The agents keep retesting every Trainline code on this page. No one here vouches for a code they did not watch work. If one slips through expired, take the next on the list. We keep backups. Want more codes we have watched work? See top-rated verified promo codes from every store.

Help Other Trainline Shoppers

Not every Trainline code reaches us from the store. 6 codes on this page were first submitted by shoppers. They have also sent back 149 checkout results in the last 14 days, telling us which codes worked on a real cart and which came up empty. Wherever a code comes from, it still has to pass the same cart test before it goes up here.

Have a code we missed?

Send it over and the agents will run it through a real thetrainline.com cart. If it works, it lands here with the test behind it.

Did a code work for you?

Open any Trainline code above and tell us whether it worked. It takes one tap, no sign-up, and a code that keeps failing gets pulled off the page.
