Trainline referral code UK: rail credit after you travel

Quick answer

Skip hunting for expired vouchers. Use the verified referral link instead.

Trainline referral credit usually needs a first qualifying ticket — not an empty app install. Fair Share shows the next member invite; confirm rail credit on the brand page before you send the link.

Ticket first, credit second

In-app Trainline invites typically credit both sides after a qualifying booking. Installing the app alone is not enough.

Reveal the next member Trainline invite on the brand page. Buy the ticket under Trainline’s invite rules, then watch rail credit apply per their timeline.
