The majority of train companies use a system called Delay Repay. If your train is more than 30 minutes late, you will always be able to claim a quantity of your money back. One aspect to bear in mind is that not all companies use Delay Repay, so your train may need to be delayed longer than 30 minutes for you to be entitled to a refund.nnTypically, you’ll receive 50% of the cost of a single ticket or 50% of a relevant part of a return ticket if your train is 30 minutes late. In the worst-case scenario, if your train is cancelled, you’re entitled to a full refund regardless of what type of ticket you purchased.
