Condition 30 of the National Rail Conditions of Carriage provides for a full refund of a ticket if your train is delayed or cancelled and you decide not to travel. How is this calculated if this relates to the outward journey for a return ticket? If you have decided not to travel then the return journey is also likely not to occur. However, whilst there are specific provisions for most Delay Repay schemes which usually work on the basis of only a proportion of the ticket being refunded when the delay is for one half of the journey, the NRCoC says nothing about this for Condition 30 delays. What is the expected practice for such claims?
