When my UK train is cancelled, I can travel on a later service. When travel disruptions are severe, I may instead choose to have my ticket endorsed by station staff for travel the following day, when this is preferable.
If I choose to travel the following day due to severe disruptions (many cancelled trains, others 1–2 hours delayed, probably leading me to miss my last train home and have to take another taxi, etc.), what is the nature of compensation am I entitled to?
Rule 42 of the Conditions of Carriage states that I am entitled to a 50% refund on a single ticket if my train is more than 60 minutes delayed, but does not explicitly cover the situation where I voluntarily agree to change my date of travel due to severe disruptions.
Had I tried to travel today, I would most likely have missed my last connecting train home and travel home by taxi, arriving several hours late.
Edit: The train is operated by Virgin Trains West Coast but was booked through Great Western Railways.
