How do I claim compensation for late trains?
National Rail - which oversees all train lines - says customers are able to claim compensation if their train arrive more than an hour late.
Emma Coulthurst from TravelSupermarket.com , said: "Grand Central, Great Western Railway and South West Trains are the only companies that stick to this 60-minute rule.
"If you are travelling with any other train company, such as Virgin or Great Northern, you can claim compensation if you are delayed over 30 minutes.
"To claim, you need to submit a form online or in the post. Most firms do this through a Delay Repay compensation scheme . Keep hold of all your receipts and make a note of the time you arrived at your destination.
"If you don't have it any more - as most likely it was gobbled by a machine at a ticket barrier - you should be able to use your receipt or credit card statement."
You can apply online or by post within 28 days of your delay. To do so, you will need proof of travel.
