I have just been wasting half an hour and following an item during the week on TV I decided to look at buying train tickets by splitting the journey. I used the National Rail Enquiries site and just accepted the default settings, so further filtering could affect the results. I looked at London to Norwich. The basic fare came out at £45 single, traveling today, Sunday. However, a single ticket between London and Colchester is £22, and a single between Colchester and Norwich is £16.50. Not an earth shattering saving, but a couple traveling could save enough to pay their taxi fare from Norwich station into the city centre. Buy online and print your own tickets and you don't even change trains. I am not sure how it works if you turn up at the booking office and request two tickets. Anyone any experience of such things?
