I really enjoyed reading Train Travel in the UK: A Foreigners Perspective.
The part that stuck out to me is quoted below
This might surprise British readers, but I have nothing but good things to say about the reliability and punctuality of trains in the UK.
I travelled quite extensively throughout Europe by train in the last three months and of all countries visited it was the UK which had the best record when it came to trains running on time as I don’t think I had one which arrived more than five minutes late.
The above sentiment is similar to my own and not shared by many here in the U.K.
I believe trains are a superior mode of transport for most “mid-distance” travel and should replace a large amount of car journeys and some plane journeys. The main issue is cost. Most people can’t afford to take trains in the U.K. regularly, unlike in most of Europe.
