I think a lot of people in the UK would agree with this. It's not perfect but the rail system on the whole is pretty great for getting around the country. There's some annoying things like having to go to a hub to go back the way you came sometimes. But without a sprawling expensive network that's somewhat unavoidable. And obviously some lines are worse than others re delays and cancellations.

Most complaints in the UK are about cost of tickets. They are very valid complaints imo, the cost of getting a train in this country can be absurd. There would be a really positive attitude towards train travel in the UK and our rail system if it wasn't trying to bankrupt you every time you use it.
