I agree with Freya. Trains are quite simply the greatest form of public transportation ever. I love my three-and-a-half hour train journey to Glasgow whenever I visit my best mate. Not that I'm a posh knob, but I always pay extra for a first class ticket. It's only an extra £8 if you book in advance and it's well worth it.

Sat in a comfy seat with a few beers, Game of Thrones to read, PSP to play Final Fantasy and a nice lady bringing me biscuits... perfection.
