Southeastern First Class.
 

I go to Canterbury quite a lot, I upgraded to first class yesterday as the train was dead busy, what I could not believe was that on a 375 first class is identicle to standard except paper things on headrests, feel I was robbed, on every other train I have ever used the first class has been better than second.

It's true. Same seats, a nice antimacassar if you're lucky, maybe different colour moquette. Tends to be a tad quieter though, as it's at the end of the train so nobody passes through. No freebies though!
