I was on that train, pissed off was an understatement, I got to my seat in the WSU 15 mins into the first half, the train was due to leave at 13:12 from Brighton
I do wonder what you were doing. I was on the train that was due to leave at 13.12 (it left at twenty past) and got to my seat three minutes into the game, It was my first time going by train to the Amex, I was a bit worried as I didn't finish rugby training till 12.45 but I hardly missed any of the game - thought it worked pretty smoothly TBH.
