The announcement said "limited capacity" after 10:30, so basically, they couldn't guarantee you get home.
Really poor for a game they knew could go to extra time. This is NOT whinging - I had a seven year old daughter with me, I couldn't take the chance of not getting on one of the trains. I hate leaving early, but had to.
Judging at the train times posted.. from 22.05 to 23.47 you have enough trains/carriages to carry 6500 passengers from my calculations...
