They didn't have a good afternoon. I was on the 15.55 that broke down. We had to alight at Hayes and the next HEX service stopped for us. I was extremely appreciative but you can imagine those on the 16.10 weren't as excited when 200 extra people boarded. Weird argument and then public apology on the PA by one of the staff after a shouting match with a member of the public.
Eventually train arrived about 23 minutes late, so 38 mins late for the 15.55. could have been a lot worse but plenty of people running as we arrived at T5
