Haven't really noticed the tubes getting worse (apart form the heat) yet, but from what I understand King's X will be like a warzone from tomorrow. Have to find another way home, or just not leave the house.
i got to heathrow yesterday with huge amounts of luggage and got it all back on the underground to stratford just after rush hour and it was easy. the tube is a bit hot and sweaty but thats true every summer. i know its fun to whinge but i think in this case its entirely unjustified.
