Absolutely this. The Major Incident plan seems to have worked like a well oiled machine, all the Emergency Services were calm, professional and efficient. And if anyone says otherwise, chuck *them* however many kilos of safety gear and medical equipment, tell them people they know might be dying, and have them scramble to a location through London rush hour, assess a situation, and get the gear on and down to the middle of a tunnel underground. See how long it takes.
