When Good Trains Go Bad

Am currently heading back up North on the East Coast Mainline 13 hours later than I should be. Signal problems brought the whole line to a grinding halt - much as I love trains, they can't just skirt around a problem. We sat at King's Cross for a hour with no indication of when we might get going so I bailed out and went out to dinner with some old friends - a silver lining to every cloud and all that!
