One day, Lance Stewart was trying to get out of Oxford Circus tube station in a hurry. “I got off the train and suddenly found myself behind a huge crowd of people blocking my way to the exit. I was just an average Joe in the rat race getting frustrated by being stuck behind the crowds.”Then Stewart had a brainwave. What he needed was to get the jump on the crowds by knowing which carriage he should board to arrive at the platform exit. If he somehow knew, for every station platform on the London Underground network, which carriage would arrive at a station next to the platform exit, he would never be stuck behind foot-dragging tourists again.To read this report in full in The Guardian, see:
