Tube ponderings with Barry Heck
Our resident tube fancier dishes out daily thoughts on the London Underground.
Tube know-it-all Geoff Marshall has just walked into the office as I'm writing this. "Geoff, Geoff, give me a tube fact," I say. "Easy," he replies. "The longest tube station name, including punctuation, is King's Cross St Pancras at 23 characters." And that's why we love him.
