I have told this before, but five or so years ago I was waiting in a train at Pier Head and, when the guard shut the doors, one of the leaves stopped half-way over to have a rest. All quite normal. A couple, probably visitors, were sitting opposite and the woman said,” Is there a problem with the doors? Should we tell someone?” I replied, “ No, that’s quite normal. The doors are often like that, but the trains are seventy-five years old and you’d take your time at that age.” “Seventy-five! Are they safe?”
