midnight
They began to know the hours when certain trains passed , and they gave names to them . The 9.15 up was called the Green Dragon . The 10.7 down was the Worm of Wantley . The midnight town express , whose shrieking rush they sometimes woke from their dreams to hear , was the Fearsome Fly-by-night . Peter got up once , in chill starshine , and , peeping at it through his curtains , named it on the spot . It was by the Green Dragon that the old gentleman travelled . He was a very nice-looking old gentleman , and he looked as if he were nice , too , which is not at all the same thing .
