A suburban local was stalled by a blizzard one winters night, and so deep was the snow that its passengers were unable to leave the car. Next morning the hundred and fifty-odd half-frozen commuters were startled to see a manned signal tower only a few hundred yards away. The signal-station attendant had seen the stalled train the night before, but when asked why hed done nothing about it, he answered, 'Its not in my territory.'
