I am looking for a short story that appeared a number of years ago likely in either a November or December issue of Trains.  It is a story about a hospital nurse in Boston who has a patient that reports about a childhood memory of a locomotive engineer who threw oranges out his steam engine cab for kids living next to the tracks to pick up when looking for coal lumps to take back to their homes.  This would happen only at Christmas time.  I have no author or title but remember the story as it made quite an impression on me.  Can anyone recall which Trains issue contained this story?   Thanks very much.
