The Norbridge Stationmaster was the supervisor to Colin Stiles when he was a porter back in 1944. He was also in charge of Norbridge Station at that time.
Colin's stationmaster came out of his office, feeling concerned about Mary's troop train that was supposed to be due through Norbridge station. Colin told him that it will be coming after the stationmaster said it was very odd that the train should be at the station right now. Later, when the ammo train caught fire and Colin told Winston to stop the train, the stationmaster told the porter what was he doing. When the porter told him that Winston's train was on fire, the stationmaster replied that the train was full of munitions, just before turning to evacuate the passengers inside the station building to get outside quickly before an explosion could occur at any moment in time.
