Spencer and the Herring Gull

Sir Ralph Wedgewood comes to Sodor and Spencer thinks he's an imposter. Who would Sir Ralph Wedgewood really be? Narrator: It was a sunny day on Sodor and the engines are busier like bees in a hive. One day, Gordon was resting in a siding when he heard a shrill whistle.
