This article contains plot details about an upcoming episode.
Stephen, nicknamed "The Rocket", is a steam engine who will first appear in the 2013 special, King of the Railway.
Stephen is one of the earliest engines ever built. Newer engines may be faster and stronger than Stephen, but what he lacks in terms of strength or speed, he makes up for with his positive spirit, sense of humour, and knowledge. He will have his own coaches and be trapped in a mine at some point.
Stephen is based on the Stephenson's Rocket.
Stephen is painted yellow and black. He bears a nameplate reading "Rocket".
He will appear in the seventeenth season.
