Corey is a very sleepy engine. Some tease him and call him 'Snorey Corey'. Others care about him and call him Corey. At first he was very tired and nearly had a crash. Now he's not as tired because Sir Topham Hatt understands he's feeling overworked. In late 2009 he was overhauled. Corey is painted black. He is based on a Baldwin saddle tank 0-4-0.
