Henry and the Tunnel is a My First Thomas-style book.
Henry is shut in a tunnel for being naughty since he did not want the rain to spoil his paint and is eager to get out. He is given the chance when Gordon breaks down while pulling the Express and the train is too heavy for Edward to move alone. Sir Topham Hatt lets Henry out of the tunnel so that he and Edward can pull the train together. As a reward for his hard work, Henry gets a new coat of paint.
- This book is based on the first season episodes, The Sad Story of Henry and Edward, Gordon and Henry.
- When Henry is coming out of the tunnel, he has no siderods.
