Thomas is the first book in the My Thomas Story Library series.
Thomas is a tank engine who enjoys teasing the bigger engines. One day, Gordon takes revenge on Thomas and pulls him along behind the train at high speeds. Thomas is careful never to be cheeky to him again. The next day, he saves James after trucks push him off the line. The Fat Controller is pleased with Thomas and gives him a branch line all to himself.
