The Small Controller

Mr. Fergus Duncan, also known as the Small Controller, is the controller of the Arlesdale Railway. He is taller than Sir Topham Hatt and Mr. Percival; his nickname refers to the fact that his railway is often called the "Small Railway".


He was appointed by the Fat Controller, the Thin Controller and The Owner to run the line so they could get the supplies of ballast that reside in the hills on his line.

He, Reverend W. Awdry, and Reverend T. Boston later went on a search for Duke.

After Rex's steampipe began leaking one day and Frank had to take his train, the Small Controller began thinking they needed another engine and so he arranged for Jock to be built.
