The Thin Controller

The Thin Controller is the term that the controller of the Skarloey Railway is often referred to as. In The Railway Series, the Thin Controllers were (in order) Mr. Mack, Mr. Robert Sam, Mr. Peter Sam and Mr. Roger Sam. In Thomas & Friends, the only Thin Controller is Mr. Peregrine Percival.

Did you know? Mr. Peter Sam's attire and physical appearance in the 1979 annual may have been the inspiration for Mr. Percival, as they both have the same hairstyle and wear the same clothing and bowler hat.
