— Mr. Percival, Duncan's Bluff, tenth season

Mr. Peregrine Percival, "the Thin Controller"

Mr. Peregrine Percival, also called the "Thin Controller" ("Narrow-Gauge Controller" in the US), is the current manager of the Skarloey and Culdee Fell Railways in the television series. In the magazines, he also runs a Cable Railway.


Mr. Percival was hired sometime between of the seventh and ninth seasons to help Sir Topham Hatt manage the ever-increasing size of the railway industry on the Island of Sodor.

Mr. Percival has had five children with his wife.

He was one of the important visitors who attended Dowager Hatt's special tour of Sodor and then a party at Knapford. He later charged Peter Sam with the running of the Skarloey Railway whilst he attended a meeting with Sir Topham Hatt, and welcomed Luke to his Railway.

In the eighteenth season he scolded Duncan for his grumpy disposition. He and Victor later made a bet challenging him to change his behaviour, offering him a new coat of paint as a reward.
