Peter Sam, named after the Skarloey Railway's previous controller, Mr. Peter Sam - previously Stuart, after his maker, Kerr Stuart - is a narrow-gauge tank engine who lives on the Skarloey Railway. He speaks with a Welsh accent.
After the line closed down in 1947, he and Falcon were sold to the Sodor Aluminium Company at Peel Godred and worked there until 1951, at which time both engines were sheeted for a year until they were purchased by the Skarloey Railway in 1951.
Upon arriving, Stuart - renamed Peter Sam - had many adventures. One of his more notable story arcs involved his funnel, which was severely damaged after an accident at the incline. The funnel eventually fell off as he passed under a tunnel, and it was temporarily replaced with a rusty pipe. Peter Sam was soon given a new funnel, a Giesl ejector, which suits him much better.
Peter Sam is kind, well-mannered and popular with passengers and coaches alike. Even the trucks do not play tricks on him.
He is portrayed similarly, occasionally making mistakes by feeling self-important.
In the Railway Series, Peter Sam was painted green while working on the Mid Sodor Railway. After arriving on the Skarloey Railway, he was repainted in the Skarloey Railway's red livery with blue lining and his name painted in gold on his boiler.
In the television series, Peter Sam has always been painted green with red lining. He carried a gold nameplate while working on the Mid Sodor Railway. After arriving on the Skarloey Railway, he was given a red nameplate with gold writing.
