"I can't understand it. Peter Sam seems to just stroll along the line. He makes work look so easy!"
— Sir Handel, Special Funnel, fourth season

Peter Sam
  • Number: 4
  • Builder: Kerr Stuart, Stoke-on-Trent
  • Designer: James Kerr & John Stuart
  • Built: 1920
  • Configuration: 0-4-2ST

Peter Sam, named after the Skarloey Railway's previous controller, Mr. Peter Sam - previously Stuart, after his designer, Kerr Stuart - is a narrow-gauge tank engine who lives and works on the Skarloey Railway.

Bio in the Railway Series

Stuart was built by Kerr Stuart Works in Stoke-on-Trent, England.

While living on the Mid Sodor Railway, he was cheeky and occasionally made fun of Duke until told what happened to Stanley.

After the line closed down in 1947, he and Falcon were sold to the Sodor Aluminum 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 1952.

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 was eventually knocked-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.

Bio in the Television Series

Peter Sam has always been a cheery little engine. In the sixth season, his whistle snapped right off when a tree branch had caught it.  He also helped the Refreshment Lady find a place to put her new tea shop. Peter Sam once had to deliver a new winch for the incline at night, but got lost trying to find the magic lamp from the legendary engine, Proteus. In result, Harold helped him find his way home by shining down his light.

Peter Sam was once put in charge of the Skarloey Railway while Mr. Percival was away, but ran out of coal. In result, Victor came and brought him coal, and fixed Skarloey, Sir Handel, and Duncan afterward. He is currently working on the Skarloey Railway, and at the Blue Mountain Quarry, with the other narrow gauge engines.


Peter Sam, named Stuart in his younger days while being brought up under the instruction of Duke, is highly enthusiastic, eager, and bubbly. He can be occasionally cheeky, teasing, and a little cocky, but is kind-hearted, well-meaning, and good mannered. He can also be prone to being a little naïve at times and perhaps take things a little too literally. Peter Sam has a special funnel which makes puffing much easier, after his old one was damaged in a nasty accident with some trucks that broke free from the incline. With an infectious attitude and high spirits, Peter Sam is almost kind and hard-working to a fault, seldom grumbling about late hours or extra work. He is always nice to the coaches and even the trucks.


Peter Sam is based on the Talyllyn Railway's Edward Thomas. Interestingly, Edward Thomas only donned the Giesl ejector funnel for a limited time, while Peter Sam has used his since its introduction.


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-and-yellow lining.

In the television series, Peter Sam has always been painted green with red and gold lining.

In The Thomas Way DVD, the Mr. Perkins segment features a re-illustrated version of Trucks!. In this, Peter Sam is painted dark green, like in the television series.

He went into the tunnel
lost his old funnel.
Now his famous new funnel's a drain!"
