"No, Rheneas! We mustn't bother Victor with little things!"
— Peter Sam, Don't Bother Victor!, sixteenth season

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


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 afterwards. 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, a Kerr Stuart Tattoo 0-4-2ST. 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 dark 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 dark 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.
