“Those trucks will pay you back! Trucks don't like to be biffed!”
Rusty to Duncan[src]

Slate Trucks are the Skarloey Railway's most common type of truck, and can be seen as the narrow gauge counterparts to the Troublesome Trucks. Besides transporting slate, they have been known to transport broken branches, hay bales, cows, and sheep. They dislike Sir Handel because he often bumps them. On the other hand, Peter Sam never bumps the trucks unless they misbehave.


The Railway Series

Once, the slate trucks mistook Peter Sam for Sir Handel, and decided to play a trick on him. At the slate mine, they snapped the chain attached to the winch on the incline and ran into him, cracking his funnel and denting his boiler.

In the fifth series, some empty slate trucks jammed the winch on the incline and ran down the slope into the ravine, causing an avalanche which buried Skarloey. Another time, they broke away from Peter Sam, and plummeted into the ravine at the old iron bridge.

In the sixth series, Rusty warned Duncan to be careful with the trucks after bumping them. Unfortunately for Duncan, he got his comeuppance when he jammed the incline winch and crashed into a muddy swamp with the slate trucks.

In more recent series, the slate trucks do not have faces. From Blue Mountain Mystery onwards, many faceless slate trucks are seen scattered around the Blue Mountain Quarry.

Technical Details


The white slate trucks are based on the 2-bar wooden slate wagons of the Talyllyn Railway. The third style of slate trucks are based on the ornate wooden bodied wagons from the Dinorwic Quarry on the 4 ft Padarn Railway. The fourth style of slate trucks are based on the Great Western '2 foot' gauge slate wagon, used on various narrow gauge lines such as the Corris, the Welshpool and Llanfair and the Vale of Rheidol Railways. The Slate wagons are based on a metal bodied wagon featured at the Narrow Gauge Railway Museum.
