Trucks (called cars in the US narrations), are also commonly referred to as Troublesome Trucks because some of them can be quite troublesome to the narrow gauge engines. They resemble the coal trucks used by the North Western Railway. They are used for carrying coal, stone, flour, tools and other materials. They take a disliking towards Sir Handel, like the slate trucks and love to play tricks on an engine.
The trucks are based on several different narrow-gauge trucks on the Talyllyn Railway. The Bachmann narrow gauge trucks were based on the Lynton and Barnstaple Railway's 4-wheel goods wagons. In the magazines, the trucks are often incorrectly depicted as Standard gauge trucks.
- Three large scale trucks (One type 3, one type 2 and one type 1) are currently on display at the Hara Model Railway Museum. Four small scale type 2 trucks and two small scale type 1 trucks with their faces are currently owned by Twitter user ThomasTankMerch.

The "Weedkiller" is a special maintenance train pulled by either Rusty or Fred that is only used once a year. It consists of a flat truck with a large yellow tanker attached to it and a pipe hangs across the line behind the trucks' buffers. The pipes are designed so that weedkilling liquid is sprayed across the track.
The "Weedkiller" is based on the Talyllyn Railway's No. 60, 61 and 62 wagons, which for a time was fitted with a 120-gallon weedkiller tank. The wagon was built by the Ministry of Defence.
Flatbeds are used several times on the narrow gauge railway to carry and transport vehicles, engines and various objects.
The flatbed is based on the Talyllyn Railway 37.

Conflats are used several times on the narrow gauge railway to carry and transport vehicles, engines and various objects. There have been two types of these so far. In the Railway Series, the weedkiller train consists of a large tanker attached to a conflat. In the fourth series, Duke was transported to the Skarloey Railway via a conflat equipped with narrow gauge rails; the same type of conflat was later used for Skarloey. In the eleventh series, Rheneas accidentally bumped his conflats loaded with pipes when Thomas blew his whistle and surprised him. Rusty accidentally demolished a flat truck loaded with bricks when Thomas was playing a trick on him. In the twelfth series, Duncan delivered the Hot Air Balloon via a conflat.
The conflats are based on the Talyllyn Railway's No. 60, 61 and 62 wagon, which for a time was fitted with a 120 gallon weedkiller tank. The wagon was built by the Ministry of Defence.
Well wagons are used to carry tall loads like statues, to make them more stable or lower by placing the load in a dipped space between the bogies.
The well wagons are based on GWR 'Crocodile G' 35-ton bogie well wagons, scaled down accordingly.
Slab Wagons are commonly used on the Skarloey Railway, especially at the Blue Mountain Quarry. They are used to transport slabs of slate and are painted various colours. They have been seen since the sixteenth series.
The Slab wagons are based on the slate slab carrying wagons of the Maenofferen Quarry.
