The "Trucks"/Behind the Scenes

The Railway Series
The "Trucks" are fictional narrow gauge mountain rolling stock created by the Rev. W. Awdry. The "Trucks" are made up of two components. The small passenger/Guard's compartment is the sentient portion of the train, is female and simply referred to as "The Truck".

In the main book series, the "Trucks" only appear in Mountain Engines - published 1964. However, their last illustrated appearances were in the Famous Engines, and were last mentioned in Sodor: Reading Between the Lines published in 2005. According to Christopher Awdry, the reason there are no more books about the Culdee Fell Railway is due to the safety precautions and limited traffic - meaning no more story opportunities.

Television Series
Mountain Engines was the first book of the Railway Series not to have any of its stories televised. According to an interview with Robert Gauld-Galliers, this could be attributed to limited storylines, rack-and-pinion track, the engines' strange-angled body, and being not very merchandisable.

In 2012, the Culdee Fell Railway was mentioned in a Blue Mountain Mystery promotional video about the differences between the narrow and standard gauge. In a 2015 interview, Sam Wilkinson stated the "Culdee Fell Railway have always been on the list to be created, ever since I joined, but these would always require a lot of time, resources, and money to create. Also there is no live-action reference so everything would have to be done from scratch". Sadly, this never came to fruition.

Both parts of the Truck were released under Wooden Railway, however the passenger compartment was depicted with Catherine's face and released under her name.
