N Gauge Coalbrookdale Engine

Description

This model is of Trevithick’s 1802 Coalbrookdale Engine.  Whether the prototype was actually built or not is unknown, but nonetheless it holds the accolade as the first ever steam railway locomotive, predating his 1804 Pen-y-Darren engine. 
 
Two versions are available (both with a strip of scale plateway track) – one-piece static model or a kit of parts capable of producing an unpowered but working engine.  Also available is a matching truck and further plateway track, enabling construction of a complete diorama. 
 
Details of construction for the working version can be found in the video below.
