This six wheeled coach is a representation of the many which served on the North British Railway (NBR) in the late 19th and early 20th century. Small coaches such as this six wheeled coach proved especially good at branch line work where their small size enabled the traversing of tight radius curves, whilst lower passenger numbers meant their small size was more acceptable and enabled trains to be hauled by smaller engines.
This NBR coach is modelled as having step boards to enable access at stations with low platforms and gas lamp lighting.
