The Showmans' engine is considered
by many to be the ultimate form of the traction engine. It is a specialised
road haulage engine with modifications to make it suitable for Showmans'
use. There is a large dynamo mounted on an extension to the smoke box, which
is belt driven from the flywheel.
An extended canopy covers the
length of the engine supported by traditional brass barley twist staunchions,
with the brass capped chimney passing through.
An extension to the chimney is
usually mounted on the roof, to be used for extra draught, necessary when
working stationary. Added decoration includes brass stars to the motion
covers and belly tank, extra brass boiler bands. Optional signwriting,
lining and canopy lighting add the finishing touch.
