Steam Wagons
The very first steam road vehicle was in fact a wagon of 1769 built by Cugnot in
Paris. Steam wagons developed into two distinct forms the Overtype and
Undertype. The Overtype wagon had its motion work and cylinder on top of a
locomotive type boiler in the same fashion as a traction engine. The Undertype
wagons normally had a vertical boiler with the engine mounted under the wagon
floor away from the boiler. There is a lot of debate as to who produced the best
type of wagon. Fodens and Sentinel were the predominant makers of wagons in
Great Britain. Compound working was most common and traction engine gears were
used to provide final drive via one or two chains which were often of great
length and were exposed to the elements.
