A steam wagon (steam lorry or steam waggon) is a steam-powered road vehicle for carrying freight. It was the earliest form of lorry (truck) and came in two basic forms: overtype and undertype – the distinction being the position of the engine relative to the boiler. Manufacturers tended to concentrate on one form or the other.
