Puffing Billy was one of the three similar engines built by engineer William Hedley, enginewright Jonathan Forster and blacksmith Timothy Hackworth, the resident engineer at Wylam Colliery, to replace the horses used as motive power on the tramway.
Definitive records regarding the construction of Puffing Billy do not exist. The exact construction dates are not known for certain, although it was known to be in operation during The chaldron was used as the measure for coal from the 13th century, measuring by volume being much more practical than weighing low-value, high-bulk commodities like coal.
It was not standardized, and there were many different regional chaldrons, the two most important being the Newcastle and London chaldrons.
The Newcastle chaldron was used to measure all coal shipped from Northumberland and Durham, and the London chaldron became the standard measure for coal in the east and south of England. Puffing Billy had a number of serious technical limitations. Running on cast iron Wagonway plates, its eight-ton weight was too heavy and broke them, encouraging opponents of locomotive traction to criticise the innovation.
