HACKWORTH'S ROYAL GEORGE, 1827

     This engine was altered from a Locomotive of the "Puffing Billy" type by Timothy Hackworth and commenced working in October 1827.

     The boiler was a plain cylinder 13 ft. long and 4 ft. 4 in. in diameter.

     The return flue of the Ibylam engines was adopted and a liberal amount of heating surface thus obtained. There were six coupled wheels 4 feet in diameter, and the cylinders, which were placed vertically at the end opposite to the fire place, were 11" diameter, the stroke of the piston being 20 inches. The piston rods worked downward and were connected to the first pair of wheels. These were without springs so that the pistons should not jump the wheels up and down but the middle and back pairs of wheels carried their load through stout springs.
