Like the Lancashire Witch, Rocket had two cylinders set at angle from the horizontal, with the pistons driving a pair of 4 ft 8.5 in (1.435 m) diameter wheels.
Most previous designs had the cylinders positioned vertically, which gave the engines an uneven swaying motion as they progressed along the track.
Subsequently, Rocket was modified so that the cylinders were set close to horizontal, a layout that influenced nearly all designs that followed.
