Trials were conducted at Rainhill, near Liver- pool, on a level piece of the line 1J miles in length, of which 220 yards at each end were allowed for starting and stopping. The competing engines were required to make ten double trips, going over the cen- tral 1^ miles at full speed, which was to represent a journey from Manchester to Liverpool, Then a fresh supply of water and fuel could be taken up and the second ten trips performed, which rep- resented the return journey. The average speed throughout had to be no less than 10 miles an hour. " The Rocket" was the onl}- en-. no. ^9.

She completed the whole of the double journey at an average speed over the central portion of the track of miles an hour, her maximum speed for one trip being 24,1 miles an hour. The engine ran on four wheels and had two cylinders 8 inches in diameter by 17 inches stroke placed at the rear end of the boiler and inclined downward at 37 degrees with the horizontal; the piston rods drove the front wheels, which were inches in diameter, thus giving a tractive factor of The trailing wheels were 34 inches in diameter and the wheel base feet. The cylinders were mounted on iron plates which were bolted to the boiler shell and sup- ported by stays; these plates also carried the guide bars, which were of square section set diagonally, while the erossheads were of brass, in halves, bolted together and embracing the bars. The steam chests were below the cylinders and the slide valves were driven through an intermediate shaft and levers by. Please note that these images are extracted from scanned
