Stephenson's Rocket is an early steam locomotive of 0-2-2 wheel arrangement. It was built for and won the Rainhill Trials of the Liverpool and Manchester Railway (L&MR), held in October 1829 to show that improved locomotives would be more efficient than stationary steam engines.
Rocket was designed and built by Robert Stephenson in 1829, and built at the Forth Street Works of his company in Newcastle upon Tyne.
The Liverpool and Manchester Railway (L&M) opened on 15 September 1830. Work on the L&M had begun in the 1820s, to connect the textile mills of the city of Manchester with the nearest deep water port at the Port of Liverpool, 35 miles (56 km) away. Although horse-drawn railways already existed elsewhere, the Stockton and Darlington Railway had been running for five years, and a few industrial sites already used primitive steam locomotives for bulk haulage, the L&M was the first locomotive-hauled railway to connect two major cities, and the first to provide a scheduled passenger service. The opening day was a major public event. Arthur Wellesley, Duke of Wellington, the prime minister, rode on one of the eight inaugural trains, as did many other dignitaries and notable figures of the day. Huge crowds lined the track at Liverpool to watch the trains depart for Manchester.
The trains left Liverpool on time and without any technical problems. The Duke of Wellington's special train ran on one track, and the other seven trains ran on an adjacent and parallel track, sometimes ahead and sometimes behind the duke's train. Around 13 miles (21 km) out of Liverpool the first of many problems occurred, when one of the trains derailed and the following train collided with it. With no reported injuries or damage, the derailed locomotive was lifted back onto the track and the journey continued. At Parkside railway station, near the midpoint of the line, the locomotives made a scheduled stop to take on water. Although the railway staff advised passengers to remain on the trains while this took place, around 50 of the dignitaries on board alighted when the Duke of Wellington's special train stopped. One of those who got off was William Huskisson, former cabinet minister and Member of Parliament for Liverpool. Huskisson had been a highly influential figure in the creation of the British Empire and an architect of the doctrine of free trade, but had fallen out with Wellington in 1828 over the issue of parliamentary reform and had resigned from the cabinet. Hoping to be reconciled with Wellington, he approached the duke's railway carriage and shook his hand. Distracted by the duke, he did not notice an approaching locomotive on the adjacent track, Rocket. On realising it was approaching, he panicked and tried to clamber into the duke's carriage, but the door of the carriage swung open, leaving him hanging directly in the path of the oncoming Rocket. He fell onto the tracks in front of the train, suffering serious leg injuries, and died later that night.
The cylinder is the power-producing element of the steam engine powering a steam locomotive. The cylinder is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were initially cast iron, but later made of steel. The cylinder casting includes other features such as (in the case of Stephenson's Rocket) valve ports and mounting feet. The last big American locomotives incorporated the cylinders as part of huge one-piece steel castings that were the main frame of the locomotive. Renewable wearing surfaces were needed inside the cylinders and provided by cast-iron bushings.
The way the valve controlled the steam entering and leaving the cylinder was known as steam distribution and shown by the shape of the indicator diagram. What happened to the steam inside the cylinder was assessed separately from what happened in the boiler and how much friction the moving machinery had to cope with. This assessment was known as "engine performance" or "cylinder performance". The cylinder performance, together with the boiler and machinery performance, established the efficiency of the complete locomotive. The pressure of the steam in the cylinder was measured as the piston moved and the power moving the piston was calculated and known as cylinder power. The forces produced in the cylinder moved the train but were also damaging to the structure which held the cylinders in place. Bolted joints came loose, cylinder castings and frames cracked and reduced the availability of the locomotive.

He is commonly known as the world's first widely reported railway passenger casualty, since he was run over and fatally injured by Robert Stephenson's pioneering locomotive Rocket at the opening of the Liverpool and Manchester Railway in 1830. However, a number of fatal railway accidents had already occurred before this.
