Stephenson's Rocket was an early steam locomotive of 0-2-2 wheel arrangement, built in 1829 at the Forth Street Works of Robert Stephenson and Company in Newcastle Upon Tyne.
It was built for, and won, the Rainhill Trials held by the Liverpool & Manchester Railway in 1829 to choose the best design to power the railway.
Though the Rocket was not the first steam locomotive, it was the first to bring together several innovations to produce the most advanced locomotive of its day.
It is the most famous example of an evolving design of locomotives by Stephenson that became the template for most steam engines in the following 150 years.
Design
[edit] Basic layout
The locomotive had a tall smokestack chimney at the front, a cylindrical boiler in the middle, and a separate firebox at the rear. The large front pair of wooden wheels was driven by two external cylinders set at an angle. The smaller rear wheels were not coupled to the driving wheels, giving an 0-2-2 wheel arrangement.[3]
