Rocket - 1829 --- This famous 0-4-0 two-cylinder steam locomotive was built by Robert Stephenson & Co in 1829 at the Forth Sreet Works in Newcastle-upon-Tyne. Driving wheels 4' 8" diameter. Secondary wheels 2' 6" diameter. Cylinders 8" x 17" O/S. Originally the cylinders were mounted at 35 degrees to the horizontal (as shown in the drawing), but they were lowered sometime around 1831. This greatly changed the appearance of the locomotive. She was initially named "Premium Engine", but was renamed as "Rocket". It won the Rainhill Trials in October 1829, which were organised by the Liverpool & Manchester Railway. The revolutionary aspect of the design of "Rocket" was its boiler, which had a number of flues running through it, greatly increasing the heating area when compared to other designs. This technology quickly became standard across the world. In 1862 the locomotive was donated to the Patent Office Museum in London (now the Science Museum). The one photographed above by Abhi was at Chicago Science & Industries Museum which is a replica of the original one.
