The Locomotive

The first steam locomotive to run on rails was seen in Wales in 1804. Designs were greatly improved in the 1820s by English rail pioneer George Stephenson. Railroads were soon opening up the world. Although prototypes had previously been created, the first full scale steam locomotive was built in Britain by British engineer Richard Trevithick in 1804. Unfortunately his steam locomotive was not well received. In 1814, the first successful steam engine locomotive was built by the British Engineer George Stephenson called Blücher, which could haul up to 30 tons of coal at 4mph going uphill. Later in 1825, Stephenson also created the first public railway for steam locomotives. The steam powered engine is the heart of the steam locomotive. The fire is used to heat the water which in turn creates the steam that causes the wheels to turn. Fire tube boilers that were commonly used in steam locomotives here typically built horizontally. Near the rear of the boiler was the firebox. The firebox is the area on the boiler where the fuel is burned and is made with a door that could be opened to add coal or wood for fuel. The heated gases pass through metal tubes that are submerged in the boiler's water and converts the water into steam. This steam can be released manually if the pressure becomes too high, or it can be released into the steam pipes into a cylinder where it moves the pistons. The pistons are connected to the wheels. As the valves release the steam onto the pistons, the wheels move.
