The first railways were only used to transport coal. George Stephenson (1781-1848) owned a company in Newcastle that specialised in building railway trains to transport coal like this. Stephenson saw that passengers might travel in the same way as coal and designed the Locomotion 1 train engine, which was powerful enough to pull carriages. Locomotion 1 transported the first steam railway passengers from Stockton to Darlington in the northeast of England in 1825. -
The steam hammer was crucial in factories. Developed in 1839 by the Scotsman James Nasmyth (1808-1890), this relatively simple device used a steam engine to let fall (and later push) with a precision of both speed and direction a great weight capable of forging or bending large pieces of metal resting on an adjustable anvil plate. -
The process is named after inventor Henry Bessemer (1813-1898), who patented the technique in 1856. The Bessemer process was the world's first inexpensive process for the mass production of steel from molten pig iron.The ability to mass-produce high-quality steel and iron allowed a literal boom in using them in many other aspects of the revolution. Iron and steel became essential for almost everything, from appliances to tools, machines, ships, buildings, and infrastructure. -
