Stephenson did not invent the steam engine! The steam locomotive invented by Stephenson is known as the "Father of Railway Locomotives".
In 1810, Stephenson began to build steam locomotives. After several years of hard work, he finally invented a steam locomotive in 1814, which was called the "Traveler". It kept emitting fire from the chimney as it moved forward, so it was called the "Train".
The first railway was built in Britain in 1825. In September of the same year, the "Traveler" locomotive towed more than 30 small carriages and was officially tested. The carriages carried 450 passengers and 90 tons of cargo. "No." train completed a distance of 40 kilometers at a speed of 24 kilometers per hour.
In 1829, Stephenson built the steam locomotive "Rocket" with a speed of 58 kilometers per hour.
The inventor of the steam engine is usually thought to be Scottish inventor James Watt.
In fact, Watt was not the first person to invent the steam engine. Alexander Hero designed a similar machine in the first century AD.
The first steam engine was invented and manufactured by French physicist Denis Papin in 1688 with a cylinder and piston. In 1698, Thomas Savery patented the use of a steam engine to pump water. In 1712, Englishman Thomas Newton patented a slightly improved steam engine. The Niukaomen steam engine was very inefficient and could only be used for coal mine drainage.
Watt was the inventor of the improved steam engine and a key figure in the Industrial Revolution.
