In p>1783, Watt's student Murdoch built a car powered by a steam engine, but the effect was not good and no one used it. In 187, Englishmen Trevisick and Vivian successfully built a car propelled by a steam engine, but the car was too heavy to walk on ordinary roads, and they didn't expect to put it on the rails, so they soon abandoned it. It was not until 1814 that Stephenson, a British engineer who was a cowherd, built a steam locomotive walking on the rails and officially invented the train.
Another way of saying it
In p>181, the inventor Terry Vissec first built a steam-powered vehicle running on ordinary roads, and applied for a patent the following year. On this basis, he transformed Watt's steam engine into a high-pressure steam engine, and successfully made a locomotive that could run on the track with this steam engine. On February 29th, 184, Terry Vissec's locomotive drove from Mercer to Aberdeen along a special track, creating a glorious journey of the world's first steam car. Ten years later, Stephenson, a famous British inventor, made and modified a similar locomotive, laid the rails and began to use it in coal mines. In this way, future generations will regard him as the inventor of the train.
