By the Middle Ages, industry had developed to such an extent that traditional modes of transportation were no longer responsive, and artisans were trying to find new and effective ways. It was in 1556 that several German engineers built small rails to facilitate the movement of coal to guide coal trucks out of the mine. Initially, the rails were made of wood that did not have much strength; Hence, the wooden rails gradually gave way to cast iron strips, and this is how giant wagons were invented. Wagons that worked with the steam system and no longer needed manpower or animals to move. George Stevenson is a British mechanical engineer and railway inventor. He used the power of steam to propel a locomotive, creating this prestigious vehicle. Move the iron giant. If George Stephenson had not been born in a section of a coal mine in the north of England, he might never have thought of inventing a locomotive and a railroad train; Because he thought of inventing a locomotive and then a railroad, so that coal could be easily transported from the coal mine by a convenient means. If George Stephenson had not been born in a section of a coal mine in the north of England, he might never have thought of inventing a locomotive and a railroad train; Because he thought of inventing a locomotive and then a railroad, so that coal could be easily transported from the coal mine by a convenient means. If George Stephenson had not been born in a section of a coal mine in the north of England, he might never have thought of inventing a locomotive and a railroad train; Because he thought of inventing a locomotive and then a railroad, so that coal could be easily transported from the coal mine by a convenient means.
