The right answer is A and D, here some explanation:
He designed the famous and historic steam locomotive, being known as the father of the British railways and Father of the Railroad. Between 1822 and 1825 he built his first locomotive, which he called '' Active '' and later renamed '' Locomotion ''. The railway line was inaugurated on September 27, 1825. Driven by Stephenson, the Locomotion carried 80 tons of coal and took 2 hours to travel the 15-kilometer route, having reached 39 km / h in a part of the section. The first carriage designed to carry passengers was called '' Experiment '' and was also attached to the train. It was the first time passengers were transported in a vehicle powered by a steam locomotive.
During the construction of the railway lines, Stephenson noticed that however small the ascents were, the speed of the train decreased dramatically and that the descents made the brakes completely useless, since they could not stop the train. So he came to the conclusion that the railway lines should be as flat as possible. When he made the railways (Bolton - Leigh) and (Liverpool - Manchester), this knowledge led him to do a series of earthworks and to build stone viaducts, in order to make the routes smoother.
As the construction of the Liverpool-Manchester railroad was drawing to a close, its directors organized a competition to decide who would build the locomotives to operate on the line. The race took place in October 1829. Stephenson's '' Rocket '' had an impressive performance and won the race, becoming without a doubt the most famous machine in the world.
