Locomotive
In the beginning of transportation there were mainly horse and buggy, but then they developed a steam engine and they develop canals for steam boats. About five years later the people decided to start railroads because it was easier to lay and could be lain almost anywhere. So I will tell you about the steam engine, how it works, also about the steam locomotion, and I will present a model of an early British train. The old reciprocating steam locomotive is driven by a steam engine. Steam from the boiler is fed to the cylinders to move pistons back and forth (reciprocating motion). Connecting rods from the pistons then move the driving the driving wheels. The firebox at the rear end of the boiler is fed with coal or oil, which in a large locomotive is stored in a separate tender. The tender also contains the water that is directed up the smokestack to create a heavy draft for the boiler fire. The discharge of the used steam from the cylinders is c

They were only moderate efficient and were used mostly to transport ores through mines. By 1804 inventors were trying, but finding impractical, to use steam power to move railroad cars. About 20 years later , the Briton George Stephenson, a former engine mechanic, made steam engines a practical method of locomotion. Some steam locomotives weigh 500 tons(450 metric tons) or more and can develop more than 6,000 horsepower. They can pull a long train or a passenger train at about 100 miles(160 kilometers) per hour. For extremely heavy loads or steep grades, two or more locomotives may be coupled to a train.
