Steam
and Diesel Train Engines "All aboard!" Have you ever ridden on a train before?
Did you know that The first successful steam locomotive was built by Richard Trervithick in 1804. As the steam locomotive improved, more railroads
started to use But steam was a far cry from the luxuries of diesels and steam locomotive manufacturers knew that. They started to streamline their locomotives to make them look modern. Of course the streamlining didn't make the locomotive operate any better, but it did help the locomotive's image. Rudolph Diesel, inventor of the diesel engine, was born in Paris, France in The diesel locomotive was invented in the 1890's by Rudolph Diesel. By 1925, the diesel locomotive started to hit the rails. A diesel engine is a lot like a car engine; in fact it can be used in tractors, cars, trucks and many other pieces of machinery. The one difference between the internal-combustion engine that runs on gasoline and the diesel engine is that a diesel engine ignites the fuel without a spark. This happens when the piston in the engine compresses the air in the cylinder, and it gets hot. When the fuel is sprayed into the cylinder, it ignites forcing the piston to move. In a diesel-electric locomotive the diesel engine turns a generator. The generators send the power to the wheels. The electricity from the generator runs a motor which turns the wheels. The diesel locomotive started taking over steam in the 1950's. Some advantages diesels have over steam are that: diesels are cleaner, they don't need as much repair, they don't need to refuel as often as steam, and finally they are more powerful than steam. It might have taken two steam engines to haul a heavy train where one diesel can handle that train very well. Citations Books Stone, Lynn M. Steam Locomotives.
