there is still immense interest in steam traction, as demonstrated by the increasing numbers of privately renovated and preserved locomotives and heritage railways around the world. In How Steam Locomotives Really Work, the authors, both railway experts, cover the design of locomotives, the many ...

Diesel-electric systems are also five times more efficient than the old steam engine locomotives, which is why diesel entirely replaced steam in the early 20th century. Diesel also has seen some competition from fully electric trains, which pull directly from a power grid as they drive. This ...
Steam locomotives were powered bysteam engines, and deserve to be remembered because they swept the world through the Industrial Revolution of the 18th and 19th centuries. Steam engines rank with cars,airplanes,telephones,radio, andtelevisionamong the greatestinventionsof all time. They are marvels ...
Steam shovels could move from one location to another -- but it often took a long time to get there. ©iStockphoto/Thinkstock So how exactly do these boiling behemoths work? As you might guess, the driving force behind them is their clever use ofsteam, starting with the boiler and gi...
The piston pushes the locomotive's wheels around before returning back into the cylinder so the whole process can be repeated. The steam isn't a source of energy: it's an energy-transporting fluid that helps to convert the energy locked inside coal into mechanical energy that propels a ...

Image Courtesy: The Physics of Electric Locomotives The Diesel vs Electric Question By around the end of the 1950s when it had become clear that the future did not lie in steam traction and it had to be done away with, the question arose on what technology of locomotive propulsion we shou...
How Steam Engines Work To understand a basic steam engine, let's take the example of the steam engine found in an old steam locomotive like the one depicted. The basic parts of the steam engine in a locomotive would be a boiler, slide valve, cylinder, steam reservoir, piston, and a dri...
