When rail workers are laying train tracks, they often use a flat-bottom steel rail that resembles the steel I-beam girders of construction. The rail has a wide base or foot, a narrow web and a head (wider than the web, but not as wide as the foot). The weights of the rails vary...
Today's Cummins Diesel Engines Cummins diesel engines are the most powerful and reliable engines on the road, on the water and at the worksite. Ranging from 2.8 to 95 liters of displacement, our diverse engine lineup allows customers around the globe to leverage the perfect Cummins engine for...
Gas engines, also known as gasoline engines, are commonly found in cars. They work by igniting a fuel-air mixture with a spark plug. The intake stroke creates a vacuum, drawing in the mixture. During the compression stroke, the mixture is compressed, and when ignited, combustion occurs, gen...
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 ...
training you’ve been doing lately compared to your usual level. If you keep overreaching, you’ll be more prone to sports-related injuries. You may also fall ill more easily. This doesn't mean you’re bound to get injured or fall ill, but the odds are that you’re not ready for ...
Similarly, the control/command implemented byAgate Control™and Agate Net™ solutions are demonstrating that Alstom is handling components in a smarter way, particularly through the extensive use of the latest digital technologies. Within the train system, the control and command system provides an...
The valve train consists of the valves and a mechanism that opens and closes them. The opening and closing system is called a camshaft. The camshaft has lobes on it that move the valves up and down, as shown in Figure 5. Most modern engines have what are called overhead cams. This mea...

Battery-Electric Locomotives:Railroads are testing and piloting battery-powered locomotives in switching yards to potentially replace over-the-road diesel engines at some point in the future. Hydrogen Fuel Cell Locomotives:Railroads are also researching the use of hydrogen fuel cell locomotives for lo...
