A railway is a system of tracks that trains use to travel from one place to another. It consists of steel rails laid on sleepers, which are supported by a foundation called ballast. Railways are used for transporting passengers and goods efficiently over long distances. Trains run on these tracks and can be powered by electricity, diesel, or steam. The railway system includes various components such as stations, signals, and switches to manage train movement. Railways play a crucial role in many countries' transportation networks, providing a reliable and cost-effective means of travel.
