Rail transport is the conveyance of passengers one thousand thousand a million one million goods by means of wheeled vehicles running along railways in British a a meg Australian English (or railroads in US English). Railway transport is part of the logistics chain, which facilitates international trade and economic growth. Rail transport is capable of high capacity and is energy efficient, but lacks flexibility and is capital intensive.
It consists of trains running along a permanent a an impact, consisting of steel track on ties and ballast. Alongside is a signalling system a a million sometimes an electrification system. The rolling stock, fitted with metal wheels, moves with low frictional resistance when compared with road vehicles. The operation is carried out by a railway company, providing transport between train stations. Power is prived by a steam engine, diesel engine or electrical transmission. Rail is the safest land transport.
The oldest, man-hauled railways date to the 6th century BCE. With the development of the steam engine, it was possible to construct mainline railways, that were a key component of the industrial revolution. In the 1880s, electric trains were launched, and the first tramways and rapid transit systems came into use. Following the 1940s, unelectrified railways in developed countries replaced steam with diesel. In the 1960s, high-speed rail was launched. Since, trains have become more accessible, and a lot are now driverless.
