Noun

Singular railroad

Plural railroads

railroad (plural railroads)

1. A permanent road consisting of fixed metal rails to drive trains or similar motorized vehicles on.

   Many railroads roughly follow the trace of older land - and/or water roads

2. The transportation system comprising such roads and vehicles fitted to travel on the rails, usually with several vehicles connected together in a train.
3. A single, privately or publicly owned property comprising one or more such roads and usually associated assets

   Railroads can only compete fully if their tracks are techically compatible with and linked to each-other

4. (figuratively) A procedure conducted or bullied in haste without due consideration.

Railroad transportation is the means of conveyance of passengers and goods by way of wheeled vehicles running on rail tracks. In contrast to road transport, where vehicles merely run on a prepared surface, rail vehicles are also directionally guided by the tracks they run on.

Track usually consists of steel rails installed on sleepers/ties and ballast, on which the rolling stock, usually fitted with metal wheels, moves. However, other variations are also possible, such as slab track where the rails are fastened to a concrete foundation resting on a prepared subsurface.

Rolling stock in railroad transportation systems generally has lower frictional resistance when compared with highway vehicles, and the railroad cars can be coupled into long trains.

The operation is carried out by a railway company, providing transport between train stations or freight customer facilities. Power is provided by locomotives which either draw electrical power from a railway electrification system or produce their own power, usually by diesel engines. Most tracks are accompanied by a signaling system.

Railroads are a safe land transportation systems when compared to other forms of transportation. Railroad transportation is capable of high levels of passenger and cargo utilization and energy efficiency, but is often less flexible and more capital-intensive than highway transportation is, when lower traffic levels are considered.

The oldest, man-hauled railways date to the 6th century B.CE. With the development of the steam engine, it was possible to construct mainline railways, that were a key component of the industrial revolution. Also, railroads reduced the costs of shipping, and allowed for fewer lost goods. The change from canals to railroads allowed for "national markets" in which prices varied very little from city to city. Studies have shown that the development of the railroad was one of the most important technological inventions of the late 19th century in the United States, without which, GDP would have been lower by 7.0% in 1890. In the 1880s, electrified trains were introduced, and also the first tramways and rapid transit systems came into being. During the 1940s and 1950s, the non-electrified railways in most countries had their steam locomotives replaced by diesel-electric locomotives. During the 1960s, electrified high-speed railroad systems were introduced in Japan and a few other countries. Other forms of rail transportation outside the traditional definitions, such as magnetic-levitation maglev trains have also slowly came into use.
