Gravity yard . Gravity yards were invented in the 19th century, saving shunting engines and instead letting the cars roll by gravity was seen as a major benefit, whereas the larger amount of manual work required to stop the rolling cars in the classification tracks was judged to be not that important. Gravity yards were a historical step in the development of classification yards and were later judged as inferior to hump …

The classification yard can be flat switched or may use a hump to speed switching. It may have switch ladders at one or both ends

    Without railroad yards it would be virtually impossible for railroads to remain efficient in keeping freight exactly where it needs to go. These large terminals, commonly known as classification yards, take in freight, usually from all different directions, sort it out and again send it on its way to either the next yard or final destination

    Hump yards are the largest and most effective classification yards, with the largest shunting capacity, often several thousand cars a day. They work similarly to gravity yards, but the falling gradient is limited to a small part of the yard, namely the hump. It is the heart of the yard—a lead track on a small hill over which an engine pushes the cars

    Gravity yards were a historical step in the development of classification yards and were later judged as inferior to hump yards, because it became clear that shunting engines were needed anyway (at least in inclement weather like strong winds or icy temperatures when the oil in the bearings became thick), and because manual labour was getting relatively more and more expensive

    Most gravity yards were built in Germany and Great Britain, sometimes also in some other European countries. In the USA there were only very few old gravity yards; none seem to be in operation today. The largest active gravity yard is Nürnberg Rbf (Rbf: Rangierbahnhof, "classification yard"), Germany. Gravity yards also have a very large capacity but they need more staff than hump yards and thus they are the …
