A rail yard , railway yard , railroad yard (US) or simply yard , is a series of tracks in a rail network for storing, sorting, or loading and unloading rail vehicles and locomotives . Yards have many tracks in parallel for keeping rolling stock or unused locomotives stored off the main line , so that they do not obstruct the flow of traffic. Cars or wagons are moved around by specially designed yard switcher locomotives (US) or shunter locomotives (UK), a type of locomotive. Cars or wagons in a yard may be sorted by numerous categories, including railway company , loaded or unloaded, destination, car type, or whether they need repairs. Yards are normally built where there is a need to store rail vehicles while they are not being loaded or unloaded, or are waiting to be assembled into trains. Large yards may have a tower to control operations.
8-422: Many yards are located at strategic points on a main line . Main-line yards are often composed of an up yard and a down yard, linked to the associated direction of travel . There are different types of yards, and different parts within a yard, depending on how they are built. For freight cars , the overall yard layout is typically designed around a principal switching (US term) or shunting (UK) technique: In
16-426: A fuelling point and other minor maintenance facilities. A good example of this was Newport 's Godfrey Road stabling point, which has since been closed. Stabling sidings can be just a few roads or large complexes like Feltham Sidings. They are sometimes electrified with a third rail or OLE . An example of a stabling point with third rail would be Feltham marshalling yard which is being made into carriage sidings for
24-714: A major US coach yard is Sunnyside Yard in New York City , operated by Amtrak . Those that are principally used for storage, such as the West Side Yard in New York, are called "layup yards" or "stabling yards." Coach yards are commonly flat yards because unladen passenger coaches are heavier than unladen freight carriages. In the UK, a stabling point is a place where rail locomotives are parked while awaiting their next turn of duty. A stabling point may be fitted with
32-677: A number of railway companies, with sidings and branches operated by private companies or single railway companies. Railway points (UK) or switches (US) are usually set in the direction of the main line by default. Failure to do so has been a factor in several fatal railway accidents , for example the Buttevant Rail Disaster in Ireland, and the Graniteville train crash in the US.

40-675: A trunk line, for example the Grand Trunk Railway in Canada, or the Trunk Line in Norway. For capacity reasons, main lines in many countries have at least a double track and often contain multiple parallel tracks. Main line tracks are typically operated at higher speeds than branch lines and are generally built and maintained to a higher standard than yards and branch lines. Main lines may also be operated under shared access by
48-558: The British Rail Class 701 EMU . Main line (railway) The main line , or mainline in American English , of a railway is a track that is used for through trains or is the principal artery of the system from which branch lines , yards , sidings , and spurs are connected. It generally refers to a route between towns, as opposed to a route providing suburban or metro services. It may also be called
56-399: The case of all classification or sorting yards, human intelligence plays a primary role in setting a strategy for the switching operations ; the fewer times coupling operations need to be made and the less distance traveled, the faster the operation, the better the strategy and the sooner the newly configured consist can be joined to its outbound train. A large freight yard may include
64-439: The following components: Freight yards may have multiple industries adjacent to them where railroad cars are loaded or unloaded and then stored before they move on to their new destination. Coach yards (American English) or stabling yards or carriage sidings (British English) are used for sorting, storing and repairing passenger cars . These yards are located in metropolitan areas near large stations or terminals. An example of
