	Hump yard
		A hump yard (or: marshalling yard, classification yard) is a railroad yard found at some freight train stations used to separate railroad cars over a track upon an artificially built hill (hump) onto different tracks for each direction using gravity.
		The speed of the wagons rolling down from the hump into the classification bowl must be regulated because the different natural speed of each wagon (full or empty, heavy or light freight, number of axles) and the different filling of the tracks (whether there are actually few or already many wagons within it).
		Most hump yards are single yards with one classification bowl but some, mostly very large, hump yards have two of them, thus are double yards, such as Maschen or Bailey yards.

	Classification yard - Wikipedia, the free encyclopedia
		A classification yard or marshalling yard (including hump yards) is a railroad yard found at some freight train stations, used to separate railroad cars on to one of several tracks.
		Thus the cars must be shunted several times along their route in contrast to a unit train, which carries, for example, automobiles from the plant to a port, or coal from a mine to the power plant.
		The speed of the cars rolling down from the hump into the classification bowl must be regulated because of the different natural speed of the wagons (full or empty, heavy or light freight, number of axles) and the different filling of the tracks (whether there are presently few or already many cars on it).

	Farewell to Melbourne Yard NEWSRAIL October 1998
		Senior officers were sent to observe freight yard operations throughout the world and it was on their recommendation, that an agreement was reached to construct a hump yard to eliminate the problems of the existing yard.
		Although the yard was not fully automated to the extent of some of the larger yards in other countries, it was the type of yard which would meet the requirements in handling and sorting loading arriving into Melbourne.
		Unlike many overseas hump yards, where the hump is used for the marshalling of trains, the hump in Melbourne was used for the sorting of wagons arriving in Melbourne for distribution to areas around the city and metropolitan areas including the dock areas (Victoria, Appleton and Swanson), plus the inwards and outwards loading sheds.

		The tracks approaching the hump are laid on this incline with the grade rising towards the crest of the hump itself.
		Humping can be carried out in most of the bowl with maybe one group of classification tracks (or even just one track in that cluster) locked out.
		Some other railroads also used inert retarders in their hump yards and also in some flat switching yards where they were required to prevent roll outs owing to the geography of the land on which the yard was located.

	Selkirk Yard
		After yarding their train, inbound locomotives are uncoupled and proceed to the servicing facility where they are fueled and prepared for their next assignment.
		For the hump operation, a hump locomotive is positioned behind a train on a track in the receiving yard, as designated by the hump conductor, who then initiates the classification system by calling up from the computer the switch list for that receiving track.
		The departure yards are parallel to the classification yard.

	Union Pacific Yard Slugs
		The UP’s first yard slugs, with road numbers S1-S3, were built in 1973 and 1974 from three retired GP9Bs, and initially mated for hump service with three SD7s at Bailey Yard in North Platte, to fill the gap left by the retirement of the C630s.
		In addition to the North Platte yard complex in central Nebraska, UP also operated hump yards at East Los Angeles and Pocatello, and these two other yards were in need of the same economies provided by operating the slug sets at North Platte.
		GP38-2s in the 1800 class, 2100 class, and the former MKT units in the 2300 class were assigned to the yards in Hinkle, Pocatello, Fort Worth, and both the east bound and west bound hump yards at North Platte.

		A Yard was rebuilt with several tracks added to allow most of the classification of freight to be moved from E Yard.

	Humping from Railroaddave.com
		This yard being at the far end and away from the hump, it might've been a little quieter, except that the shanty was situated next to a stamping plant that operated twenty four hours seven days a week.
		The class yard, as most railroad yards, has a pronounced 'belly' - meaning that it is lower in the center of the yard.
		The ground that one walks on between the tracks in the hump yard is a mess.

		In making the choice, Yard Yard was considered not large enough for the new facility and the Harvard Yard near Marion, AR was considered an operational problem.
		Northbound cars that are humped pass over the crest three times, in the train arriving, in the cut pulling back to then be pushed over the crest and classified.
		This is a view of the bowl of the yard taken from the crest tower on September 1, 1980 during a tour of the yard

		Some yards, such as Lambton and West Toronto were designed with a very low hump, almost invisible, along with saucer shaped tracks that prevent cars from rolling out the other end.
		Initially, yard switching was supervised by a Train-Yard Co-ordinator (Co-ordinator), who controlled movements in and out of the yard in conjunction with train Dispatchers and the Operator, as well as co-ordinating work by the Hump Yardmaster, Retarder Operator, and Pulldown Supervisor.
		Yard C, the Classification yard, which has a total of 72 tracks, had one group of nine tracks (46-54) in the bowl left un-built for future expansion.

		Early Hump yards were very labor intensive and required one brakeman for each car or group of cars being classified.
		The number needed was in direct proportion to the size of the yard and the number of cars being classified in a given period of time.
		Normally the hump yards had motor cars that had bench seats on both sides of the car that were used to carry the brakemen back up to the crest.

		I was building a hump yard in Trainz and, in the absence of retarders, was satisfied with the way that handbrakes worked on cars, slowing them down a bit so I could apply and release the handbrake and smoothly couple the car to the consist.
		This is a big problem for me as I really enjoyed operating my hump yard.
		So now we are back to asking for, or trying to figure out how to make retarders or improving the car handbrake system.
