Hump Yard
A marshalling yard used in hump shunting.

HUMP"Artificial knoll at end of classification yard over which cars are pushed so that they can roll on their own momentum to separate tracks. (See drop.) Also the summit of a hill division or the top of a prominent grade.
Hump yard
Classification yards where strings of freight cars are slowly pushed over a hump, or small hill. When they reach the crest of the hump, the cars are uncoupled according to which track they are destined for.
Hump Yard
Railroad classification yard in which the classification of cars is accomplished by pushing them over a summit, known as hump, beyond which they run by gravity

Hump
An elevated section of track from which free-wheeling freight cars can be coasted by gravity for classification in the yards below.

Hump Yard
A switching yard on an incline where, after movements by the engine, the cars are shunted by gravitational pull to their destination in a yard.

A hump yard (or: marshalling yard, classification yard) is a railroad yard found at some freight train stations, used to separate railroad cars via a track upon an artificially built hill (hump) onto different tracks for each direction using gravity.
See Hump.
Re-triggerable One-Shot
Timing feature where the off-delay is a fixed time interval, but can be reset by a change in input.
Some hump yards are huge. Conrail's hump yard in Elkhart, IN (which is now part of Norfolk Southern) has some seventy-six classification tracks with all of them being fairly long.
Hump A rail yard with a hill. Cars are cut off in motion at the top of the hump and gravity pulls the cars to the classification tracks.
I
Independent Break The brake control on a locomotive used to control the locomotives air brakes.
Hump - An elevated section of track down which freight cars can be coasted for classification in the yards below.
Hump: A raised section in a rail sorting yard that allows operators to use gravity to move freight railcars into the proper position within the yard when making up trains of cars (that is, humping the cars).
Bar code labels are fastened to the bottom of the rolling stock, and your computer can read the car numbers as they pass by (maybe even throw the turnouts automatically in that working hump yard to select the correct track for each car too!).
Hump Yard
RAILWAYS. A freight yard where wagons are sorted by pushing them over a hill (hump) and letting them roll down under gravity, not coupled to a locomotive, to the desired tracks via a number of junctions.
House Track A track entering, or along side a freight house. Cars are spotted here for loading or unloading. Hump A rail yard with a hill.
Was also used in the UK to refer to the sections a train was broken into when passing over a hump in a marshalling yard. Since there isn't any hump shunting in the UK any more I suppose this is obsolete.
Figure 69 presents the most interesting possibilities for freight handling and future expansion. The three sidings in the center can be graded for "hump" classification yards. The track shown dotted at the left indicates that it is beneath a mountain.
Uncoupling Ramp A ramp fitted under or between the rails on a model to facilitate the remote uncoupling of rolling stock. It has no prototype equivalent except where used in hump shunting yards.
If you intend to use Kadee or other magnetic knuckle couplers, it's handy to take a tip from prototype railroads and build a "hump" yard. That is, put the uncoupler on a gentle slope so that uncoupled cars roll gently away from the mainline.
As you can see, short cuts won't work on this project. Sorry. One big secret is to get the bridge and both approaches flat to each other. You don't want a big dip or hump where the bridge and ground meet.
Generally used in yard duty where the switcher has enough horsepower, but not enough tractive force to push long strings of cars up a hump.
