Add Location as Yards and the Add Location window for Yards is opened from Add Location window.

To add a location as a Yard: in the Add Location window, type the Name of the Yard location, note most of the window is greyed out until the location is added. The location name must be unique; the program will not allow two locations with identical names. However, if you want more than one location to have the same name for your manifests and switch lists, add a hyphen and a number to the locations name. For example, "Boston-1" and "Boston-2" will print as "Boston". The program will remove the hyphen and number when printing manifests and switch lists.

Select Operations at this location Yards, then press the at the bottom of the window.


Opens the Add Location window with options activated.


A classification yard (US and Canada) or marshalling yard (UK and Canada)(including hump yards) is a railroad yard found at some freight stations, used to separate railroad cars on to one of several tracks. First the cars are taken to a track, sometimes called a lead or a drill. From there the cars are sent through a series of switches called a ladder onto the classification tracks. Larger yards tend to put the lead on an artificially built hill called a hump to use the force of gravity to propel the cars through the ladder.

Freight trains that consist of isolated cars must be made into trains and divided according to their destinations. 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. This shunting is done partly at the starting and final destinations and partly (for long-distance-hauling) in classification yards.

A yard will contain several tracks that must be defined.

Now after selecting all of the options for the yard, click on and the Add Yard Track window opens.
