Shunt moves are considered those which occur semi randomly, usually within a depot which may be partially visible to the signaller in SimSig. They are not intended for main line moves as they do not have a scheduled journey time - they are effectively very short, untimetabled movements used, for example, to move a train from one siding to another within a depot.
Set up a train schedule in the usual place. It is recommended to use 0S00 as the headcode for a shunt move. An entry point (not seed point) must be selected but the entry time should be zero/midnight. Enter locations in order that the train will complete its movements and exit the simulation (usually back in the same depot). Activities are allowed but joins are not recommended due to the random nature of its appearance.
Tick/check the box labelled "Shunt move" (on the Train Details page). Move to the Misc page and decide whether the train should always request permission to enter, and/or whether a headcode is automatically interposed (if the entry point supports it). Moves within depots are rarely given headcodes so most likely this would be unticked.
Shunt times should be entered which define when, and how often, shunt moves are randomly generated. Multiple time ranges can be defined but they should not overlap (results are unpredictable if they do overlap). For example, you could have a busy period from 4am to 5am, then quieter during the day, and then busy again from 9pm to 10pm.
Time period options are defined by the following parameters: Start time, end time, minimum interval, and maximum interval. For example, given a range of 8am to 9am with min/max of 10/20 would mean somewhere between 3 and 6 random shunt moves will appear.
