Extracting Deadheads

Extracting allows you to create deadheads based on which ones may be needed according to your trip data.

Depending on the type of deadhead you chose on the Deadheads screen filter criteria, the Extract tab shows either a list of Line Groups (for Interline deadheads) or a list of Garages (for Garage deadheads) in the field on the top right section of the dialog box. The drop-down list is labeled appropriately depending on the selected type of deadhead.

  1. On the Deadheads tab, select the type of deadhead from which you want to extract: Interline or Garage.
  2. Click the Edit button: Edit button.
    The Edit dialog box appears.
  3. Click the Extract tab.
    The Delete and add option is selected by default.
  4. Choose the line group or garage whose deadheads you want to extract from the list on the top right section of the dialog box. type (labelled Line Group or Garages accordingly). If you selected Interline on the Deadheads tab, the list shows Line Groups and if you selected Garage, the list shows Garages.

    The To time of the last time interval you created appears automatically in the From Time field. This automatic feature makes it more convenient to add consecutive time intervals. If you prefer another From time, overwrite the automatic entry.

  8. Optional: To remove a time interval from the Time Breakdowns frame, select the interval you want to remove and click Remove.

    The system looks at your trip data, determines which deadheads are potentially needed, and adds them to the Extracted Deadheads frame.

    The selected deadheads and the times they are associated with are highlighted.
  11. Depending on how you want to apply the extracted data, select the appropriate option:
    • Delete and add- If there are any overlaps in the time intervals, the system deletes the old node to node or garage to garage pairs and adds the new pairs.
    • Add - If there are any overlaps in the time intervals, the system adds the new node to node or garage to garage pairs but does not remove the old pairs.
    • Do not add- If there are any overlaps in time intervals, the system does not add the new node to node or garage to garage pairs.
    These options work in the same fashion as the options on the Extract tab of the Node to Node Edit dialog box in the Trip Building screen.
