OpenRail Designer CONNECT Edition

Existing Cant Workflow

  1. If the create centerline from rails tool is used, then the existing cant for that centerline is automatically created, and displays automatically in the horizontal regression space view. The cant uses center rotation as there is no geometry to use for the Inside/Outside rotation methods.
  2. Once horizontal geometry for the centerline is created, a profile applied (profile MUST be applied), speed table created and cant applied, then when the Edit Cant tool is used, a toolbar button, Select Existing Rail,s becomes available.
  3. Use this button to select the Left and Right Existing Rails. The cant according to the cant rotation method applied when applying the cant to the geometry displays in the diagram for the left and right rail.
  4. Display in curvature diagram.
    1. Import rail readings from existing data and sort points.
    2. Using the OpenRail Modeling > Rail > Regression > Convert Rails to Centerline tool select the centerline geometry.
    3. Select left rail then select right rail.
    4. Centerline displays based on left and right rail.
    5. Select curvature diagram to perform horizontal curvature on centerline.
    6. Select centerline then Display Existing Cant, if it exists.
    7. Select regression view to show standard regression curve.
    8. Shows curvature changes with station. Also shows existing cant.
    9. The existing cant is read-only to use as a guide when performing horizontal regression plus helps to determine points for centerline geometry.
  5. Display in cant editor.
    1. Perform horizontal regression on centerline.
    2. Apply speed table.
    3. Select create cant to create cant for the speed table.
    4. Select edit cant.
    5. Locate the cant element.
    6. Cant editor displays.
    7. Select add existing cant button .
    8. Select existing left and right rail used to create the centerline.
    9. Superelevation display list, red is left rail existing cant and yellow is the right rail existing cant. Turn on or off, if desired.

      OR

      Select inside rail which is the default.

    10. Create cant. Specify rotate about inside rail.
    11. Select Edit cant. Select existing cant.
    12. Select existing left rail then select existing right rail.
    13. Superelevation display list, red is left rail existing cant and yellow is the right rail existing cant. Turn on or off, if desired.
