  Line	No	N/A
  Line	Yes	N/A
  Point	No	N/A
  Point	Yes	N/A

  Modified Event for a Continuous Network

  Event type	Supports route name	Supports spanning routes
  Line	Yes	N/A
  Line	No	N/A
  Point	Yes	N/A
  Point	No	N/A

  Present Event for an Engineering Network

  Event type	Supports route name	Supports spanning routes
  Line	No	No
  Line	Yes	No
  Line	Yes	No
  Line	Yes	Yes
  Point	No	N/A
  Point	Yes	N/A

  Modified Event for an Engineering Network

  Line	Yes	Yes
  Line	Yes	No
  Point	Yes	N/A
  Point	No	N/A
