(See table, above)

4.Minutes of Previous Meeting

- Corrections in the attachment related to version numbering were corrected.

- Approval – Approved after corrections

5.Progress Report by Chair (Dave Thurston)

The overall progress of the Working Group is satisfactory. This is the 7th meeting of the Group, and response to action items remains strong. The Guideline is on schedule for a Group recommendation for approval in late fall. In addition, there has been progress on the Working Group PAR. The PAR is on the agenda of the Standards Board for the September meeting.

6.Policies and Procedures

Dave Thurston reviewed the IEEE policies on patentable materials.

The next steps within the Guideline approval process were reviewed. Subsequent actions items were assigned.

7.Membership Renewals

Membership requirements for Guideline balloting were discussed and reviewed.

8.Work in Progress- Previous action Items were discussed with the following results:

  1. Don S. will contact John E. to re-examine Annex B and develop graphs for distance versus time curves (versus tractive effort versus time) with regards to propulsion removal, dead time (coast) and brake build-up. (Not completed, the text was modified during the meeting, and the graphics are to be modified by Dave T.)
  2. At the conclusion of the work on the draft guideline, all units within the document must be converted to appropriate metric equivalents. (ALL)
  3. Dave T. to contact Joanne Shepanski of the SYSTRA Chadds Ford office, and coordinate with the IEEE for completion of the PAR for WG 25. (in progress)
  4. Dave P. will look into the formatting for bibliographical references for the Hay book to be used. (completed)
  5. Dave P. to look into the formatting for citing bibliographical references in the body of the guideline. (completed)
  6. Dave T, and D. Phelps to advance sign off for SA Board agenda item for completion of the PAR for WG 25. (completed)
  7. Dave T. to provide Annex D showing examples of the guidelines for different type of applications. (Discussed at length. Dave T. to rework the graphics and add a profile aka. Distance to go type sample)
  8. Capture the results of Action Items completed prior to the next meeting such that a D0.10 can be created. This D0.10 will be discussed at the next meeting. If possible, it will be distributed in advance of the meeting. – Dave P. (completed)

The draft version D0.10 was discussed in detail in association with the previous action items from Meeting #6. The full body of D0.10 was reviewed, including the annex details. The results of today’s meeting are captured in D0.11 which will be distributed with the minutes.

9.Work Plan

- The following action items were assigned for discussion at the next meeting

  1. The graphics for the Propulsion annex will be reworked.(Dave T.)
  2. At the conclusion of the work on the draft guideline, all units within the document must be converted to appropriate metric equivalents. (ALL)
  3. Dave T. andJoanne Shepanski of the SYSTRA Chadds Ford office to coordinate with the IEEE for completion of the PAR for WG 25.
  4. Dave T. to provide another Annex D sample showing the application of the braking distance model for profile or distance to go type train control.
  5. Capture the results of Action Items completed prior to the next meeting such that a D0.12can be created. This D0.12will be discussed at the next meeting. If possible, it will be distributed in advance of the meeting. – Dave P.

Date and location for the next meeting: The next meeting will be scheduled to coincide (the previous or following day) with the RTVISC Committee meeting (Dave T. to contact Jim Deitz)
