Minutes of Meeting:
1.0 HOUSEKEEPING ITEMS
1.1 Introductions
Alan Rumsey thanked Lou Sanders, Dave Phelps and ATPA for hosting this meeting of Working Group #2 (WG2) of the Rail Transit Vehicle Interface Standards Committee (RTVISC).
1.2 Review of Previous WG2 Meeting Minutes
The minutes of the previous WG2 meeting held on November 2, 2000 were reviewed and accepted as written.
1.3 Status of Other CBTC-Related Standards
Initiatives
1.3.1 Environmental Standards
for CBTC Wayside Equipment
Harold Gillen is chairing a new Working Group to develop environmental standards for wayside electronic equipment, including wayside CBTC equipment.
Scope and Purpose for this proposed standard has been approved.
Anyone interested in participating in this Working Group should contact Harold directly.
1.3.2 Future Updates to 1474.1
The existing IEEE Std. 1474.1-1999 will be updated in the future to include an expansion of the functional requirements in paragraph 6.1.15: "Highway grade crossing warning". The existing IEEE Std. 1474.1-1999 will also be updated in the future to include CBTC performance and functional requirements for train operations without crews. Planning for these and other updates to IEEE Std. 1474.1-1999 will be initiated at a WG2 meeting later this year.
1.4 Railway Age/Parsons Transportation Group
International CBTC Conference
Alan Rumsey advised that the 4th International Conference on Communications based Train Control, sponsored by Railway Age and Parsons Transportation Group, will be held in Washington D.C. on May 8/9, 2001. Further details can be obtained from the Railway Age website (www.railwayage.com).
