Dear Sir:

        This is to confirm our discussions of Article IV,
Section 2(b) of the Crew Consist Agreement of September 15,
1980.

        It was agreed that when the Conductors' and Brakemen's
Extra Boards are exhausted and there are no available protected
road brakemen holding blankable road brakemen positions at that
location, the Carrier shall use a must-fill conductor and/or
brakeman (as needed) who is rested and available in accordance
with existing work rules.

        Once a trainman is so used in emergency service and
returns to his/her home terminal, he/she will not be required to
be available or accept call for additional service while his/her
regular assignment is at work. Once his/her regular assignment
is back at the home terminal, a new cycle will begin.

        If the foregoing correctly sets forth the under-
standing reached in conference, please affix your signature in
the space provided below. 

Yours truly,

L. A. Lambert
Director Labor Relations

AGREED:
