RULE 70. ATTENDING COURT. Engineers attending court or other business (other than attending investigations) on behalf of the Company will be paid as follows, together with necessary expenses:
(a) Engineers in the established pool or on assigned runs will receive what they would have earned had they remained on assignment, and if used on layover days will receive a minimum day's pay.
(b) Extra engineers will be allowed one day's pay of 100 miles at the minimum freight rate applicable to the district to which assigned for each day held.
(e) If an extra engineer is held from a regular assignment, he will be entitled to what he would have earned on the assignment for such time as he is eligible to hold it. In case the extra man could not hold a regular assignment during the full period of time he is on Company business, he would, therefore, be entitled to only a minimum day's pay at minimum freight rate applicable to the district to which assigned for the days on which he could not hold a regular assignment.
(d) Any fee or mileage accruing will be assigned to the railroad.
