Engineers in pool freight and in unassigned service held at other than home terminal will be paid continuous time for all time so held after the expiration of sixteen hours from the time relieved from previous duty, at the regular rate per hour paid them for the last service performed. If held sixteen hours after the expiration of the first twenty-four hour period, they will be paid continuous time for the time so held during the next succeeding eight hours, or until the end of the second twenty-four hour period, and similarly for each twenty-four hour period thereafter.

Should an engineer be called for service or ordered to deadhead after pay begins, the held-away-from home terminal time shall cease at the time pay begins for such service or, when deadheading, at the time the train leaves the terminal, except that in no event shall there be duplication of payment for deadhead time and held-away-from home terminal time.

Payments accruing under this rule shall be paid for separate and apart from pay for the subsequent service or deadheading.

For the purpose of applying this rule, the railroad will designate a home terminal for each crew in pool freight and in unassigned service.
