(b) The employee required to make such trip or trips as an engineer in accordance with the provisions of paragraph (a) hereof shall be paid therefor on the same basis as the engineer called for the service to handle the train. If necessary to deadhead to make such trip or trips such dead-heading will be paid for under existing rules.
