RULE 9. MORE THAN ONE CLASS OF ROAD SERVICE. Road engineers employed in any class of road service may be required to perform two or more classes of road service in a day or trip subject to the following terms and conditions:

A. Payment

1. Except as qualified by A-2 below, payment for the entire service shall be made at the highest rate applicable to any class of service performed, the overtime basis for the rate paid to apply for the entire trip. Not less than a minimum day will be paid for the combined service.

When two or more locomotives of different weight on drivers are used during a trip or day's work, the highest rate applicable to any locomotive used shall be paid for the entire day or trip.

2. Road engineers in through freight and passenger service only shall receive full payment for the regular day or trip based on miles or hours applicable to the regular day or trip plus extra compensation on a 1 minute basis for all additional time required in the other class of road service.

The rate paid both for the regular trip and for the additional time shall be the highest rate applicable to any class of service performed during the entire day or trip.

When two or more locomotives of different weight on drivers are used during a trip or day's work, the highest rate applicable to any locomotive shall be paid for the entire day or trip.

Overtime rate shall apply to the extra compensation only to the extent that the additional service results in overtime for the entire day or trip or adds to overtime otherwise payable for hours required for the regular trip.
