(a) Mileage rates of pay for miles run in excess of the number of miles comprising a basic day will not be subject to general, cost-of-living, or other forms of wage increases.

    (b) Mileage rates of pay, as defined above, applicable to interdivisional, interseniority district, intradivisional and/or intraseniority district service runs now existing or to be established in the future shall not exceed the applicable rates as of October 31, 1985. Such rates shall be exempted from wage increases as provided in Section Ka) of this Article. Car scale additives and weight-on-drivers additives will apply to mileage rates calculated in accordance with this provision.

    (a) The miles encompassed in the basic day and the divisor used to determine when overtime begins in through freight and through passenger service will be changed as provided below:

Effective Date     Through Freight Service     Through Passenger Service
of Change
                Miles in Basic    Overtime    Miles in Basic    Overtime
                    Day           Divisor        Day*           Divisor

July 29, 1991     114             14.25         171-114         22.8

January 1, 1992   118             14.75         177-118         23.6

January 1, 1993   122             15.25         183-122         24.4

January 1, 1994   126             15.75         189-126         25.2

January 1, 1995   130             16.25         195-130         26.0

* The higher mileage numbers apply to conductors and brakemen and the lower mileage numbers apply to engineers and firemen.

    (b) Mileage rates will be paid only for miles run in excess of the minimum number specified in (a) above.

    (c) The number of hours that must lapse before overtime begins on a trip in through freight or through passenger service is calculated by dividing the miles of the trip or the number of miles encompassed in a basic day in that class of service, whichever is greater, by the appropriate overtime divisor. Thus, effective July 29, 1991, overtime on a trip in through freight service of 125 miles will begin after 8 hours and 46 minutes (125/14.25 s 8.77 hours). In through freight service, overtime will not be paid prior to the completion of 8 hours of service.

    When employees in through freight service become entitled to the local rate of pay under applicable conversion rules, the daily local freight differential (56 cents for conductors and engineers and 43 cents for brakemen and firemen under national agreements) will be added to their basic daily rates and the combined rate will be used as the basis for calculating hourly rates, including overtime. The local freight mileage differential (.56 cents per mile for conductors and engineers and .43 cents for brakemen and firemen under national agreements) will be added to the through freight mileage rates, and miles in excess of the number encompassed in the basic day in through freight service will be paid at the combined rate.

    (a) Duplicate time payments, including arbitraries and special allowances that are expressed in time or miles or fixed amounts of money, shall not apply to employees whose seniority in train or engine service is established on or after November 1, 1985.

    (b) Duplicate time payments, including arbitraries and special allowances that are expressed in time or miles or fixed amounts of money, not previously eliminated, shall not be subject to general, cost-of-living or other forms of wage increases.

    In any class of service or job classification, rates of pay, additives, and other applicable elements of compensation for an employee whose seniority in train or engine service is established on or after November 1, 1985, will be 75X of the rate for present employees and will increase in increments of 5 percentage points for each year of active service until the new employee's rate is equal to that of present employees. A year of active service shall consist of a period of 365 calendar days in which the employee performs a total of 80 or more tours of duty.
