1152.33—Apportionment rules for the assignment of expenses to on-branch costs.

The accounts specified under § 1152.32 (a), (b), (c), and (d) as having an assignment basis other than “Actual” shall be apportioned according to the rules contained in this section.
(1) Multiply the total amounts in these accounts (from the R-1 Annual Report, Schedule 410) by 69 percent, which is the ratio of train-mile and running expenses;
(2) Divide the amount in paragraph (c)(1)(i)(A)(1) of this section by the total system loaded and empty car-miles; and
(3) Multiply the car-mile unit cost factor from paragraph (c)(1)(i)(A)(2) of this section by the on-branch car-miles (loaded and empty).
(1) Multiply the total amounts in these accounts by 31 percent, which is the ratio of terminal expenses;
(2) Divide the amount in paragraph (c)(1)(i)(B)(1) of this section by the total system carloads; and
(3) Multiply the carload unit cost factor from paragraph (c)(1)(i)(B)(2) of this section by the on-branch carloads.
(ii) All accounts designated xx-31-67 shall be assigned to the branch in accordance with the following procedure. The dollar amounts used in the determination of locomotive fuel costs shall be based on data contained in the most recent publication issued by the General Managers Association (GMA) relating to the rental of locomotives. The total number of locomotive unit hours incurred by the locomotive(s) shall then be categorized according to the applicable GMA horsepower classification group. The fuel cost is derived from the Repairs and Supplies Expenses element of the locomotive rental rates published by the GMA. The fuel cost per locomotive unit hour shall be determined for each GMA horsepower classification group by multiplying the latest GMA fuel cost percentage by the Repairs and Supplies Expense per hour included in each group. The fuel cost update ratio is determined by using the indices for fuel from the Association of American Railroad's (AAR's) Railroad Cost Recovery Index (RCR). The indices shall be taken from the district to which the railroad is assigned by the Board. The index for the current period is divided by the index of the period representative of the GMA publication to develop the fuel update ratio. The fuel cost per locomotive unit hour developed for each GMA horsepower group shall be multiplied by the fuel update ratio to determine the fuel cost per locomotive hour for each horsepower group. The updated fuel cost per locomotive unit hour for each applicable GMA group shall be multiplied by the number of locomotive unit hours incurred in serving the branch by locomotives of that GMA horsepower classification group. The total cost developed under this procedure for each horsepower classification shall be the locomotive fuel cost assignable to the branch line.
