(2) If individual locomotive units or classes or locomotive units are used interchangeably (common) in road-freight (including train-switching), road passenger (including train switching), yard-freight or yard-passenger service, separate the heavy shop repairs between these services on the basis of run-out unit miles of individual locomotive units or classes of locomotive units since the previous shopping; and separate the cost of running repairs between such services on the basis of the miles run by the individual locomotive unit or class of locomotive unit in each service during the accounting period for which the separation is being made.
