Rolling stock.

(b) Such rolling stock as is primarily located in the District of Columbia shall be reported and taxed at its full and true value on the last day of the calendar year preceding the tax date.

(c) Such rolling stock as is not primarily located in the District of Columbia shall be reported and taxed in the manner following:

(1) Every railroad company operating rolling stock over or upon the line or lines of any railroad or terminal company in the District shall report to the Mayor of the District of Columbia the various classes of such rolling stock so operated by such company whether owned by it or any other railroad company; the number of miles traveled by each class of such rolling stock within the District during the calendar year next preceding the tax date; the total number of miles traveled by each class of such rolling stock on all lines over which such company operates during the calendar year next preceding the tax date; the total full and true value of each class of such rolling stock owned by such company on the last day of the calendar year next preceding the tax date; and such other facts and information as the Mayor may require. The taxable portion of the rolling stock of each such company shall be determined by applying the mileage traveled in the District by the various classes of such rolling stock operated in the District by such company to the total mileage traveled by the various classes of such rolling stock on all lines over which such company operates, and the tax shall be assessed on that portion of such rolling stock owned by such company on the last day of the calendar year next preceding the tax date. The mileage and value of the rolling stock owned by such company which is permanently located outside of the District of Columbia shall not be included in the computation of such assessment;

The taxable portion of the value of the cars owned by any such company and used within the District shall be determined by applying to such value the ratio between the mileage traveled by such cars in the District and the total mileage traveled by such cars within and without the District;

(3)

(A) Every car company, mercantile company, corporation or individual (other than railroad, parlor-car, and sleeping-car companies described in paragraphs (1) and (2) of this subsection) owning or leasing any stock cars, furniture cars, fruit cars, refrigerator cars, meat cars, oil cars, tank cars, or other similar cars, which are run over or upon the line or lines of any railroad or terminal company in the District of Columbia, shall furnish to the Mayor of the District of Columbia, on forms prescribed by the Mayor, a true, full, and accurate statement, verified by the affidavit of the officer or person making the same, showing the aggregate number of miles made by their several cars over or upon the several lines of railroad within the District of Columbia during the calendar year next preceding the tax date; the average number of miles traveled per day within the District of Columbia by the cars covered by the statement in the ordinary course of business during the year; and such other pertinent facts and information as the Mayor may require.

(C) It shall be the duty of the Mayor to ascertain from the best and most reliable information that can be obtained and from said statements the number of cars required to make the total mileage of each such car company, mercantile company, corporation, or individual within the District of Columbia during the period aforesaid, and to ascertain and fix the valuation upon each particular class of such cars, and the number so ascertained to be required to make the total mileage within the District of Columbia of the cars of each such car company, mercantile company, corporation, or individual within said period shall be assessed against the respective car companies, mercantile companies, corporations, or individuals. The valuation thus obtained shall be the full and true value and shall be the taxable portion of the cars owned by any such car company, mercantile company, corporation, or individual and used within the District of Columbia.
