(35 ILCS 200/11-80)
    Sec. 11-80. Assessment procedure for railroad companies. In assessing the taxable property of any railroad company, the Department shall first determine 33 1/3% of the fair cash value of all the property of any railroad company as a unit, but shall make due allowance for any non-carrier real estate and all personalty.
    The Department shall take into consideration the actual or market value of the shares of stock outstanding, the actual or market value of all bonds outstanding and all other indebtedness as is applicable, for operating the road. In determining the market value of the stock or indebtedness the Department shall consider quotations for the 5 years preceding the assessment date; the net earnings of the company during the 5 calendar years preceding the assessment date; and such other information as the Department may consider as bearing on the fair cash value of the property. The valuation by the Department shall include capital stock and all other property of railroad companies, except non-carrier real estate. The above facts shall not be conclusive upon the Department in determining 33 1/3% of the fair cash value of the property of a railroad company.
    The Department shall determine the equalized assessed value of the taxable property of every railroad company by applying to its determination of 33 1/3% of the fair cash value of the property an equalization factor equal to the statewide average ratio of the equalized assessed value of locally assessed property to 33 1/3% of the fair cash value of such locally assessed property.
    The Department shall assess the value of all operating property acquired by a railroad company or its wholly-owned subsidiary by trade with a municipality, which is situated in a state contiguous to Illinois, at no greater value than the value of the operating property traded to the municipality for the property by the railroad company. The value shall be that value established for the year immediately preceding the calendar year of the trade. The assessment shall not increase, but may decrease, during the 10 years following the calendar year of the trade.
