    (a) The North American Industry Classification System (NAICS) has replaced
the Standard Industrial Classification (SIC) system.
    NF=No applicable RSE row/column factor.
    * Estimate less than 0.5.
    W=Withheld to avoid disclosing data for individual establishments.
    Q=Withheld because Relative Standard Error is greater than 50 percent.
    NA=Not available.
    Notes:  To obtain the RSE percentage for any table cell, multiply the cell's
corresponding RSE column and RSE row factors.   Totals may not equal sum of
components because of independent rounding.
Operating ratios were calculated using the estimates of fuel consumption
reported in Table N3.2.
