Dear Betty Jo:

As requested by Betty Jo Christian in her memorandum of July 28, 1994, I am
enclosing our estimates of Reproduction Cost New Less Depreciation (RCNLD) for
NCRR properties for each of the six scenarios listed in her request. The results
of our analysis are summarized in the table immediately below and the
assumptions regarding unit reproduction costs, depreciation rates, and other key
valuation factors are detailed in the enclosed exhibits.

                           Summary of RCNLD Estimates

There are several cautions that need to be mentioned with respect to these
estimates. First, while these estimates represent a further refinement of our
initial RCNLD work in our September 1993 Preliminary Report, they are still
based on a "desktop" analysis of track charts, aerial photographs, and the like
and do not include any physical inspection on our part of any of the NCRR
properties.

Second, while we believe the estimates to be reasonable for purposes of
counsel's assessment of the RCNLD approach, additional work would have to be
conducted prior to submission of RCNLD values in any proceeding before the ICC.
Such work would include site-specific inspections of track, bridge and grading
condition, and site-particular values for real estate. These more detailed
on-site sample observations would be used to further refine the desktop
estimates and provide a basis for standing reply and cross-examination efforts
in any proceeding.

Finally, you will note per Exhibit 5 in the enclosure that approximately $38
million of the nearly $50 million in RCNLD value for yards and shops is
attributable to Linwood Yard. This $38 million is the estimated RCNLD for the
yard as a whole. To the extent that the NCRR-related portion of the yard is
deemed to be only a small portion of the total facility, most of this value
would drop from the scenario 6 value.

Per Scott Saylor's request, in his July 28, 1994 memorandum, we have also
separately estimated (Exhibit 8) the RCNLD value of the equipment at issue
between NCRR and NS to be $30 million. This value presumes replacement of early
20th Century locomotives and cars with their modern-era equivalent at the
depreciated rates shown in the exhibit.

We have not taken into account in this analysis the costs to maintain the rail
track and related rail facilities on NCRR, leaving this issue open for possible
future review.

Sincerely,


/s/ Timothy R. Murphy

o land values are scaled downward from the values in 3. for 200 ft ROW assuming
a minimum constant of $50,000 per mile. For example, the 200 ft ROW value for
Charlotte-Greensboro is first reduced by $50,000 per mile ($4.55 million) and
then multiplied by 25%, reflecting the 50 ft vs 200 ft ROW. The resulting amount
is then added to $4.55 million.
