from and after such Interest Payment Date or Maturity Date, as the case may

         For so long as any Notes issued pursuant to this Ninth Supplemental

Subsidiary to, create, assume, incur or suffer to exist any mortgage, pledge,
lien, encumbrance, charge or security interest of any kind, other than a
Purchase Money Lien, upon any stock or indebtedness, whether owned on the date
any Notes are first issued or thereafter acquired, of any Principal
Subsidiary, to secure any Obligation (other than the Notes) of the
Corporation, any Subsidiary or any other person, without in any such case
making effective provision whereby all of the outstanding Notes shall be
directly secured equally and ratably with such Obligation. This Section 301
shall not (i) apply to any mortgage, pledge, lien, encumbrance, charge or
security interest on any stock or indebtedness of a corporation existing at
the time such corporation becomes a Subsidiary, (ii) restrict any other
property of the Corporation or its Subsidiaries, or (iii) restrict the sale by

Subsidiary.

         Section 302 Limitations on Funded Debt.

         For so long as any Notes issued pursuant to this Ninth Supplemental
Indenture are Outstanding, the Corporation will not permit any Restricted
Subsidiary to incur, issue, guarantee or create any Funded Debt unless, after
giving effect thereto, the sum of the aggregate amount of all outstanding
Funded Debt of the Restricted Subsidiaries would not exceed an amount equal to
15% of Consolidated Net Tangible Assets.

         This Section 302 shall not apply to, and there shall be excluded from
Funded Debt in any computation hereto, Funded Debt secured by: (i) Liens on
real or physical property of any corporation existing at the time such
corporation becomes a Subsidiary; (ii) Liens on real or physical property
existing at the time of acquisition thereof incurred within 180 days of the
time of acquisition thereof (including, without limitation, acquisition
through merger or consolidation) by the Corporation or any Restricted
Subsidiary; (iii) Liens on real or physical property thereafter acquired (or
constructed) by the Corporation or any Restricted Subsidiary and created prior
to, at the time of, or within 270 days after such acquisition (including,
without limitation, acquisition through merger or consolidation) (or the
completion of such construction or commencement of commercial operation of
such property, whichever is later) to secure or provide for the payment of all
or any part of the purchase price (or the construction price) thereof; (iv)
Liens in favor of the Corporation or any Restricted Subsidiary; (v) Liens in
favor of the United States of America, any State thereof or the District of
Columbia, or any agency, department or other instrumentality thereof, to
secure partial, progress, advance or other payments pursuant to any contract
or provisions of any statute, (vi) Liens incurred or assumed in connection
with the issuance of revenue bonds the interest on which is exempt from
Federal Income taxation pursuant to Section 103(b) of the Internal Revenue
Code of 1954, as amended; (vii) Liens securing the performance of any contract
or undertaking not directly or indirectly in connection with the borrowing of
money, the obtaining of advances or credit or the securing of Funded Debt, if
made and continuing in the ordinary course of business; (viii) Liens incurred
(no matter when created) in connection with the Corporation's or a Restricted
Subsidiary's engaging in leveraged or single-investor lease transaction;
provided, however, that the instrument creating or evidencing any borrowings
secured by such Lien will provide that such borrowings are payable solely out
of the income and proceeds of the property subject to such Lien and are not a
general obligation of the Corporation or such Restricted Subsidiary; (ix)
Liens under workers' compensation laws, unemployment insurance laws or similar
legislation, or good faith deposits in connection with bids, tenders,
contracts or deposits to secure public or statutory obligations of the
Corporation or any Restricted Subsidiary, or deposits of cash or obligations
of the United States of America to secure surety, repletion and appeal bonds
to which the Corporation or any Restricted Subsidiary is a party or in lieu of
such bonds, or pledges or deposits for similar purposes in the ordinary course
of business, or Liens imposed by law, such as laborers' or other employees',
carriers', warehousemen's, mechanics', materialmen's and vendors' Liens and
Liens arising out of judgments or awards against the Corporation or any
Restricted Subsidiary with respect to which the Corporation or such Restricted
Subsidiary at the time shall be prosecuting an appeal or proceedings for
review and with respect to which it shall have secured a stay of execution
pending such appeal or proceedings for review, or Liens for taxes not yet
subject to penalties for nonpayment or the amount or validity of which is
being in good faith contested by appropriate proceedings by the Corporation or
any Restricted Subsidiary, as the case may be, or minor survey exceptions,
minor encumbrances, easement or reservations of, or rights of others for,
rights of-way, sewers, electric lines, telegraph and telephone lines and other
similar purposes, or zoning or other restrictions or Liens on the use of real
properties which Liens, exceptions, encumbrances, easements, reservations,
rights and restrictions do not, in the opinion of the Corporation, in the
aggregate materially detract from the value of said properties or materially
impair their use in the operation of the business of the Corporation and its
Restricted Subsidiaries; (x) Liens incurred to finance construction,
alteration or repair of any real or physical property and improvements thereto
prior to or within 270 days after completion of such construction, alteration
or repair; (xi) Liens incurred (no matter when created) in connection with a
Securitization Transaction; (xii) Liens on property (or any Receivable arising
in connection with the lease thereof) acquired by the Corporation or a

banks (in the aggregate, not exceeding $50 million), in accordance with
customary banking practice, in connection with the providing by the
Corporation or a Restricted Subsidiary of financial accommodations to any
Person in the ordinary course of business; or (xiv) any extension, renewal,
refunding or replacement of the foregoing.

together with the accrued interest to the Redemption Date; provided, however,
that interest installments due on an Interest Payment Date which is on or
prior to the Redemption Date will be payable to those Holders who are Holders
of record of the Notes (or one or more predecessor Notes) as of the close of
business on the regular record date preceding such Interest Payment Date.

         (b) If the Notes are only partially redeemed pursuant to this Section

         This Note is a Global Note within the meaning of the Base Indenture
hereinafter referred to and is registered in the name of a Depositary or a
nominee of a Depositary. This Note is exchangeable for Notes registered in the
name of a person other than the Depositary or its nominee only in the limited
circumstances described in the Base Indenture, and no transfer of this Note
(other than a transfer of this Note as a whole by the Depositary to a nominee
of the Depositary or by a nominee of the Depositary to the Depositary or
another nominee of the Depositary) may be registered except in limited
circumstances.

         Unless this Note is presented by an authorized representative of The
Depository Trust Company, a New York Corporation ("DTC"), to the issuer or its
agent for registration of transfer, exchange or payment, and any Note issued
is registered in the name of Cede & Co. or in such other name as is requested
by an authorized representative of DTC (and any payment is made to Cede & Co.
or to such other entity as is requested by an authorized representative of
DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO
ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co.,
has an interest herein.

                                     NOTE
                              DUE MARCH 15, 2105

         NORFOLK SOUTHERN CORPORATION, a corporation organized under the laws
of the Commonwealth of Virginia (herein called the "Corporation", which term
includes any successor corporation under the Base Indenture hereinafter
referred to), for value received, hereby promises to pay to
___________________, or registered assigns, the principal sum of
________________ Dollars ($________) on March 15, 2105 and to pay interest
thereon from March 11, 2005 or from the most recent interest payment date to
which interest has been paid or duly provided for, semi-annually in arrears on
March 15 and September 15 of each year, commencing September 15, 2005, at a
rate of 6% per annum until the principal hereof is paid or made available for
payment, and on any overdue principal and premium, if any, at a rate of 6% per
annum and (without duplication and to the extent that payment of such interest
is enforceable under applicable law) on any overdue installment of interest at
a rate of 6% per annum compounded semi-annually. The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date (as defined
below) shall be calculated as provided in the Base Indenture. In the event
that any date on which interest is payable on this Note is not a Business Day,
then payment of interest payable on such date will be made on the next
succeeding day that is a Business Day, with the same force and effect as if
made on such date and no interest shall accrue on the amount so payable from
the period from and after such Interest Payment Date or Maturity Date, as the
case may be (each date on which interest is actually payable, an "Interest
Payment Date"). The interest installment so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in the Base
Indenture, be paid to the Person in whose name this Note (or one or more
Predecessor Security, as defined in said Base Indenture) is registered at the
close of business on the regular record date for such interest installment,
which shall be the close of business on the March 1 and September 1 next
preceding such Interest Payment Date. Any such interest installment not
punctually paid or duly provided for shall forthwith cease to be payable to
the registered Holders on such regular record date and may be paid to the
Person in whose name this Note (or one or more Predecessor Security) is
registered at the close of business on a special record date to be fixed by
the Trustee for the payment of such defaulted interest, notice whereof shall
be given to the registered Holders of Notes not less than 10 days prior to
such special record date, or may be paid at any time in any other lawful
manner not inconsistent with the requirements of any securities exchange on
which this Note may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Base Indenture. The principal of
(and premium, if any) and the interest on this Note shall be payable at the
office or agency of the Trustee maintained for that purpose in any coin or
currency of the United States of America that at the time of payment is legal
tender for payment of public and private debts; provided, however, that
payment of interest may be made, at the option of the Corporation and upon
prior notice to the Trustee, by check mailed to the registered Holder at such
address as shall appear in the Security Register or by wire transfer to an
account designated by a Holder in writing not less than 10 days prior to the
date of payment.

         The indebtedness evidenced by this Note is, to the extent provided in
the Base Indenture, equal in right of payment with all other unsecured and
unsubordinated indebtedness of the Corporation, and this Note is issued
subject to the provisions of the Base Indenture, the First Supplemental
Indenture, the Second Supplemental Indenture, the Third Supplemental
Indenture, the Fourth Supplemental Indenture, the Fifth Supplemental
Indenture, the Sixth Supplemental Indenture, the Seventh Supplemental
Indenture, the Eighth Supplemental Indenture and the Ninth Supplemental
Indenture with respect thereto. Each Holder of this Note, by accepting the
same, agrees to and shall be bound by such provisions, and authorizes and
directs the Trustee on his or her behalf to be bound by such provisions. Each
Holder hereof, by his or her acceptance hereof, hereby waives all notice of
the acceptance of the provisions contained herein and in the Base Indenture
the First Supplemental Indenture, the Second Supplemental Indenture, the Third
Supplemental Indenture, the Fourth Supplemental Indenture, the Fifth
Supplemental Indenture, the Sixth Supplemental Indenture, the Seventh
Supplemental Indenture, the Eighth Supplemental Indenture and the Ninth
Supplemental Indenture by each Holder of unsecured and unsubordinated
indebtedness of the Corporation, whether now outstanding or hereafter
incurred, and waives reliance by each such Holder or creditor upon said
provisions.

         This Note shall not be entitled to any benefit under the Base
Indenture the First Supplemental Indenture, the Second Supplemental Indenture,
the Third Supplemental Indenture, the Fourth Supplemental Indenture, the Fifth
Supplemental Indenture, the Sixth Supplemental Indenture, the Seventh
Supplemental Indenture, the Eighth Supplemental Indenture or the Ninth
Supplemental Indenture hereinafter referred to, or be valid or become
obligatory for any purpose until the Certificate of Authentication hereon
shall have been signed by or on behalf of the Trustee.

         The provisions of this Note are continued on the reverse side hereof
and such continued provisions shall for all purposes have the same effect as
though fully set forth at this place.



         IN WITNESS WHEREOF, the Corporation has caused this instrument to be
executed.

                           (FORM OF REVERSE OF NOTE)

         This Note is one of a duly authorized series of securities of the
Corporation (herein sometimes referred to as the "Security"), issued or to be
issued in one or more series under and pursuant to an Indenture dated as of
January 15, 1991 (the "Base Indenture"), duly executed and delivered between
the Corporation and U.S. Bank Trust National Association, formerly known as
First Trust of New York National Association, as successor trustee (the
"Trustee"), as supplemented by the First Supplemental Indenture, dated as of
May 19, 1997 (the "First Supplemental Indenture"), between the Corporation and
the Trustee, the Second Supplemental Indenture, dated as of April 26, 1999
(the "Second Supplemental Indenture") between the Corporation and the Trustee,
the Third Supplemental Indenture, dated as of May 23, 2000 (the "Third
Supplemental Indenture") between the Corporation and the Trustee, the Fourth
Supplemental Indenture, dated as of February 6, 2001 (the "Fourth Supplemental
Indenture") between the Corporation and the Trustee, the Fifth Supplemental
Indenture, dated as of July 5, 2001 (the "Fifth Supplemental Indenture")
between the Corporation and the Trustee, the Sixth Supplemental Indenture
dated as of April 30, 2002 (the "Sixth Supplemental Indenture") between the
Corporation and the Trustee, the Seventh Supplemental Indenture, dated as of
April 30, 2002 (the "Seventh Supplemental Indenture") between the Corporation
and the Trustee, the Eighth Supplemental Indenture dated as of September 17,
2004 (the "Eighth Supplemental Indenture") between the Corporation and the
Trustee and the Ninth Supplemental Indenture, dated as of March 11, 2005 (the
"Ninth Supplemental Indenture"), between the Corporation and the Trustee, to
which Base Indenture, First Supplemental Indenture, Second Supplemental
Indenture, Third Supplemental Indenture, Fourth Supplemental Indenture, Fifth
Supplemental Indenture, Sixth Supplemental Indenture, Seventh Supplemental
Indenture, Eighth Supplemental Indenture and Ninth Supplemental Indenture
reference is hereby made for a description of the rights, limitations of
rights, obligations, duties and immunities thereunder of the Trustee, the
Corporation and the Holders of the Security. By the terms of the Base
Indenture, the Securities are issuable in series that may vary as to amount,
date of maturity, rate of interest and in other respects as provided in the
Base Indenture. This Security is the series designated on the face hereof (the
"Notes") and is limited in aggregate principal amount as specified in said
Ninth Supplemental Indenture.

         This Note may be redeemed in whole at any time or in part from time
to time, at the Corporation's option, at a redemption price equal to the
greater of (1) 100% of its principal amount or (2) the sum of the present
values of the remaining scheduled payments of principal and interest on the
Note to be redeemed discounted to the date of redemption on a semi-annual
basis (assuming a 360-day year consisting of twelve 30-day months) at the
applicable Treasury Yield, as defined in the Ninth Supplemental Indenture,
plus 20 basis points for the Note, plus, accrued and unpaid interest on the
principal amount being redeemed to the Redemption Date.

         In case an Event of Default, as defined in the Base Indenture, shall
have occurred and be continuing, the principal of all of the Notes may be
declared due and payable, in the manner, with the effect and subject to the
conditions provided in the Base Indenture.

         The Base Indenture contains provisions permitting the Corporation and
the Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Outstanding Security of each series affected
to execute supplemental indentures for the purpose of adding any provisions to
the Base Indenture or of modifying in any manner the rights of the Holders of
the Security; provided, however, that no such supplemental indenture shall (i)
change the Stated Maturity of the principal of, or any installment of
principal of or interest on, any Security, or reduce the principal amount
thereof or any premium payable upon the redemption thereof or the rate of
interest thereon, or to reduce the amount of principal of an Original Issue
Discount Security that would be due and payable upon a declaration of
acceleration of the Maturity thereof pursuant to Section 502 of the Base
Indenture, or change any Place of Payment where, or the coin or currency in
which, any Security (or premium, if any, thereon) or the interest thereon is
payable, or impair the right to institute suit for the enforcement of any such
payment on or after the Stated Maturity thereof (or, in the case of
redemption, on or after the Redemption Date); or (ii) reduce the percentage in
principal amount of the Outstanding Security of any series, the Holders of
which are required to consent to any such supplemental indenture or to waive
certain defaults thereunder and their consequences provided for in the Base
Indenture; or (iii) modify any of the provisions of the Base Indenture
relating to supplemental indentures that require the consent of the Holders,
or the waiver of past defaults or the waiver of certain covenants, except to
increase any such percentage or to provide that certain other provisions of
the Base Indenture cannot be modified or waived, without the consent of the
Holders of each Outstanding Security affected thereby. The Base Indenture also
contains provisions permitting the Holders of not less than a majority in
principal amount of the Outstanding Security of any series affected thereby,
on behalf of all of the Holders of the Security of such series, to waive any
past Default under the Base Indenture, and its consequences, except a Default
in the payment of the principal of, premium, if any, or interest on any
Security of such series or a Default in respect of a covenant or provision of
the Base Indenture which cannot be modified or amended without the consent of
the Holder of each Outstanding Security of such series affected. Any such
consent or waiver by the registered Holder of this Note (unless revoked as
provided in the Base Indenture) shall be conclusive and binding upon such
Holder and upon all future Holders and owners of this Note and of any Note
issued in exchange therefor or in place hereof (whether by registration of
transfer or otherwise), irrespective of whether or not any notation of such
consent or waiver is made upon this Note.

         No reference herein to the Base Indenture, the First Supplemental
Indenture, the Second Supplemental Indenture, the Third Supplemental
Indenture, the Fourth Supplemental Indenture, the Fifth Supplemental
Indenture, the Sixth Supplemental Indenture, the Seventh Supplemental
Indenture, the Eighth Supplemental Indenture or the Ninth Supplemental
Indenture and no provision of this Note or of the Base Indenture, the First
Supplemental Indenture, the Second Supplemental Indenture, the Third
Supplemental Indenture, the Fourth Supplemental Indenture, the Fifth
Supplemental Indenture, the Sixth Supplemental Indenture, the Seventh
Supplemental Indenture, the Eighth Supplemental Indenture or the Ninth
Supplemental Indenture shall alter or impair the obligation of the
Corporation, which is absolute and unconditional, to pay the principal of and
premium, if any, and interest on this Note at the time and place and at the
rate and in the money herein prescribed.

         As provided in the Base Indenture and subject to certain limitations
therein set forth, this Note is transferable by the registered Holder hereof
on the Security Register of the Corporation, upon surrender of this Note for
registration of transfer at the office or agency of the Trustee in New York,
New York duly endorsed by the registered Holder hereof or accompanied by a
written instrument or instruments of transfer in form satisfactory to the
Corporation and the Security Registrar duly executed by the registered Holder
hereof or his attorney duly authorized in writing, and thereupon one or more
new Notes of this series of authorized denominations and for the same
aggregate principal amount will be issued to the designated transferee or
transferees.

         No service charge will be made for any such transfer, but the
Corporation may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto.

         Prior to due presentment of this Note for registration of transfer of
this Note, the Corporation, the Trustee, and any agent of the Corporation or
the Trustee may treat the registered Holder hereof as the owner hereof
(whether or not this Note shall be overdue) and neither the Corporation, the
Trustee nor any such agent shall be affected by notice to the contrary.

         No recourse shall be had for the payment of the principal of or the
interest on this Note, or for any claim based hereon, or otherwise in respect
hereof, or based on or in respect of the Base Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Corporation or of any predecessor or successor corporation,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the
issuance hereof, expressly waived and released.

         The Notes are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. This Global Note is
exchangeable for Notes in definitive form only under certain limited
circumstances set forth in the Base Indenture. Notes so issued are issuable
only in registered form without coupons in denominations of $1,000 and any
integral multiple thereof. As provided in the Base Indenture and subject to
certain limitations herein and therein set forth, Notes of this series so
issued are exchangeable for a like aggregate principal amount of Notes of a
different authorized denomination, as requested by the Holder surrendering the
same.

         All terms used in this Note that are defined in the Base Indenture,
the First Supplemental Indenture, the Second Supplemental Indenture, the Third
Supplemental Indenture, the Fourth Supplemental Indenture, the Fifth
Supplemental Indenture, the Sixth Supplemental Indenture, the Seventh
Supplemental Indenture, the Eighth Supplemental Indenture or the Ninth
Supplemental Indenture shall have the meanings assigned to them therein.

         THE BASE INDENTURE, THE FIRST SUPPLEMENTAL INDENTURE, THE SECOND
SUPPLEMENTAL INDENTURE, THE THIRD SUPPLEMENTAL INDENTURE, THE FOURTH
SUPPLEMENTAL INDENTURE, THE FIFTH SUPPLEMENTAL INDENTURE, THE SIXTH
SUPPLEMENTAL INDENTURE, THE SEVENTH SUPPLEMENTAL INDENTURE, THE EIGHTH
SUPPLEMENTAL INDENTURE, THE NINTH SUPPLEMENTAL INDENTURE AND THE NOTES SHALL
BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW
YORK.
