             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



The Participants and Plan Administrator
MidSouth Rail Union 401(k) Retirement Savings Plan:


We have audited the accompanying statements of net assets available for benefits
of the  MidSouth  Rail Union  401(k)  Retirement  Savings  Plan (the Plan) as of
December 31, 2003 and 2002, and the related  statements of changes in net assets
available for benefits for the years then ended. These financial  statements are
the responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance  with the standards of the Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the net assets available for benefits of the Plan as of
December 31, 2003 and 2002, and the changes in net assets available for benefits
for the years then ended,  in conformity with  accounting  principles  generally
accepted in the United States of America.

Our audits  were  performed  for the  purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) is presented for the purpose of additional analysis and is not a
required  part  of  the  basic  financial   statements,   but  is  supplementary
information  required by the  Department  of Labor's Rules and  Regulations  for
Reporting and Disclosure  under the Employee  Retirement  Income Security Act of
1974. This supplemental schedule is the responsibility of the Plan's management.
The supplemental  schedule has been subjected to the auditing procedures applied
in the audits of the basic financial  statements and, in our opinion,  is fairly
stated, in all material respects,  in relation to the basic financial statements
taken as a whole.

                          Notes to Financial Statements

                           December 31, 2003 and 2002



(1)  DESCRIPTION OF THE PLAN

     The  following  description  of the MidSouth  Rail Union 401(k)  Retirement
     Savings Plan (the Plan)  provides  only general  information.  Participants
     should refer to the plan  agreement for a more complete  description of the
     Plan's provisions.

     (A)  GENERAL

          The Plan is a participant-directed, contributory, defined contribution
          plan  subject to the  provisions  of the  Employee  Retirement  Income
          Security Act of 1974 (ERISA).

          During  1993,  the  MidSouth  Corporation  was acquired by Kansas City
          Southern Industries, Inc. and was merged into The Kansas City Southern
          Railway  Company (the  Company),  a wholly owned  subsidiary of Kansas
          City Southern  Industries,  Inc., on January 1, 1994. Effective May 2,
          2002, Kansas City Southern Industries, Inc. changed its name to Kansas
          City Southern.

          On January 1, 2001, the SouthRail  Corporation  Union Savings Plan was
          merged into the Plan.

     (B)  ELIGIBILITY

          The Plan covers all full-time employees of the Company who are members
          of one of the following  collective  bargaining  units with the former
          MidSouth  Rail  Corporation:   Brotherhood  of  Locomotive  Engineers,
          Brotherhood of  Maintenance  of Way Employees,  Brotherhood of Railway
          Carmen,  Brotherhood of Railroad Signalmen,  International Association
          of Machinists  and Aerospace  Workers,  International  Brotherhood  of
          Electrical Workers, Transportation Communications International Union,
          or United  Transportation Union. Plan entry dates are the first day of
          each quarter.

          A  participant  that  ends his or her  membership  in any of the above
          collective  bargaining  units is no longer eligible to receive Company
          contributions.  However,  such  participant  will  continue to receive
          credit for vesting  under the  provisions of the Plan and continues to
          share fully in trust fund allocations,  as set forth in the Plan. Upon
          rejoining  any  of  the  above  collective   bargaining   units,  such
          participant is then immediately  eligible to participate in all future
          Company contributions, as set forth in the Plan.

          Participants in the former  SouthRail  Corporation  Union Savings Plan
          and the  participants  in the MidSouth  Rail Union  401(k)  Retirement
          Savings Plan and Trust  Agreement who were employees of the Company on
          January 1, 2001, continue to be participants in the Plan.

     (C)  CONTRIBUTIONS

          Participants  may  contribute  a  portion  of  their  annual  eligible
          compensation,  as  defined  in the Plan,  not to exceed an  individual
          annual maximum  contribution  of $12,000 in 2003. The Company  matches
          100% of the first $200 of participant  salary  deferral  contributions
          and  50%  of  the  second   $600  of   participant   salary   deferral
          contributions,  with a maximum annual Company matching contribution of
          $500 per participant.

     (D)  PARTICIPANT ACCOUNTS

          Each   participant's   account  is  credited  with  the  participant's
          contribution,  the Company's matching contribution,  and an allocation
          of Plan earnings, net of investment expenses. Allocations are based on
          participant  earnings  or account  balances,  as set forth in the plan
          agreement.  The  benefit to which a  participant  is  entitled is that
          which can be provided from the participant's account.

     (E)  VESTING

          Participants   are   immediately   vested  in  their  salary  deferral
          contributions plus actual earnings thereon.

          Company contributions vest according to the following schedule:

                          Years of                     Percent
                          service
                  --------------------------------   -----------

                  Less than 1                              %
                                                        --
                  1                                      20
                  2                                      40
                  3                                      60
                  4                                      80
                  5 or more                             100

     (F)  INVESTMENT OPTIONS

          Upon   enrollment  in  the  Plan,  a  participant   may  direct  their
          contributions  and  Company  matching  contributions  into  any of the
          various funds offered by the Plan.

          Effective July 1, 2002, the Plan added Kansas City Southern (NYSE:KCS)
          common stock as an investment option.

          Participants  should  refer  to  the  respective  prospectuses  for  a
          description of the investment objective of each fund.

     (G)  BENEFITS

          Distributions  generally  will  be made in the  event  of  retirement,
          death, disability,  resignation,  or dismissal. A participant's normal
          retirement age is 65. The Plan also provides for  distribution  at age
          59 1/2.

          Distributions  after  termination  of  employment  will  be  made in a
          lump-sum  payment.  Balances  not  exceeding  $5,000  will be paid out
          within  one  calendar  year of  termination  of  employment.  Balances
          exceeding  $5,000 will be paid upon the  distribution  date elected by
          the participant, but no later than April 1 following the calendar year
          in which the participant attains the age of 70 1/2.

     (H)  PLAN TERMINATION

          Although it has  expressed  no intention to do so, the Company has the
          right to terminate the Plan at any time,  subject to the provisions of
          ERISA.  Upon termination of the Plan, the  participants  shall receive
          amounts equal to their respective account balances.

     (I)  PLAN EXPENSES

          Investment  expenses  are paid by the Plan as long as Plan  assets are
          sufficient to provide for such expenses.  Administrative  expenses are
          principally paid by the Company.

(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     (A)  BASIS OF PRESENTATION

          The Plan's financial  statements are presented on the accrual basis of
          accounting  and  present the net assets  available  for  benefits  and
          changes in those net  assets.  Benefit  payments to  participants  are
          recorded when paid.

     (B)  INVESTMENTS

          The fair value of marketable  securities is based upon quotations from
          national  securities  exchanges;  where marketable  securities are not
          listed on an exchange,  quotations are obtained from brokerage  firms.
          Securities  transactions are accounted for on the trade date (the date
          the order to buy or sell is executed).

          The assets held in the common  collective  trust (Invesco Stable Value
          Fund) are valued at contract value,  which approximates fair value, as
          determined by AMVESCAP National Trust Company.

     (C)  FORFEITURES

          Nonvested  amounts  forfeited by employees  are allocated to the other
          participants  as a  part  of and in the  same  manner  as the  Company
          contribution  for  the  Plan  year in  which  the  forfeiture  occurs.
          Allocated  forfeitures  were $190 and $5,463 for the Plan years  ended
          December 31, 2003 and 2002, respectively.

     (D)  USE OF ESTIMATES

          The preparation of financial  statements in conformity with accounting
          principles generally accepted in the United States of America requires
          management to make estimates and assumptions  that affect the reported
          amounts of assets,  liabilities,  and changes in net assets  available
          for benefits. Actual results could differ from those estimates.



(3)  INVESTMENTS

     Investments,  which exceeded 5% of the net assets available for benefits at
     December 31, 2003 and 2002, were as follows:

                                                       2003            2002
                                                   ------------    ------------
     Invesco Stable Value                          $ 1,034,694       1,046,912
     Franklin Balance Sheet Investment A               184,332         132,750
     PIMCO Renaissance                                 204,707         114,339
     PIMCO Total Return Administrative Shares          351,186         321,001
     Other                                             939,021         618,723
                                                   ------------    ------------
          Total Investments                        $ 2,713,940       2,233,725
                                                   ============    ============

     During 2003 and 2002, the Plan's investments (including gains and losses on
     investments  bought and sold, as well as held during the year)  appreciated
     (depreciated)  in  value  by  $320,409  and  ($216,986),  respectively,  as
     follows:

                                                       2003            2002

                                                   ------------    ------------
                                                   $   320,409        (216,986)
                                                   ============    ============

(4)  PLAN AMENDMENT

     Effective  April 1,  2002,  the Plan was  amended  and  restated  and a new
     trustee,   administrator   and  custodian  of  the  Plan  were   appointed.
     Accordingly,  the Plan was renamed  MidSouth  Rail Union 401(k)  Retirement
     Savings Plan. Plan assets  transferred to the new trustee were  transferred
     into funds  comparable  to those  offered by the  previous  custodian or as
     determined  by  a  formal  request  by  each  participant.  The  conversion
     initiated a "black out" period  beginning  March 15,  2002,  and  continued
     through  April 22, 2002.  During this period,  funds could not be withdrawn
     from the Plan and  investment  elections  could  not be  changed  until the
     trustee had time to accurately complete the conversion. During this period,
     employee contributions  continued to be made through payroll deductions and
     the contributions were deposited.

(5)  PORTFOLIO RISK

     The Plan provides for investments in various  securities  that, in general,
     are exposed to various risks,  such as interest rate,  credit,  and overall
     market  volatility  risks. Due to the level of risk associated with certain
     investment securities, it is reasonably possible that changes in the values
     of investment  securities will occur in the near term and that such changes
     could materially affect the amounts reported in the statement of net assets
     available for benefits.


(6)  INCOME TAX STATUS

     The Plan has  received a favorable  determination  letter from the Internal
     Revenue Service, dated March 7, 2003, indicating that it is qualified under
     Section  401(a) of the Internal  Revenue Code and,  therefore,  the related
     trust is exempt from tax under Section 501(a) of the Internal Revenue Code.
     The determination  letter is applicable for the amendments executed through
     April 1, 2002.

     The Company is not aware of any activity or transaction  that may adversely
     affect the qualified status of the Plan.
