             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



The Participants and Plan Sponsor
Gateway Western Railway Union 401(k) Plan:


We have audited the accompanying statements of net assets available for benefits
of the Gateway  Western  Railway Union 401(k) 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.

                           December 31, 2003 and 2002



(1)  DESCRIPTION OF THE PLAN

     (A)  GENERAL

          The Gateway  Western Railway 401(k) Plan (the Plan) is a contributory,
          defined contribution plan adopted on July 1, 1997. The Plan is subject
          to the provisions of the Employee  Retirement  Income  Security Act of
          1974 (ERISA).

          The following  brief  description  of the Plan is provided for general
          information  purposes  only.  Participants  should  refer  to the plan
          agreement for a more complete description of the Plan.

     (B)  ELIGIBILITY

          The Plan  covers  union  employees  of Kansas  City  Southern  Railway
          Company, located from Kansas City to East St. Louis (the Company), who
          are  members  in  a  craft   represented   by  one  of  the  following
          organizations:   Transportation  Communications  International  Union,
          Brotherhood of Locomotive Engineers, Brotherhood of Maintenance of Way
          Employees, Brotherhood of Railway Signalmen, International Brotherhood
          of Electrical  Workers,  International  Association  of Machinists and
          Aerospace  Workers,  or Brotherhood of Railway  Carmen.  Employees are
          eligible to participate in the Plan on the January 1, April 1, July 1,
          or October 1 coincident with or immediately following his or her first
          day of employment.

     (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
          50%  of  participant  contributions,  up  to  6%  of  annual  eligible
          compensation.

     (D)  PARTICIPANT ACCOUNTS

          Each   participant's   account  is  credited  with  the  participant's
          contribution, Company 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  contributions,  Company
          matching contributions, plus actual plan earnings thereon.

     (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  distributions 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

          All administrative expenses of the Plan are 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 a common  collective  trust  (Invesco  Stable Value
          Fund) are  valued at  contract  value as  determined  by the  AMVESCAP
          National Trust Company.

     (C)  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  plan
     benefits at December 31, 2003 and 2002, were as follows:

(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.  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 from 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  received  a  favorable  determination  letter  from the  Internal
     Revenue Service, dated July 15, 2003, indicating that it is qualified under
     Section 401(a) of the Internal Revenue Code (the Code) and, therefore,  the
     related  trust is exempt  from tax under  Section  501(a) of the Code.  The
     determination letter is applicable for amendments executed through June 30,
     2003.

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