Exhibit 99.1

                         PRO FORMA FINANCIAL INFORMATION


In  April  2003,  KCS  completed  the sale of  400,000  shares  of its  Series C
Preferred  Stock,  resulting in net proceeds of  approximately  $193.0  million.
Annual preferred stock dividends related to these shares are approximately  $8.5
million,  which will be reflected as a reduction of net earnings in  determining
earnings  available  to common  stockholders  and  earnings per share in periods
following the sale of the Series C Preferred Stock. Additionally,  to the extent
that the assumed  conversion  of these shares into  13,389,121  shares of common
stock would have a dilutive  impact on earnings  per share,  such shares will be
included in the computation of diluted earnings per share in future periods.

In April 2003,  KCS and Grupo TMM announced a series of  transactions  that were
approved by both  respective  boards of  directors,  that would,  following  KCS
shareholder  approval and satisfaction of other conditions,  place KCSR, Tex-Mex
and TFM under the common  control of a single  transportation  holding  company,
NAFTA Rail.  Grupo TFM holds an 80% interest in TFM, which holds a 100% interest
in Mexrail. Mexrail wholly-owns Tex-Mex.

Under the terms of the agreement,  Multimodal,  a subsidiary of Grupo TMM, would
receive 18  million  shares of NAFTA Rail  representing  approximately  22% (20%
voting,  2% subject to voting  restrictions) of NAFTA Rail  outstanding  shares,
$200 million in cash and a potential  incentive  payment of between $100 million
and $180 million based upon the resolution of certain future contingencies.  See
Note 17 of the Notes to Pro Forma Condensed  Consolidated  Financial  Statements
for further information.

On August 23, 2003,  Grupo TMM sent a notice to KCS  claiming to  terminate  the
Acquisition  Agreement  because  Grupo TMM  shareholders  failed to approve  the
Acquisition Agreement.  Accordingly,  while KCS intends to pursue all reasonable
legal means available to it in enforcing the Acquisition Agreement, no assurance
can be given  that KCS will be able to  consummate  the  Acquisition.  See "Risk
Factors--KCS  Risk  Factors--Risks  Related to Our Business--We may be unable to
complete the Acquisition."

Notwithstanding this uncertainty, the following pro forma condensed consolidated
financial  statements are presented to illustrate the impact of the  Acquisition
on KCS's historical  financial  statements and reflect the effect of the various
transactions  necessary to consummate the agreements as if the  transaction  had
occurred  on January 1, 2003 and January 1, 2004 for income  statement  purposes
for the year ended  December 31, 2003 and the three months ended March 31, 2004,
respectively,  and  as of  March  31,  2004  for  balance  sheet  purposes.  The
historical  financial  statements of Grupo TFM are prepared under the principles
of  International   Financial   Reporting   Standards  ("IFRS")  and  include  a
reconciliation between U.S. Generally Accepted Accounting Principles ("US GAAP")
and IFRS. The Grupo TFM historical  financial  information included in these pro
forma  financial  statements  is  reflected  under  US  GAAP  and  therefore  no
reconciliation of financial information between US GAAP and IFRS is required for
these purposes.




The  following  summarizes  selected  pro  forma  financial  information  of KCS
assuming the transaction  acquiring a controlling interest in Grupo TFM had been
completed as of March 31, 2004.

                              KANSAS CITY SOUTHERN
         NOTES TO PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: REMOVAL OF THE EQUITY INVESTMENT IN GRUPO TFM & MEXRAIL

Pursuant to the  Acquisition  Agreement,  Kansas City Southern (the "Company" or
"KCS") would acquire a controlling interest in Grupo Transportacion  Ferroviaria
Mexicana,  S.A. de C.V.  ("Grupo TFM"),  resulting in the full  consolidation of
Grupo TFM's balance sheet into NAFTA Rail,  successor to KCS.  Accordingly,  the
equity  investment  as of March 31, 2004  reflected on the  Company's  condensed
consolidated balance sheet would be eliminated. KCS and Grupo TMM are in dispute
over Grupo TMM's attempt to terminate  the  agreement  entered into on April 20,
2003 by KCS and Grupo  TMM and  other  parties  under  which  KCS would  acquire
control of TFM.


On May 9, 2003,  the  Company  closed on its 51%  investment  in  Mexrail,  Inc.
("Mexrail")  for a total of $32.7  million.  The Mexrail shares were placed in a
voting trust while  awaiting the  approval of the Surface  Transportation  Board
("STB"). On August 29, 2003, KCS received a demand by TFM to repurchase from KCS
shares of Mexrail sold to KCS in May 2003. On September 23, 2003, the STB issued
a  decision  finding  no need to  rule  on the  transfer  back to TFM of the 51%
interest in Mexrail that KCS acquired on May 9, 2003. On September 30, 2003, TFM
repurchased  the Mexrail  shares from KCS at the price KCS paid TFM in May 2003.
Accordingly,  Grupo TFM continues to consolidate the balance sheet and operating
results of Mexrail.

NOTE 2: CREATION OF IDENTIFIABLE INTANGIBLE ASSETS

Additional  identifiable  intangibles  or goodwill may result from the Grupo TFM
acquisition.  The current  value of the  consideration  to obtain a  controlling
interest  in Grupo TFM  exceeds the  current  book value of the  underlying  net
assets by  approximately  $7.0  million,  which is  reflected  on the  condensed
consolidated  pro forma balance sheet as an addition to concession  assets.  The
Company has not completed a fair value appraisal or any associated allocation of
excess  purchase price to the fair value of tangible  assets as of this date. At
the time those  processes are  completed,  the  allocation of the purchase price
could change and may include certain  identifiable  intangibles  assets, such as
customer  contracts,  customer  relationships  or similar items. For purposes of
these pro forma financial statements,  the Company has assumed the difference in
value will be assigned to concession assets.

NOTE 3: RECOGNITION OF THE DEFERRED GAIN ON THE SALE OF MEXRAIL

On April 1, 2002,  the Company sold its 49% interest in Mexrail to TFM for $31.4
million  resulting in a pre-tax gain of $4.4 million,  which was reported in the
Company's Consolidated Statement of Income for the year ended December 31, 2002.
In addition,  the transaction resulted in the recognition of a deferred gain, of
which $6.1  million  remained  unamortized  as of March 31,  2004.  Assuming the
transaction   contemplated  had  occurred  on  March  31,  2004,  the  remaining
unamortized gain on the April 2002 Mexrail  transaction would be eliminated from
the Company's long-term  liabilities and reflected with an offsetting adjustment
to concession assets as part of the transaction. Also see Note 2.




NOTE 4: TRANSACTION FINANCING

As described above, part of the transaction  consideration includes a payment of
$200  million.  This  payment may be made by the  Company,  at its option,  in a
combination  of  additional  common  stock  issuance to Grupo TMM and cash.  For
purposes of these pro forma financial  statements,  the Company has assumed that
the entire  payment of $200 million will be made in cash with a  combination  of
the  net  proceeds  of the  sale  of  4.25%  Redeemable  Cumulative  Convertible
Perpetual  Preferred  Stock,   Series  C  ("Convertible   Preferred  Stock")  of
approximately $193.0 million, completed in April 2003, with the remainder funded
from proceeds from borrowings under the Company's credit facility. The pro forma
financial  statements presented herein reflect the effect of these transactions.
Also see Note 7.

The Convertible  Preferred Stock is redeemable at the option of a holder only in
the event of a  "fundamental  change",  which is defined as "any  transaction or
event  (whether  by means  of an  exchange  offer,  liquidation,  tender  offer,
consolidation,  merger,  combination,   reclassification,   recapitalization  or
otherwise) in connection  with which all or  substantially  all of the Company's
Common stock is  exchanged  for,  converted  into,  acquired for or  constitutes
solely the right to receive  common stock that is not listed on a United  States
national  securities  exchange or approved for quotation on the Nasdaq  National
Market or similar system. The practical effect of this provision is to limit the
Company's  ability to  eliminate a holder's  ability to convert the  Convertible
Preferred  Stock into  common  shares of a publicly  traded  security  through a
merger or consolidation  transaction.  In no other  circumstances is the Company
potentially  obligated  to  redeem  the  Convertible  Preferred  Stock for cash.
Accordingly,  since the  Company  is in a  position  to  control a  "fundamental
change" the  Convertible  Preferred  Stock is  classified  as  permanent  equity
capital.

NOTE 5:  ADJUSTMENTS TO INTEREST INCOME AND INTEREST EXPENSE

The proforma condensed consolidated income statement for the year ended December
31, 2003 and the three  months  ended March 31, 2004  reflect a $1.2 million and
$0.3  million  reduction to interest  income,  respectively.  These  adjustments
reflect the fact that,  assuming the Acquisition had been  consummated as of the
beginning of each  proforma  income  statement  presented,  the  Company's  cash
balance that had arisen from the  issuance of the  Convertible  Preferred  Stock
would have been used to fund the $200 million payment described above, and thus,
interest  income  relating to that cash  balance  would not have been  realized.
Similarly,  had the  Acquisition  been  consummated  as of the beginning of each
proforma income statement period  presented,  cash would not have been available
to pay down $49.3 million of debt during  December 2003 and $38.5 million during
March 2004.  Therefore,  an adjustment has been made to the pro forma  condensed
consolidated  income statements to increase interest expense by $0.1 million for
the year ended  December  31, 2003 and $0.6  million for the three  months ended
March 31, 2004.

NOTE 6: ELIMINATION OF GRUPO TFM STOCKHOLDERS' EQUITY

As a result of NAFTA Rail  obtaining a  controlling  interest in Grupo TFM,  its
assets and liabilities would be consolidated with NAFTA Rail. Accordingly, Grupo
TFM's  stockholders'  equity  amounts would be  eliminated in the  consolidation
process.

NOTE 7: ISSUANCE OF NEW SECURITIES

As noted above,  Grupo TMM will receive as consideration  for the transaction 18
million shares of NAFTA Rail. This pro forma adjustment reflects the addition to
stockholders'  equity  of a total of $202.7  million  of  equity  based  upon 18
million  common  shares as part of the initial  agreement  and  assuming a stock
price of $11.26 per share.  The assumed stock price was derived by averaging the
closing price of the Company's common stock five days before and five days after
the  announcement of the transaction on April 21, 2003. The total  allocation of
the new capital is $0.2 million,  which is comprised of 18 million shares of new
non-voting  common stock with a par value of $.01 per share and $202.5  million,
which is reflected as capital surplus representing the value of the stock issued
in  excess  of par.  Note the  cost of the  purchase  would  have  increased  by
approximately $56 million if a current stock price of $13.97 per share was used.
This stock price of $13.97 was  determined by averaging the closing price of the
Company's  common stock five days before and five days  subsequent  to March 31,
2004.  In the event the terms of the  Acquisition  Agreement  are  substantially
modified,  the actual purchase price and resulting purchase  accounting would be
adjusted to reflect current prices.

In April  2003,  the  Company  issued  400,000  shares of $1.00 par value  4.25%
Convertible  Preferred Stock resulting in net proceeds of  approximately  $193.0
million  (net  of fees of  approximately  $7.0  million).  This  transaction  is
reflected in the  accompanying KCS historical  consolidated  balance sheet as of
March 31, 2004 as new capital of $0.4 million, capital surplus of $110.9 million
and retained earnings of $81.7 million.

Holders of the Convertible Preferred Stock are entitled to receive any dividends
declared by the  Company's



board of directors at the rate of 4.25% per annum,  payable quarterly in arrears
on  February  15, May 15,  August 15 and  November  15 of each year,  commencing
August 15, 2003. The dividends are cumulative from the date of initial  issuance
and accumulated but unpaid  dividends  cumulate  dividends at the annual rate of
4.25%. In addition, the Company will also pay "special dividends" if it fails to
comply with certain obligations under a registration rights agreement.  A holder
may convert its Convertible  Preferred Stock into shares of the Company's Common
Stock only under  certain  circumstances,  relating to: (i) the trading price of
the Company's Common Stock;  (ii) a credit rating  downgrade;  (iii) the trading
price per share of the  Convertible  Preferred  Stock;  (iv)  redemption  of the
Convertible  Preferred  Stock;  and  (v) the  occurrence  of  certain  corporate
transactions.

The  conversion  rate may be adjusted  upon the  occurrence  of certain  events.
Subject to certain  conditions,  on or after May 20, 2008, the Company will have
the option to redeem some or all of the shares of Convertible Preferred Stock at
a redemption price of 100% of the liquidation  preference,  plus accumulated and
unpaid dividends, if any, to the redemption date. In the event of a "fundamental
change,"  the Company may be  required  to  purchase  shares of the  Convertible
Preferred  Stock at the  option of the  holder  at a price  equal to 100% of the
liquidation  preference  plus any accumulated  and unpaid  dividends,  including
special dividends, if any, to, but excluding, the purchase date.

The Company may elect to pay the  purchase  price in cash,  Common  Stock,  or a
combination  of cash and Common  Stock.  If the  Company  elects to pay all or a
portion of the purchase  price in shares of Common Stock,  the Common Stock will
be  valued  at a  specified  discount.  The  Company  agreed  to file  with  the
Securities and Exchange  Commission a shelf registration  statement with respect
to the resale of the  Convertible  Preferred Stock and the Common Stock issuable
upon  conversion  of the  Convertible  Preferred  Stock  and to keep  the  shelf
registration  statement  effective for a specified  period of time. In addition,
the  Company  will be required  to pay to holders of the  Convertible  Preferred
Stock liquidated  damages in the form of special dividends or liquidated damages
payments,  as  applicable,  if the  Company  fails to register  the  Convertible
Preferred Stock and the Common Stock issuable upon conversion of the Convertible
Preferred  Stock  within,  and to keep  such  registration  statement  effective
during, the specified time periods.

NOTE 8: ELIMINATION OF EQUITY BASIS DIFFERENCE IN GRUPO TFM

The calculation of the Company's net equity in Grupo TFM's underlying net assets
utilizing the Company's current ownership  percentage of approximately  46.6% as
compared  to the  amount  recorded  as an  investment  as of March  31,  2004 of
approximately  $393.4  million  results in a basis  difference of  approximately
$13.4 million.  This  difference in basis results from a number of factors,  the
most significant of which is the changing ownership interest in Grupo TFM, which
produced a difference  in  investment  basis that occurred when TFM acquired the
Mexican  Government's  24.6%  interest  in Grupo TFM  during  2002.  This  basis
difference would have been amortized over time; however, due to the contemplated
transaction wherein the Company will obtain a controlling interest in Grupo TFM,
the  remaining  basis   difference  will  be  recognized  at  the  date  of  the
transaction.  The pro forma financial  statements as stated herein recognize the
elimination of this basis difference as an addition to concession  assets on the
condensed consolidated balance sheet. See Note 2.

NOTE 9: ELIMINATION OF EQUITY EARNINGS FROM GRUPO TFM

Assuming the contemplated  transaction would have been consummated on January 1,
2003 or January 1, 2004,  as  applicalbe,  the Company  would have  consolidated
earnings of Grupo TFM and accordingly, the equity in earnings of Grupo TFM would
be eliminated.



NOTE 10: PROVISION FOR INCOME TAXES / DEFERRED INCOME TAXES

The pro forma condensed  consolidated  income statement  reflects the income tax
impacts of the pro forma adjustments utilizing an income tax rate of 38.25%, but
excluding  any  consideration  of the equity  earnings  of Grupo TFM,  since the
Company has not previously provided a tax provision on these amounts.

In addition, the recognition of additional identifiable intangible assets in the
form  of  concession  assets  creates  an  additional   deferred  tax  liability
associated with those assets. The pro forma condensed consolidated balance sheet
as of March 31, 2004 recognizes the deferred tax liability of approximately $8.8
million using the tax rate noted above.

NOTE 11: CONSOLIDATION ELIMINATIONS

These pro forma  adjustments  reflect the  elimination of  intercompany  amounts
between the Company,  Grupo TFM and Mexrail,  assuming the three  entities  were
consolidated for financial reporting purposes.

NOTE 12: COMPUTATION OF EARNINGS PER SHARE

Basic earnings per share for the purposes of the pro forma  consolidated  income
statement  reflect pro forma  consolidated  net income,  less  dividends  on the
Company's $25 par  preferred  stock of  approximately  $242,000  annually,  less
dividends on the Company's $.01 par Convertible Preferred Stock of approximately
$8.5 million  annually,  divided by the weighted average  outstanding  shares as
described in Note 13 below.  Note the  proforma  adjustment  includes  only $2.8
million for preferred  dividends as the historical  financial  statements of the
Company reflect $5.7 million of dividends  related to the Convertible  Preferred
Stock for the year ended  December 31, 2003 and $0.2 million  related to the $25
par preferred stock.

Diluted  earnings  per share  for the  purposes  of the pro  forma  consolidated
condensed income  statements  reflect pro forma  consolidated  net income,  less
dividends on the  Company's $25 par preferred  stock of  approximately  $242,000
annually,  divided  by  the  weighted  average  diluted  outstanding  shares  as
described in Note 13 below.

The assumed  conversion of the Company's $1.00 par  Convertible  Preferred Stock
(convertible into 13,389,121 common shares) would have been anti-dilutive to the
pro  forma  diluted  earnings  per  share  computations  in each of the  periods
presented.  Accordingly,  conversion of preferred  shares into common shares was
not assumed and these shares were not included in the pro forma diluted earnings
per share computations. Total preferred dividends, however, were subtracted from
net income in the computation of the pro forma diluted earnings per share.

NOTE 13: WEIGHTED AVERAGE SHARES OUTSTANDING

The weighted  average basic shares  outstanding  are  calculated  beginning with
Company  historical average basic shares (61,725,000 for the year ended December
31,  2003 and  62,504,000  for the  three  months  ended  March 31,  2004)  plus
18,000,000 assumed shares to be issued as described in Note 7 above.

For the three months ended March 31, 2004, the weighted  average  diluted shares
outstanding  are calculated  beginning with Company  historial  average  diluted
shares of 63,811,000 plus 18,000,000 assumed shares to be issued as described in
the Note 7 above,  but excluding the 13,389,121  shares assuming full conversion
of the Convertible  Preferred  Stock into common  utilizing a conversion rate of
33.4728 for each share of preferred to common.  As stated in Note 12 above,  the
inclusion of the 13,389,121 shares would have had an anti-dilutive effect on the
computations of pro forma dilutive earnings per share.

For the year ended  December  31,  2003,  the weighted  average  diluted  shares
outstanding  are calculated  beginning with Company  historical  average diluted
shares of 61,725,000  plus 1,375,000  shares assumed for the conversion of stock
options that were treated as anti-dilutive for the calculation of the historical
diluted earnings per share computation but would be dilutive under the pro forma
dilutive  earnings per share  computation  plus 18,000,000  assumed shares to be
issued as described in Note 7 above, but excluding the



13,389,121  shares assuming full  conversion of the Convertible  Preferred Stock
into common  utilizing a conversion  rate of 33.4728 for each share of preferred
to common.

NOTE 14: CONSULTING AGREEMENT

In  connection  with the  transaction,  the  Company  intends  to  enter  into a
consulting  agreement with a consulting firm  ("Consultant")  controlled by Jose
Serrano  Segovia  with an  initial  term of three  years.  In  consideration  of
services  provided,  Consultant  will  receive an annual fee of $0.6  million in
cash,  plus up to 2.1 million shares of restricted  common stock of the Company.
The  restricted  stock vests  based upon the  achievement  of certain  events as
defined  in the  consulting  agreement  and/or  ratably  over  the  term  of the
agreement  in  certain  circumstances.  The  pro  forma  condensed  consolidated
financial statements herein reflect the effect of these transactions as follows.
The restricted  stock will be accounted for as  compensation  expense based upon
the assumed  fair market value at date of vesting and expensed in the period the
stock vests.

The annual fee is reflected as additional  operating  costs and expenses of $0.6
million  for the year ended  December  31,  2003 and $0.1  million for the three
months ended March 31, 2004. An initial 750,000 shares of restricted  stock vest
ratably over the term of the agreement. For purposes of the pro forma statements
of income,  the Company has assumed a  calculated  value of stock based upon the
stock  price of $14.49 for the year ended  December  31, 2003 and $13.97 for the
three  months  ended  March 31,  2004,  which are the stock  prices  derived  by
averaging of the closing  price of the  Company's  common stock five days before
and five days after  December  31, 2003 and March 31,  2004,  respectively.  The
resulting  amounts are  reflected  as  compensation  expense and  amortized on a
straight line basis over three years.  The  additional  compensation  expense is
approximately $3.6 million for the year ended December 31, 2003 and $0.9 million
for the three  months  ended March 31,  2004.  The Company  recognizes  that the
prospective  accounting  for these  shares will  result in  variable  accounting
treatment and the resulting  expense will be dependent upon the Company's  stock
price at the actual time the stock vests.  Since the Company  cannot predict the
future price of the Company's stock, the pro forma adjustments  assume the stock
prices as noted above.

The consulting  agreement  provides for additional  vesting of restricted  stock
totaling 1,350,000 shares, in increments of 525,000,  125,000 and 700,000 shares
depending on the  achievement of certain  events  ("contingent  shares").  These
events  include the  completion of an agreement with TFM labor unions and events
related to the VAT tax issue.  While the Company  cannot  predict  the  ultimate
timing of  achievement  of these  events and thus their pro forma  effect on the
adjusted financial  statements,  the Company would intend to record compensation
expense at the time and in the quarter or annual  period in which  these  shares
vest,  at then  fair  value as  determined  by the  Company's  stock  price.  No
adjustments for these contingent shares have been made in the attached pro forma
financial statements due to the uncertainty of their realization and vesting.

The calculated value of these contingent  shares is approximately  $18.9 million
based upon the stock price of $13.97 as noted  above.  The actual  impact to the
Company's financial statements related to the restricted stock is dependent upon
the price of the  Company's  stock at the time the  restricted  stock  vests and
which the Company  cannot  predict.  A $1.00 per share change,  either higher or
lower, in the Company's stock price at the time the restricted stock vests could
result in higher or lower  compensation  expense of approximately  $1.4 million,
assuming all 1.35 million contingent shares vested at the same time.



NOTE 15: AMORTIZATION OF IDENTIFIABLE INTANGIBLES - CONCESSION ASSETS

The  transactions  as described  above  result in a net  addition to  concession
assets of approximately $23.0 million, including $8.8 million of deferred income
tax impact  described  in Note 10 above.  For  purposes of the pro forma  income
statements  presented  herein,  this  balance is  amortized  over the  remaining
amortizable  life  of  the  concession  assets  of 33  years.  This  results  in
additional amortization expense of approximately $0.8 million for the year ended
December 31, 2003 and $0.2 million for the three months ended March 31, 2004.

NOTE 16: MINORITY INTEREST

As previously reported,  TFM repurchased the Mexican Government's 24.6% interest
in Grupo TFM in June 2002.  Since the purchase of the Mexican  Government  24.6%
interest  was  completed by Grupo TFM's  subsidiary,  TFM, and the fact that the
Mexican  Government  also continues to maintain a 20% minority  interest in TFM,
the Mexican  Government  retained an indirect 4.9448% minority interest in Grupo
TFM through its  ownership of TFM. The pro forma  adjusting  entries to minority
interest reflect the continuing  indirect minority ownership in Grupo TFM by the
Mexican  Government  for the  periods  indicated.  For the pro  forma  condensed
consolidated  balance sheet as of March 31, 2004, an additional $40.3 million of
minority  interest was added to the pro forma balances  representing  4.9448% of
Grupo  TFM's  net  assets.  For  the pro  forma  condensed  consolidated  income
statements,  the amount of  minority  interest in Grupo TFM's US GAAP net income
was computed for the periods presented  resulting in approximately  $1.4 million
for the year ended December 31, 2003 and $0.1 million for the three months ended
March 31, 2004.

NOTE 17: VAT RELATED MATTERS

The impact of any  settlement  of the VAT  dispute  between  TFM and the Mexican
Government on the Company's  consolidated financial statements will be dependent
upon the timing and amount of any such settlement.

It is expected  that the value of any  consideration  received  from the Mexican
Government  from the settlement of the VAT dispute will be recorded as income by
TFM and Grupo TFM,  net of  related  income  taxes.  If a binding  agreement  is
reached before the consummation of the Acquisition, the Company would record its
proportionate  share of any such gain  through  its equity in  earnings of Grupo
TFM,  based  upon  its  existing  ownership  of  46.6%.  If the  Acquisition  is
subsequently consummated, the proceeds from any settlement received and retained
by TFM,  including  the impacts of any  additional  consideration  as may become
payable as  discussed  below,  would  impact  the  Company's  allocation  of the
purchase price to assets  acquired and  liabilities  assumed,  likely  impacting
amounts otherwise  allocable to long-lived  assets,  including  intangibles,  as
presented herein.

If the VAT dispute were settled  following the  consummation of the Acquisition,
the  Company  would  record in income its  proportionate  share of any such gain
through its  consolidation of the operating results of Grupo TFM, based upon its
pre-acquisition   ownership   interest  of  46.6%.   The  portion  of  any  gain
attributable  to  the



acquired  interest  of Grupo  TMM  would  likely  constitute  a  pre-acquisition
contingency and not impact the Company's operating results,  but rather would be
considered  in the  allocation  of the  purchase  price to assets  acquired  and
liabilities  assumed,  likely reducing amounts otherwise allocable to long-lived
assets, including intangibles, as presented herein.

Pursuant  to the terms of the  Acquisition,  if the  value of the  consideration
received by TFM in connection with the settlement of the VAT dispute exceeds the
amount  payable  pursuant  to the Put  Agreement  in place  between  the Mexican
Government, Grupo TFM, Grupo TMM and the Company, whereby the Mexican Government
may put its ownership in TFM to the other  parties,  additional  amounts will be
payable  by the  Company or TFM to Grupo  TMM,  depending  on the amount of such
excess.  Such payment  would range from $100 million to $180  million.  Any such
payment  would  constitute  additional  consideration  for the purchase of Grupo
TMM's interest in Grupo TFM and as such would likely increase amounts  allocable
to long-lived assets, including intangibles, as presented herein.

NOTE 18:  CONSIDERATION OF THE MEXICAN GOVERNMENT'S PUT RIGHTS REGARDING ITS 20%
MINORITY INTEREST IN TFM

The provisions of the "Put Agreement"  obligate Grupo TFM or KCS to purchase the
Mexican  Government's 20% minority interest in TFM under certain conditions.  As
disclosed in the Company's  Form 10-Q for the three months ended March 31, 2004,
the total estimated purchase price of the Mexican Government's minority interest
was  approximately  $478  million.  The  calculation  of the  purchase  price is
dependent upon inflationary  factors of the Mexican economy and foreign exchange
rate  factors,  which the Company can not predict.  While the Company along with
Grupo TFM are currently  exploring financing  alternatives,  the source and cost
any such financing for this  obligation is not reasonably  determinable  at this
time . In addition,  the  acquisition of the Mexican  Government's  interest and
funding of this  obligation  could be affected by the outcome and  settlement of
TFM's VAT dispute with the Mexican Government.

Due to the  uncertainties  noted above,  the  accompanying  pro forma  financial
statements do not reflect the impact of the acquisition of additional  shares of
TFM which could arise under the Put Agreement. If, following the consummation of
the  acquisition  of Grupo TFM shares from Grupo TMM,  the Company  acquires the
remaining  shares  of TFM held by the  Mexican  Government  pursuant  to the Put
Agreement,  the accompanying  pro forma financial  statements would be generally
impacted as follows. The excess of the purchase price over the carrying value of
minority interest would be allocated to the assets and liabilities of Grupo TFM,
based upon their  fair  values,  with the likely  impact  being an  increase  to
recorded  amounts for long-lived  assets,  including  intangibles,  as presented
herein.  Additionally,  the minority  interest in earnings of Grupo TFM would be
eliminated from the pro forma income statement,  offset by the costs of any debt
financing  incurred to finance the purchase and any increases in depreciation or
amortization expense relating to the application of purchase accounting.
