Kansas City Southern Industries, Inc.

Kansas City, MO  64105

Dear Ladies and Gentlemen:

     We have acted as tax counsel to Kansas City  Southern  Industries,  Inc., a
Delaware  corporation  (the  "Company"),  in connection with the issuance of the
Company's   Mandatory   Convertible  Units  ("Convertible   Units"),   initially
consisting  of units  (referred  to as  "Corporate  Units")  comprised  of stock
purchase  contracts and senior notes due 2007 (the "Notes") issued by The Kansas
City  Southern  Railway  Company,  a  wholly-owned  subsidiary  of  the  Company
("KCSR"), and guaranteed by the Company and certain of its subsidiaries.

     In  formulating  our opinion,  we have reviewed such documents as we deemed
necessary or appropriate,  including (i) the Registration  Statement on Form S-3
filed with the U.S. Securities and Exchange Commission (the "Commission") on May
16, 2001, pursuant to the Securities Act of 1933, and declared effective June 5,
2001 (the "Registration Statement"); (ii) the Prospectus of the Company that was
included in the Registration Statement on Form S-3 (the "Prospectus"); (iii) the
form of  Indenture,  between the  Company  and The Bank of New York,  a New York
banking  corporation,  as  trustee  (the  "Trustee")  filed as an exhibit to the
Registration  Statement;  (iv) the form of Purchase Contract Agreement,  between
the Company and Bank of New York, filed as an exhibit to a document incorporated
by reference in the Prospectus which forms part of the  Registration  Statement,
(v) the form of Pledge  Agreement  between the Company,  Chase Manhattan Bank as
collateral agent, and The Bank of New York as Purchase Contract agent,  filed as
an exhibit to a document incorporated by reference in the Prospectus which forms
part of the  Registration  Statement,  (vi) the form of  Remarketing  Agreement,
between the Company and J.P. Morgan Securities Inc., as remarketing agent, filed
as an exhibit to a document  incorporated  by reference in the Prospectus  which
forms part of the Registration Statement.

     We have also  participated  in the  preparation  of the  Supplement  to the
Prospectus  for  the  Convertible  Units,  forming  a part  of the  Registration
Statement (the "Prospectus  Supplement").  In addition,  we have made such other
factual and legal inquiries as we have considered necessary or appropriate.

     Our opinion set forth below assumes (i) the initial and continuing accuracy
of the statements and facts  concerning the  Convertible  Units set forth in the
Registration Statement, the Prospectus and the Prospectus Supplement and certain
other documents;  (ii) the conformity of the Convertible  Units to the terms set
forth  in  the  Registration  Statement,   the  Prospectus  and  the  Prospectus
Supplement; (iii) the execution of the Indenture, Pledge Agreement,  Remarketing
Agreement  and  Purchase  Contract  in  substantially  the same form as filed as
exhibits  to the  Registration  Statement  as  set  forth  above  and  (iv)  the
genuineness  of all  signatures,  the legal  capacity  of natural  persons,  the
authenticity of all documents  submitted to us as originals,  and the conformity
to original documents of all documents  submitted to us as photocopies.  We also
have assumed that the  transactions  related to the issuance of the  Convertible
Units  will  be  consummated  in the  manner  contemplated  by the  Registration
Statement, the Prospectus and the Prospectus Supplement.

     Based  upon the  foregoing  and in  reliance  thereon,  and  subject to the
qualifications, exceptions, assumptions and limitations herein contained, we are
of the opinion that:

          (1) the  discussion  in the  Prospectus  Supplement  under the heading
     "Certain  Federal  Income Tax  Consequences"  constitutes,  in all material
     respects,  a fair and accurate  summary of the matters  addressed  therein,
     based on the assumptions stated or referred to therein; and

          (2) the  Notes  will be  treated  as  indebtedness  of KCSR  for U. S.
     federal income tax purposes.

     We express no opinion  concerning any tax consequences  associated with the
Convertible Units other than those specifically set forth herein.

     Our opinion is based on current  provisions of the Internal Revenue Code of
1986,  as  amended,  Treasury  Regulations  promulgated  thereunder,   published
pronouncements  of the Internal Revenue Service,  and case law, any of which may
be changed at any time with retroactive  effect. Any change in applicable law or
the facts and circumstances surrounding the Convertible Units, or any inaccuracy
in the statements,  facts, assumptions,  and representations on which we relied,
may affect the continuing validity of the opinion set forth herein. We assume no
responsibility to inform you of any such changes or inaccuracy that may occur or
come to our attention.

     This opinion is furnished to you solely for your benefit in connection with
the offering of the Convertible Units and is not to be used, circulated,  quoted
or  otherwise  referred  to for any other  purpose  or relied  upon by any other
person  without  our prior  written  consent.  We consent to the use of our name
under the heading  "Certain  Federal Income Tax  Consequences" in the Prospectus
Supplement.  We hereby consent to the filing of this opinion with the Commission
as Exhibit 8.1 to the Registration  Statement. In giving this consent, we do not
hereby  admit that we are  within  the  category  of  persons  whose  consent is
required under Section 7 of the Securities Act of 1933, as amended, or the rules
and regulations of the Commission promulgated thereunder.

                                                       Very truly yours,

                                              SONNENSCHEIN NATH & ROSENTHAL


                                            /s/  Sonnenschein Nath & Rosenthal
