         This Amendment No. 1 ("Amendment No. 1 to Schedule 13D") amends the
statement of beneficial ownership on Schedule 13D filed on December 21, 2000
(the "Schedule 13D") by and on behalf of Mortimer B. Fuller, III (the "Reporting
Person") with respect to the class A common stock, par value $.01 per share (the
"Class A Common Stock"), of Genesee & Wyoming Inc., a Delaware corporation (the
"Company"), beneficially owned by the Reporting Person. Capitalized terms used,
but not defined, herein have the meanings ascribed thereto in the Schedule 13D.

Item 1.  Security and Issuer

         No change.

Item 2.  Identity and Background

         No change.

Item 3.  Source and Amount of Funds or Other Consideration

         Pursuant to a Stock Purchase Agreement by and between the Company and
The 1818 Fund III, L.P., a Delaware Limited Partnership (the "Fund") dated
October 19, 2000 (the "Stock Purchase Agreement"), on December 12, 2000, the
Company issued, and the Fund acquired from the Company 20,000 shares of
Preferred Stock.

         The consideration paid by the Fund for the shares of Preferred Stock it
purchased under the Stock Purchase Agreement on December 12, 2000 was
$20,000,000 in cash, which was obtained by the Fund from capital contributions
made by its partners pursuant to pre-existing capital commitments.

         On December 11, 2001, in accordance with Section 2.1(b)(ii) of the
Stock Purchase Agreement, the Company issued, and the Fund acquired from the
Company an additional 5,000 shares of Preferred Stock.

         The consideration paid by the Fund for such shares of Preferred Stock
was $5,000,000 in cash, which, to the knowledge of the Reporting Person, was
obtained by the Fund from capital contributions made by its partners pursuant to
pre-existing capital commitments.

         As previously reported in the Reporting Person's Schedule 13D, as a
condition to the Fund acquiring the 20,000 shares of Preferred Stock on December
12, 2000, the Reporting Person, the Company and the Fund were required to enter
into the Letter Agreement. Pursuant to the Letter Agreement, the Reporting
Person has agreed, so long as the Fund continues to own at least 20% of the
shares of Class A Common Stock issued or issuable upon conversion of the
Preferred Stock, to vote all shares of the capital stock of the Company (whether
now or hereafter acquired) owned (whether jointly or severally) or, to the
extent permitted by law, controlled (including shares held by the Estate of
Frances A. Fuller until distributed in accordance with Section 2(f) of the
Letter Agreement, but excluding shares held by the Overlook Estate Foundation,
Inc. or the Frances A. Fuller Family Trust) by him in order to (i) cause the
election to the Board of Directors of the Company the designee of the Fund, (ii)
cause the removal from the Board of Directors (with or without cause) of any
director elected in accordance with clause (i) upon the written request of the
Fund, and upon the vacancy in the Board of Directors as a result of any
individual designated as provided in accordance with clause (i) above ceasing to
be a member of the Board of Directors, whether by resignation or otherwise, the
election to the Board of Directors as promptly as possible of any individual
designated by the Fund that is reasonably acceptable to the Company.
Additionally, the Fund is granted tag-along rights, subject to certain
exceptions, in the event the Reporting Person transfers 15% or more, in the
aggregate, of the shares of Class A Common Stock or Class B common stock, par
value $.01 per share (the "Class B Common Stock") directly owned by him which,
for purposes of the tag-along rights, include shares owned by the Estate of
Frances A. Fuller (until distributed in accordance with Section 2(f) of the
Letter


                                     3 of 7




Agreement), but exclude shares owned by the Overlook Estate Foundation, Inc. or
the Frances A. Fuller Family Trust, in a single or series of related private
transactions.

         As previously reported, the Fund has also entered into a Registration
Rights Agreement between the Company and the Fund, dated December 12, 2000 (the
"Registration Rights Agreement"), pursuant to which the Company has agreed,
under the terms and conditions set forth therein, to register under the
Securities Act of 1933, as amended, the Class A Common Stock issuable upon the
conversion of the shares of Preferred Stock held by the Fund and all other
shares of Class A Common Stock held by the Fund.

         Copies of the Letter Agreement, the Stock Purchase Agreement, the
Registration Rights Agreement and the Certificate of Designation of 4.0% Senior
Redeemable Convertible Preferred Stock, Series A have previously been filed with
the Securities and Exchange Commission as exhibits to a Current Report on Form
8-K filed by the Company on December 20, 2000 and are incorporated therein by
reference.

Item 4.  Purpose of Transaction

         To the knowledge of the Reporting Person, the Fund acquired the
securities of the Company for investment purposes only. The Reporting Person may
from time to time acquire additional shares of Class A Common Stock in the open
market or in privately negotiated transactions, subject to the availability of
shares of Class A Common Stock at prices deemed favorable, the Company's
business or financial condition and to other factors and conditions the
Reporting Person deems appropriate. Alternatively, the Reporting Person may sell
all or a portion of the shares of Class A Common Stock or Class B Common Stock
in open market or in privately negotiated transactions, subject to the factors
and conditions referred to above and compliance with applicable laws. Pursuant
to the Letter Agreement, the Company agreed to cause the Fund's nominee to be
appointed to the Company's Board of Directors on or prior to January 11, 2001,
and such nominee currently is T. Michael Long, a co-manager of the Fund.

         Except as set forth in this Item 4, the Reporting Person does not have
any present plans or proposals which would relate to or would result in: (a) the
acquisition by any person of additional securities of the issuer, or the
disposition of securities of the issuer; (b) an extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving the
company or any of its subsidiaries; (c) a sale or transfer of a material amount
of assets of the Company or of any of its subsidiaries; (d) any change in the
present Board of Directors or management of the Company, including any plans or
proposals to change the number or term of directors or to fill any existing
vacancies on the board; (e) any material change in the present capitalization or
dividend policy of the Company; (f) any other material change in the Company's
business or corporate structure; (g) changes in the Company's charter, bylaws or
instruments corresponding thereto or other actions which may impede the
acquisition or control of the Company by any person; (h) causing a class of
securities of the Company to be delisted from a national securities exchange or
to cease to be authorized to be quoted in an inter-dealer quotation system of a
registered national securities association; (i) a class of equity securities of
the Company become eligible for termination of registration pursuant to Section
12(g)(4) of the Securities Exchange Act of 1934, as amended; or (j) any action
similar to any of those enumerated above.

         On November 26, 2001, the Company filed a definitive information
statement on Form 14C with the Securities and Exchange Commission disclosing its
intent to file an amendment to its Restated Certificate of Incorporation
increasing its authorized shares of Class A Common Stock to 30,000,000 and its
authorized shares of Class B Common Stock to 5,000,000. The Company filed that
amendment with the Secretary of State of the State of Delaware on December 17,
2001.

                                     4 of 7



         In connection with the closing of a public offering of 2,575,000 shares
of Class A Common Stock by the Company on December 21, 2001, the Reporting
Person sold 250,000 shares of Class A Common Stock pursuant to an Underwriting
Agreement dated December 17, 2001 by and among the Company, the Reporting
Person, Louis S. Fuller, Credit Suisse Fist Boston Corporation, ABN AMRO
Rothschild LLC, Bear Stearns & Co., Inc., Morgan Keegan & Company, Inc. and BB&T
Capital Markets, a division of Scott Stringfellow, Inc. The purpose of the sale
made by the Reporting Person was to (1) repay a loan associated with the
exercise of options to purchase shares of the Company, and (2) diversify the
Reporting Person's portfolio.

Item 5.  Interests in Securities of the Issuer

         (a)-(c) The beneficial ownership of the Company's Class A Common Stock
by the Reporting Person is as follows:

        The Reporting Person beneficially owns 965,640 shares of Class A Common
Stock, 658,069 of which are represented by shares of Class B Common Stock that
are convertible into shares of Class A Common Stock at any time, 2,775 of which
are represented by shares owned by the Reporting Person's wife, as to which
shares the Reporting Person disclaims beneficial ownership, 21,332 of which are
represented by shares owned by Overlook Estate Foundation, Inc., of which the
Reporting Person is President, 18,750 of which are represented by options to
purchase shares of Class A Common Stock which will become exercisable on January
30, 2002 and 264,714 of which are represented by presently exercisable
third-party options to purchase shares of Class B Common Stock. Such beneficial
ownership represents 8.5% of the outstanding shares of Class A Common Stock
(assuming the conversion of outstanding shares of Class B Common Stock to Class
A Common Stock and the conversion of the Preferred Stock into 1,632,539 shares
of Class A Common Stock).

        The Reporting Person's beneficial ownership set forth above excludes
the 1,632,539 shares of Class A Common Stock beneficially owned by the Fund
Group which he may be deemed to beneficially own pursuant to Rule 13d-5(b)(1).

        The Fund Group beneficially owns 1,632,539 shares of Class A Common
Stock, excluding the 965,640 shares, which they may be deemed to own
pursuant to Rule 13d-5(b)(1), representing 14.4% of the outstanding shares
of Class A Common Stock (assuming the conversion of outstanding shares of
Class B Common Stock to Class A Common Stock and the conversion of the
Preferred Stock into 1,632,539 shares of Class A Common Stock). Therefore,
for purposes of Rule 13d-5(b)(1), the group comprised of the Fund Group and
the Reporting Person beneficially own 2,598,179 shares of Class A Common
Stock, representing 22.9% of the outstanding shares of Class A Common
Stock.

        The Reporting Person has sole power to vote and dispose of 962,865
shares of Class A Common Stock, 658,069 of which are represented by shares of
Class B Common Stock that are convertible into shares of Class A Common Stock at
any time, 21,332 of which are represented by shares owned by Overlook Estate
Foundation, Inc., of which the Reporting Person is President, 18,750 of which
are represented by options to purchase shares of Class A Common Stock, which
will become exercisable on January 30, 2002, and 264,714 of which are
represented by presently exercisable options to purchase shares of Class B
Common Stock. The Fund Group has sole power to vote and dispose of 1,630,436
shares of Class A Common Stock.

        In connection with the offering described in Item 4 above, the
Reporting Person (1) exercised options to purchase 84,374 shares of Class A
Common Stock and (2) converted 64,641 shares of the Company's Class B Common
Stock, par value $.01 per share, into 64,641 shares of Class A Common Stock.
These 149,015 shares of Class A Common Stock were sold by the Reporting Person
in the offering.

        Prior to the closing of the public offering, the Reporting Person made
a charitable gift of 15,000 shares of Class A Common Stock.


                                     5 of 7





         Except as set forth above, no party described in this Schedule 13D
beneficially owns any shares of Class A Common Stock or has effected any
transaction in shares of Class A Common Stock during the preceding 60 days.

         Paragraphs (d) and (e) of Item 5 of Schedule 13D are not applicable to
this filing.
