     This Amendment No. 2 (this “Second Amendment”) supplements the statement on Schedule 13D originally filed in paper format on May 28, 2002, as amended by Amendment No. 1 to Schedule 13D filed on December 29, 2005, by Jose F. Serrano Segovia, Ramon Serrano Segovia, Teresa Serrano Segovia, Promotora Servia, S.A. de C.V., a Mexican corporation (“Promotora”), and Servicios Directivos Servia, S.A. de C.V., a Mexican corporation (“Servicios”), relating to the Series A Shares, without par value (the “Series A Shares”), of Grupo TMM, S.A. (formerly Grupo Servia, S.A. de C.V.), a fixed capital corporation (sociedad anonima) incorporated under Mexican law (the “Issuer”). Teresa Serrano Segovia is no longer a member of the group with the other Reporting Persons within the meaning of Section 13(d)(3) of the Securities Act of 1933 (the “Act”). This Second Amendment is filed by Jose F. Serrano Segovia, Ramon Serrano Segovia, Promotora, and Servicios (collectively, the “Reporting Persons”) to disclose potential litigation with respect to the shares owned by the Reporting Persons. Except as set forth below, all previous Items are unchanged.

ITEM 2. Identity and Background

     Item 2(a) shall be supplemented as follows:

     This Second Amendment is filed jointly by the Reporting Persons. As of January, 2005, Teresa Serrano Segovia, who was previously a member of a group with respect to the Series A Shares of the Issuer owned by the Reporting Persons, is no longer acting as a group with the Reporting Persons within the meaning of Section 13(d)(3) of the Act.

Item 5. Interest in Securities of the Issuer

     Item 5 shall be supplemented as follows:

     On June 9, 2006, Argyll Equities, LLC (“Argyll”) filed Plaintiff’s Original Petition for Declaratory Judgment against Servicios relating to the pledged ADSs reported herein in the County Court of Law in Kendall County, Texas. On June 19, 2006, Servicios filed an Original Answer, Counterclaims, and Application for Temporary Restraining Order and Injunctive Relief (the Counterclaims”) against Argyll in the same court relating to the pledged ADSs reported herein. In the Counterclaims, Servicios asserts several causes of action relating to Argyll’s calculations of the loan repayments and failure to maintain the safe custody of the collateral and for expedited discovery. On June 19, 2006, the Honorable Judge Bill R. Palmer, presiding over such court, ruled in favor of Servicios granting expedited discovery and a Temporary Restraining Order against Argyll, as attached in Exhibit 99.26 hereto which is incorporated by reference herein. Argyll’s counsel repeatedly stated to the court that Argyll intends to fully perform its contractual obligations to Servicios.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

     This Item 6 shall be supplemented as follows:

     As of June 26, 2006, an aggregate of 20,794,515 Series A Shares (including Series A Shares that may be represented by ADSs) owned by the Reporting Persons were pledged for the benefit of their creditors pursuant to certain of the pledge agreements attached as exhibits hereto, including but not limited to the pledge agreements attached hereto as Exhibits 99.27 and 99.28, which are incorporated by reference herein.

Item 7. Material to be Filed as Exhibits

     Item 7 shall be supplemented as follows:

Exhibit 99.26      Temporary Restraining Order, dated June 19, 2006.

Exhibit 99.27      Securities Pledge Agreement, dated June 21, 2006 by and between Servicios Directivos Servia, S.A. de C.V. and Banco Invex, S.A., Institucion de Banca Multiple, Invex Grupo Financiero.
