                         Report of Independent Auditors

Board of Directors
Trinity Industries, Inc.

We have audited the accompanying statements of net assets available for benefits
of the Profit Sharing Plan for Employees of Trinity Industries, Inc. and Certain
Affiliates as Restated Effective April 1, 1999 as of December 31, 2001 and March
31, 2001, and the related statement of changes in net assets available for
benefits for the period from April 1, 2001 through December 31, 2001. 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 auditing standards generally accepted
in the 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 at
December 31, 2001 and March 31, 2001, and the changes in its net assets
available for benefits for the period from April 1, 2001 through December 31,
2001, in conformity with accounting principles generally accepted in the United
States.

1. DESCRIPTION OF THE PLAN

The following brief description of the Profit Sharing Plan for Employees of
Trinity Industries, Inc. and Certain Affiliates as Restated Effective April 1,
1999 (the Plan) is provided for general information only. Participants should
refer to the Summary Plan Description for a more complete description of the
Plan's provisions.

GENERAL

The Plan, as amended and restated, is a defined contribution plan designed to
comply with the provisions of the Employee Retirement Income Security Act of
1974 (ERISA) sponsored by Trinity Industries, Inc. (the Company).

Effective January 1, 2002, the Plan was amended to change the Plan Year to be
the calendar year, from January 1 through December 31 and to create a Short Plan
Year for the period from April 1, 2001 through December 31, 2001.

Fidelity Management Trust Company (Trustee) is the trustee and recordkeeper of
the Plan. The Company and the Trustee have entered into a Master Trust
Agreement. Under the Master Trust Agreement, the Plan participates in the
Trinity Industries, Inc. Master Trust (the Trinity Master Trust) with the
McConway & Torley Profit Sharing Plan (the M&T Plan). The Company is the plan
sponsor of the M&T Plan.

PARTICIPATION

Each employee of the Company is eligible to contribute to the Plan on the first
day of the month following 60 days of eligible employment, and must meet the
following additional requirements:

     1)   Must be classified as a full-time, part-time, or temporary employee of
          the Company; and

     2)   Must be in a unit of employees who are designated as eligible to
          participate in the Plan; and

     3)   Must not be included in a unit of employees covered by a collective
          bargaining agreement, unless benefits under this Plan were included in
          an agreement as a result of good faith bargaining.



                                                                               4

               Trinity Industries, Inc. and Certain Affiliates as

                    Notes to Financial Statements (continued)


1. DESCRIPTION OF THE PLAN (CONTINUED)

Eligible employees automatically become participants in the Plan and must
indicate on the form or forms provided by the Plan Committee (the Committee)
whether or not they want to make contributions to the Plan. If they elect to
contribute, they will authorize the Company to make payroll deductions to be
contributed to the Plan.

Effective October 26, 2001, any employee of Thrall Car Manufacturing Company or
Duchussois Industries, Inc. who, immediately prior to October 26, 2001, was a
participant in, or eligible to participate in, the Thrall Car Manufacturing
Company Salaried Employees' Retirement Savings Plan, the Thrall Car
Manufacturing Company Hourly Employees' Retirement Savings 401(k) Plan and the
Thrall Car Manufacturing Company Certain Illinois Hourly Employees' Retirement
Savings Plan (collectively the Thrall Plans), became eligible to participate in
the Plan.

CONTRIBUTIONS

Each participant electing to contribute to the Plan agrees to contribute not
less than 1% nor more than 14% of their eligible compensation, as defined by the
Plan, in 1% increments as designated by the participant. A salary reduction and
contribution agreement must be entered into by each employee as the employee
begins participation in the Plan, and may be amended at any time.



                                                                               5

                    Notes to Financial Statements (continued)


1. DESCRIPTION OF THE PLAN (CONTINUED)

Company matching contributions shall be made if Company earnings are at least
sufficient to pay dividends to stockholders ($0.54 per share for the period from
April 1, 2001 through December 31, 2001) but in no event less than $0.33 1/3 per
share of common stock. The Board may, in its sole discretion, elect to waive the
Company earnings requirement. If the Company matching contribution is made, then
each participant shall receive an amount equal to a percentage of that portion
of such participant's contribution, up to six percent of such participant's
total eligible compensation for the year, as defined, under the following
schedule:



                                                       PERCENTAGE OF COMPANY
                      YEARS OF SERVICE                     CONTRIBUTION

                  Less than 1 year                             0%
                  1 but less than 2 years                     25%
                  2 but less than 3 years                     30%

                  4 but less than 5 years                     40%
                  5 or more years                             50%


Company contributions are net of forfeitures, as defined. Company contributions
for a given Plan year shall be deposited in the Trinity Master Trust no later
than the date on which the Company files its federal income tax return for such
year.

PARTICIPANT ACCOUNTS

Participants may direct daily the investment of participant and Company
contributions among any of the thirteen registered investment companies and
Company common stock. Investments in Friede Goldman Halter, Inc. (formerly
Halter Marine Group, Inc.) common stock resulted from the divestiture of Halter
Marine Group, Inc. by the Company in 1997, when the Plan received 0.348 shares
of Halter Marine Group, Inc. common stock for each share of Company stock held
in the Plan, in the form of a tax-free distribution.



                                                                               6

1. DESCRIPTION OF THE PLAN (CONTINUED)

BENEFITS

Distribution of a participant's account balance is payable upon retirement at or
after age 65, total disability, death, or termination of employment.
Distribution is equal to the salary reduction contributions and related
earnings, plus the vested portion of any Company contribution and related
earnings.

Withdrawals of up to 100% of the participant's contributions can be made only to
meet "immediate and heavy financial needs" (medical care, college tuition, the
purchase of a principal residence, or to prevent the foreclosure on a principal
residence), as long as the funds are not available for such needs from other
sources. No withdrawals can be made against the earnings on the participant
contributions or against any Company contributions and related earnings. These
restrictions no longer apply when the participant reaches age 59 1/2.

Upon request, distributions shall be made no earlier than the later of the last
day of the calendar quarter in which entitlement occurs, or the date on which
the Committee determines the final balances. Distributions from the common stock
accounts shall be made in cash unless otherwise designated by the participant.

PARTICIPANT LOANS

Loans for "immediate and heavy financial needs" may be made for a minimum of
$1,000 up to a maximum of $50,000, not to exceed 50% of the participant's
contribution balance and related earnings plus 50% of the vested portion of the
Company contribution balance and related earnings. Loans are subject to rules
and regulations established by the Committee, as defined by the Plan.




                                                                               7

                  5 or more years                              100%


Participants are 100% vested in Company contributions and the allocated portion
of related earnings (losses) upon their attainment of age 65, and are always
100% vested in participant contributions and the related earnings (losses) on
such contributions.

ADMINISTRATION OF THE PLAN

who are appointed by the Board. The members of the Committee serve at the
discretion of the Board, and any Committee member who is an employee of the
Company shall not receive compensation for their services.

The expenses incurred by the Trustee in the performance of its duties, including
the Trustee's compensation and the services of the recordkeeper shall be paid by

1. DESCRIPTION OF THE PLAN (CONTINUED)

AMENDMENT OR TERMINATION OF THE PLAN

The Company may amend the Plan at any time. However, no amendment, unless made
to secure approval of the Internal Revenue Service (IRS) or other governmental
agency, may operate retroactively to reduce or divest the then vested interest
in the Plan of any participant, former participant or beneficiary, or to reduce
or divest any benefit payable under the Plan unless all participants, former
participants, and beneficiaries then having vested interests or benefit payments
affected thereby consent to such amendment.

The Company may terminate the Plan at any time, subject to the provisions of
ERISA. Upon complete or partial termination, the accounts of all participants
affected thereby shall become 100% vested, and the Committee shall direct the
Trustee to distribute the assets in the Trust Fund, after receipt of any
required approval by the IRS and payment of any expenses properly chargeable
thereto, to participants, former participants, and beneficiaries in proportion
to their respective account balances.

2. SIGNIFICANT ACCOUNTING POLICIES

BASIS OF ACCOUNTING

The financial statements of the Plan are prepared on the accrual basis of
accounting.

VALUATION OF INVESTMENTS

Investments in the Trinity Master Trust are valued at fair value. Investments in
registered investment companies are valued at published market prices which
represent the net asset value of shares held by the Plan at year-end.
Investments in common stock are stated at fair value based on quoted market
prices.



                                                                               9

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Purchases and sales of securities are recorded on a trade-date basis. Interest
income is recorded on the accrual basis. Dividends are recorded on the
ex-dividend date. Realized gains and losses from security transactions are
reported using average cost.

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
that affect the amounts in the financial statements and accompanying notes.
Actual results could differ from these estimates.

4. INCOME TAX STATUS

The Plan has received a determination letter from the IRS dated February 22,
2001, stating that the Plan is qualified under Section 401(a) of the Internal
Revenue Code (the Code) and, therefore, the related trust is exempt from
taxation. Once qualified, the Plan is required to operate in conformity with the
Code to maintain its qualification. The plan administrator believes the Plan is
being operated in compliance with the applicable requirements of the Code and,
therefore, believes that the Plan is qualified and the related trust is
tax-exempt.
