                            Trinity Industries, Inc.
                   Notes to Consolidated Financial Statements
                                   (unaudited)
                               September 30, 2001


                                     General

The foregoing consolidated financial statements are unaudited and have been
prepared from the books and records of Trinity Industries, Inc. ("Trinity" or
the "Company"). In the opinion of management, all adjustments, consisting only
of normal and recurring adjustments necessary for a fair presentation of the
financial position of the Company as of September 30, 2001, the results of
operations for the six months and three month periods ended September 30, 2001
and 2000 and cash flows for the six month periods ended September 30, 2001 and
2000, in conformity with generally accepted accounting principles, have been
made. Because of seasonal and other factors, the results of operations for the
six-month and three-month period ended September 30, 2001 may not be indicative
of expected results of operations for the nine months ending December 31, 2001.
These interim financial statements and notes are condensed as permitted by the
instructions to Form 10-Q, and should be read in conjunction with the audited
consolidated financial statements of the Company included in its Form 10-K for
the year ended March 31, 2001. On September 13, 2001, the Board of Directors
approved to change Trinity's year-end to December 31 from March 31. The Annual
Meeting of Stockholder's will be held on May 13, 2002.


                                  Contingencies

The Company is involved in various claims and lawsuits incidental to its
business. In the opinion of management, these claims and suits in the aggregate
will not have a material adverse effect on the Company's consolidated financial
statements.

The Company has an interest bearing advance payment and deposit for inventory
purchases of approximately $44 million with a supplier who is under court
protection from its creditors. While management does not believe recovery of
this amount has been impaired, future operating results and restructuring of the
supplier could affect recovery.


                                 Unusual Charges

During fiscal year 2001, the Company recorded pre-tax charges of approximately
$173.3 million. The charges related to the restructuring of the Company's
railcar operations, investment and asset write downs, litigation reserves, and
other charges. $140.9 million of the unusual charges were charged to operating
profit. $32.4 million of the unusual charges were reported in Other expense
primarily for the write down of equity investments in fiscal 2001.

For the quarter ended September 30, 2000, the Company recorded pre-tax charges
of $51.9 million ($33.2 million after tax), or $0.88 per share. Of the $51.9
million, $44.1 million is included in cost of revenues, $4.8 million in selling,
engineering and administrative expenses, and $3.0 million in other expense.

Of the $173.3 million charges, $130.5 million were writedowns of existing assets
or, in the case of accrued expenses, reflected in such classification and, as of
September 30, 2001, $10.2 million of cash


                                       7


payments have been made. The remaining reserve of $31.8 million is detailed
below (in millions). Cash flow requirements of approximately $6 million are
expected to be paid over the next year and cash flow requirements for the
remaining liabilities, due to the nature of such liabilities, are currently
unknown.

                              Segments of Business

Trinity Industries, Inc. is a diversified industrial manufacturer. As of March
31, 2001, the Company modified its segment reporting to align the reportable
segments with current internal reporting. The Company combined the Highway
Construction Products segment and the Concrete and Aggregate segment into the
Construction Products segment, moved its Heads business into the Industrial
Products segment from Parts and Services, and moved its Deck Fittings and Marine
Parts business into the Inland Barge segment from Parts and Services.
Furthermore, the Company changed the definition of operating profit at the
segment level to include corporate shared services charges. Information
reflecting these changes for fiscal years 2001, 2000 and 1999 was presented in
the 2001 Annual Report in order to conform to these changes. The determination
of operating segments is based on the types of products and services provided by
the Company and the internal reporting relationships.

The new reporting format includes the following business segments: (1) the
Railcar segment, which manufactures and sells railcars; (2) the Inland Barge
segment, which manufactures barges and related products for inland waterway
services; (3) the Parts & Services segment, which manufactures and sells various
parts to manufacturers of railcars and other industrial products and provides
services such as railcar maintenance, fleet management, and leasing; (4) the
Construction Products segment, consisting primarily of highway guardrail and
safety products, concrete and aggregate, and girders and beams used in the
construction of highway and railway bridges; (5) the Industrial Products
segment, which manufactures and sells containers, container heads, weld fittings
used in pressure piping systems, and pressure and non-pressure containers for
the storage and transportation of liquefied gases and other liquid and dry
products. Finally, All Other includes transportation services, the Company's
captive insurance company, structural towers, and other peripheral businesses.

The financial information for the year-to-date and quarter ended September 30,
2001 and 2000 is shown in the tables below.

Effective April 1, 2001, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 133, as amended, "Accounting for Derivative Instruments
and Hedging Activities," which establishes a comprehensive standard for the
recognition and measurement of derivatives and hedging activities. Due to the
Company's limited use of derivatives, the impact was not material. In the first
six months of fiscal 2002, the Company entered into 7 interest rate swap
agreements with a total notional amount of $200.0 million in order to mitigate
the impact from interest rate fluctuations on outstanding debt obligations. The
Company pays an average fixed rate of 4.01% and receives a floating rate based
on the three-month LIBO rates. As of September 30, 2001, the fair value of these
swaps was recorded as a liability on the Company's books of ($ 4.3) million with
the offset to other comprehensive income.

Effective April 1, 2001, the Company adopted Statement of Financial Accounting
Standards No. 142, "Goodwill and Other Intangible Assets," (SFAS No. 142) which
requires that goodwill not be amortized but instead be tested for impairment
annually by reporting unit which is scheduled to be completed by the Company as
of December 31, 2001. The adoption of SFAS No. 142 is not expected to have a
material effect on the financial statements, however, the fair values of the
respective reporting units have not been finally determined. Recent developments
in the rail supply business could impact the valuation of goodwill related to
the acquisition of the Company's foundry business which specializes in
manufacturing railcar couplers and other components. For the six months ended
September 30, 2000, goodwill amortization was $1.4 million ($900 thousand after
tax or $0.02 per share). For the three months ended September 30, 2000, goodwill
amortization was $700 thousand ($400 thousand after tax or $0.01 per share). If
SFAS 142 had not been adopted goodwill amortization of approximately $1.8
million ($1.1 million after tax or $0.03 per share) would have been recorded for
the six months ended September 30,2001. Goodwill amortization of $1.0 million
($600 thousand after tax or $0.02 per share) would have been recorded for the
three months ended September 30, 2001.

During the six months ended September 30, 2001, the Company received total
proceeds of approximately $150 million pursuant to a sale-leaseback transaction
under a non-recourse-financing program to fund certain railcar leasing
activities. The net proceeds from the transaction were used to reduce the
Company's outstanding indebtedness. No revenue or profit was recorded at the
time of the sale-leaseback transaction. The related operating leases are
obligations of a bankruptcy remote, special-purpose corporation that is wholly
owned by Trinity but does not represent legal obligations of Trinity.

                                Subsequent Events

Thrall Merger

On October 26, 2001, the Company completed its merger transaction between a
subsidiary and privately owned Thrall Car Manufacturing Company ("Thrall").
Under terms of the agreement, Trinity paid $165 million in cash and issued 7.15
million shares of its common stock at the closing. In addition, Trinity has
agreed to make additional payments, not to exceed $45 million over five years,
based on a formula related to annual railcar industry production levels plus
certain amounts related to working capital balances at the closing date. The
purchase price will be allocated to the assets acquired and liabilities assumed
based upon estimated fair market values. The Company is currently in the process
of preparing the purchase price allocation and determining the useful lives of
the assets acquired. Results of operations for Thrall will be included with
those of the Company beginning after October 26, 2001. The cash portion was
funded by bank financing and is expected to be refinanced with long term debt.

Credit Facility

In October certain modifications were made to the company's committed revolving
bank facility to allow financing of the Thrall acquisition, establishing the
total available under the facility at $450 million. Amounts borrowed under the
facility bear interest at LIBOR plus 0.95% or other alternative rates at the
Company's option and can be converted to a one-year term loan on June 6, 2002.

         Item 2 - Management's Discussion and Analysis of Financial Condition
         and Results of Operations

                              Results of Operations

                 Six Months Ended September 30, 2001 Compared to
                       Six Months Ended September 30, 2000

Revenues for the first six months of fiscal 2002 decreased to $840.5 million
from $1,084.4 million primarily due to reduced car shipments in the Railcar
segment. Operating profit increased to $41.4 million compared to $22.6 million.
For the six months ended September 30, 2000, the Company recorded unusual
charges, included in operating profit, of $48.9 million. If these unusual
charges had not occurred, operating profit for the six months ended September
30, 2000 would have been $71.5 million. Such a decrease is mainly due to the
Railcar segment results.

Revenues for the Railcar segment decreased to $241.4 million from $452.8 million
while operating profit decreased to a loss of $0.1 million from a profit of $6.1
million. The decline in revenues and operating profit is a result of the
significant weakening in demand for new railcars in North America combined with
a


                                       11

higher percentage of railcar deliveries going to Trinity's lease fleet than in
the prior year. Prior year operating profit was affected by unusual charges of
$21.1 million. Operating margins declined as well due to sales price declines
and lower volumes.

Revenues for the Inland Barge segment decreased to $100.2 million from $103.3
million. Operating profit decreased to $5.0 million from $8.4 million. Unusual
charges of $3.7 million were recorded during the same period last year.
Competitive price pressures for both hopper barges and tank barges continue to
adversely affect operating profit.

Revenues decreased by $26.8 million in the Parts & Services segment, from $163.9
million (including intersegment sales of $28.7 million), to $137.1 million
(including intersegment sales of $34.8 million), while operating profit
increased to $15.3 million from $7.3 million. This decrease in revenues is
primarily due to the soft market conditions in the railcar market. The increase
in operating profit is due to the unusual charges of $6.2 million that were
recorded in the quarter ended September 30, 2000. This is in addition to prior
year operating losses associated with the Company's concrete mixer, concrete
batch plants and component parts for concrete related industries business which
was closed as of March 31, 2001.

Revenues for the Construction Products segment increased to $260.7 million from
$252.9 million, a 3.1% increase, while operating profit remained flat. The
increase in revenue is attributed to better weather conditions in the Concrete &
Aggregate business.

Industrial Products segment revenues decreased to $95.3 million compared to
$116.7 million. Operating profit increased to $3.9 million from a loss of $2.6
million. The reduction of revenues is primarily a result of reduced demand from
gas distributors in the Mexico LPG market. While this situation is not believed
to be long-term, it is uncertain as to when improvement will occur. The increase
in operating profit is due to the unusual charges of $6.5 million associated
with exiting the flange and valve business that was recorded in the quarter
ended September 30, 2000. In addition, improved margins for the US LPG business
contributed to the operating profit increase.

In the six months ended September 30, 2001, selling, engineering and
administrative expenses decreased to $82.5 million from $103.3 million in
comparison to the same period last year primarily due to headcount and other
cost reduction efforts. A total of $4.8 million of prior period unusual charges
was included in the selling, engineering and administrative expenses. During the
quarter ended September 30, 2001, the Company recorded non-rail related charges
of approximately $1.2 million primarily related to discontinuing the Company's
s-Venture subsidiary, which was formed to invest in service type companies, and
severance.

Net interest expense increased due to higher debt levels. The Company's
effective tax rate increased from 36% to 37.5% due to the impact of reduced
taxable income on available tax credits.

                Three Months Ended September 30, 2001 Compared to
                      Three Months Ended September 30, 2000

Revenues for the second quarter of fiscal 2001 declined to $372.9 million from
$550.7 million for the second quarter of fiscal 2000 primarily due to reduced
railcar shipments and related declines in railcar parts and services sales.
Operating profit increased to $18.8 million compared to a loss of $14.9 million.
In the quarter ended September 30, 2000, the Company recorded unusual charges,


                                       12


included in operating profit, of $48.9 million. If these unusual charges had not
occurred, operating profit for the three months ended September 30, 2000 would
have been $34.0 million.

Revenues for the Railcar segment decreased to $72.2 million compared to $238.7
million. Operating loss was $3.7 million compared to a loss $6.1 million for the
same period last year. Unusual charges of $21.1 million were recorded during the
same period last year. The decline in revenues and operating profit before
unusual charges is a result of the significant weakening in demand for new
railcars in North America combined with a higher percentage of railcar
deliveries going to Trinity's lease fleet than in the prior year. Operating
margins declined due to sales price declines and lower volumes.

Revenues for the Inland Barge segment decreased to $50.6 million from $51.7
million. Operating profit was $2.1 million compared to $1.9 million for the same
period last year. Unusual charges of $3.7 million were recorded during the same
period last year. The decrease in revenues and operating profit before unusual
charges is primarily due to reduced prices for both hopper barges and tank
barges.

Revenues decreased by $10.2 million in the Parts & Services segment, from $76.4
million (including intersegment sales of $13.8 million), to $66.2 million
(including intersegment sales of $15.6 million). Operating profit increased to
$7.1 million from a loss of $4.0 million. The decrease in revenues is primarily
due to the soft market conditions in the railcar market. The increase in
operating profit is due to the unusual charges of $6.2 million that were
recorded in the quarter ended September 30, 2000 and prior year operating losses
associated with the Company's concrete mixer, concrete batch plants and
component parts for concrete related industries business which was discontinued
last year.

Revenues for the Construction Products segment declined slightly due to material
cost reductions which were passed through to customers. Operating profit margins
were impacted by an increased proportion of revenues coming from lower margin
bridge sales.

Revenues for the Industrial Products segment declined to $51.3 million from
$57.6 million, primarily due to reduced demand from gas distributors in the
Mexico LPG market. Operating profit increased to $3.5 million from a loss of
$4.3 million for the same period last year primarily due to unusual charges of
$6.5 million associated with exiting the flange and valve business recorded in
the quarter ended September 30, 2000 and, to a lesser extent, improved margins
in the US LPG business.

In the quarter ended September 30, 2001, selling, engineering and administrative
expenses were $39.8 million compared to $54.1 million for the same period last
year primarily due to staffing and other cost reductions and unusual charges of
$4.8 million recorded in the quarter ended September 30, 2000. During the
quarter ended September 30, 2001, the Company recorded non-rail related charges
of approximately $1.2 million primarily related to discontinuing the Company's
s-Venture subsidiary, which was formed to invest in service type companies, and
severance.

                           Range of Expected Earnings

Prior to the decision to change the Company's year end and approval for the
closing of the Thrall merger on October 26, 2001, the Company had indicated the
expected range of earnings per share for the fiscal year ended March 31, 2002
was $0.80 to $1.00 per share. Presently, the range of expected earnings per
share for the nine months ended December 31, 2001 is $0.50 to $0.60 per share
excluding the effect of


                                       13

any restructuring charges related to the Thrall merger or other charges that may
be recorded in the quarter ending in December 2001. Presently, such charges are
expected to be in the range of $25 to $40 million or $0.37 to $0.59 per share
for the three month period.

                          Liquidity & Capital Resources

Net cash provided by operating activities increased to $87.9 million during the
first six months of fiscal 2002 compared to $58.9 million in the first six
months of fiscal 2001. Capital expenditures during the first six months of
fiscal 2002 were approximately $119.6 million of which approximately $97.5
million was for additions to the railcar lease fleet. This compares to $111.5
million of capital expenditures in the first six months of fiscal 2001 of which
$67.7 million was for additions to the railcar lease fleet. Proceeds from the
sale of property, plant and equipment (primarily lease fleet sales) were $139.1
million in the first six months of fiscal 2002 compared to $52.3 million in
fiscal 2001.

The Company presently has no intention to repurchase any additional shares. The
Company believes cash provided from operations and cash available under the bank
credit facility will be sufficient to meet its operating and capital expenditure
requirements for the remainder of the fiscal year. The Company believes
acquisitions could be financed through its bank credit facility and additional
borrowing with the consent of lenders.

                            New Accounting Standards

During the six months ended September 30, 2001, the Company received total
proceeds of approximately $150 million pursuant to a sale-leaseback transaction
with a non-recourse-financing program to fund certain railcar leasing
activities. The net proceeds from the transaction were used to reduce the
Company's outstanding indebtedness. No revenue or profit was recorded at the
time of the sale-leaseback transaction. The related leases are accounted for as
operating leases.

In June 2001, the Financial Accounting Standards Board issued Statement No. 141,
"Business Combinations" ("SFAS No. 141"). SFAS No. 141 eliminates the pooling of
interest method of accounting for business combinations. The company adopted
this statement on July 1, 2001. The adoption of SFAS No. 141 did not have a
material effect on the Company's financial statements.

Effective April 1, 2001, the Company adopted Statement of Financial Accounting
Standards No. 142, "Goodwill and Other Intangible Assets," (SFAS No. 142) which
requires that goodwill not be amortized but instead be tested for impairment
annually by reporting unit which is scheduled to be completed by the Company as
of December 31, 2001. The adoption of SFAS No. 142 is not expected to have a
material effect on the financial statements, however, the fair values of the
respective reporting units have not been finally determined. Recent developments
in the rail supply business could impact the valuation of goodwill related to
the acquisition of the Company's foundry business which specializes in
manufacturing railcar couplers and other components. For the six months ended
September 30, 2000, goodwill amortization was $1.4 million ($900 thousand after
tax or $0.02 per share). For the three months ended September 30, 2000, goodwill
amortization was $700 thousand ($400 thousand after tax or $0.01 per share). If
SFAS 142 had not been adopted goodwill amortization of approximately $1.8
million ($1.1 million after tax or $0.03 per share) would have been recorded for
the six months ended September 30,2001. Goodwill amortization of $1.0 million
($600 thousand after tax or $0.02 per share) would have been recorded for the
three months ended September 30, 2001.

                             Railcar Market Outlook

Based on current order activity, the Company believes that railcar industry
shipments for 2002 may be in the range of 15,000 - 20,000 units. At that level
of industry shipments, the Company may take additional restructuring charges and
would not expect to be profitable in the railcar segment.
