EX-99.1

DALLAS – May 3, 2005 – Trinity Industries, Inc. (NYSE:TRN) today reported financial results for the three months ended March 31, 2005.

For the quarter ended March 31, 2005 the Company reported earnings of $6.0 million, 11 cents per common diluted share, and revenues of $647 million. This compares with a net loss of $10.8 million, 25 cents per common diluted share, and revenues of $455 million in the same quarter of 2004. The first quarter of 2005 included an after-tax provision of approximately $2.1 million (4 cents per diluted share) related to the proposed settlement of two lawsuits and two other non-related warranty issues in the Company’s Inland Barge Group. The first quarter of 2004 included an after-tax loss provision for $4.8 million (10 cents per diluted share) due to the effect of cost increases in steel and components containing steel on certain rail and barge contracts as well as an after-tax charge of $769,000 (2 cents per diluted share) related to the early retirement of debt.

“I’m very pleased with our first quarter progress,” said Timothy R. Wallace, Trinity’s Chairman, President and CEO. “Our first quarter consolidated revenues increased 42% over last year, resulting in a profitable quarter—despite rising steel costs and legal settlement charges. The initiatives that we put into place during the past year are starting to produce results.”

“We turned a major corner during the first quarter from an operating performance and profitability point of view. Our revenues and operating results improved this quarter over the same period last year in each of our five business groups. I am very proud of our employees’ team efforts to accomplish these results.”

“Trinity’s North American railcar unit shipments were 5,300, an 89 percent increase over the same quarter last year, and the highest quarterly shipment level since the first quarter of 2000.”

“Our railcar shipments in North America have become consistent. Our North American railcar revenues increased 112% over last year reflecting higher prices as well as increased unit volume. We expect improved year over year performance each quarter in 2005,” Wallace said. “In addition, construction-friendly March weather resulted in a strong first quarter for our construction-related businesses.”

During the first quarter, Trinity also completed an increase and extension of its revolving credit facility to $350 million for five years. As of March 31, 2005, Trinity had no borrowings against this facility. “The completion of this facility gives Trinity increased flexibility to grow and expand as the recovery continues,” Wallace said. “It also underscores the strong reputation Trinity has developed in the debt capital market.”
