     TRINITY INDUSTRIES REPORTS OPERATING RESULTS FOR FIRST QUARTER OF 2003

         DALLAS - May 7, 2003 - Trinity Industries, Inc., (NYSE:TRN) today
reported financial results for the first quarter of 2003.

         For the quarter ended March 31, 2003, the company reported a net loss
of $14.5 million, or 32 cents per diluted share, on revenues of $289.1 million.
This compares to a net loss of $8.6 million, or 19 cents per diluted share, on
revenues of $384.3 million in the first quarter of 2002.

         "Even though our operating results for the 1st quarter are in line with
the guidance we provided at our last conference call, we are still not pleased
when we lose money," said Timothy R. Wallace, Trinity's chairman, president and
CEO. "The 1st quarter was full of a variety of challenges such as winter
weather, which affects our construction related businesses, a drastic drop in
the demand for barges, an unusual amount of uncertainty associated with the war
and a large portion of our railcar shipments going to customers in our leasing
company."

           "We do have encouraging news in our business. The North American
railcar industry backlog grew for the fourth consecutive quarter. Our market
share percentage for the 1st quarter for new orders slipped to the low 20's, but
we are pleased with our market




share for orders in the railcar types we are most focused on. Our market share
ranged from 40% to 73% on certain railcar models. The majority of our businesses
have all shown an improvement in their backlogs as well. Our barge business has
booked some very crucial orders which provide a base load. We continue to expect
to return to profitability during the 3rd quarter," Wallace said.

the nation's leading diversified industrial companies. Trinity reports five
principal business segments: the Trinity Rail Group, Trinity Railcar Leasing and
