         "While the North American railcar market is still not showing signs of
recovery, we are pleased our other businesses are seeing signs of improvement.
We have good seasonal backlogs in our Construction Products Segment and our
Inland Barge backlogs are continuing to improve," said Timothy R. Wallace,
Trinity's Chairman, President and CEO.

         "We are continuing to reduce our overhead costs as our rail production
decreases. The steps we have taken over the last several months allow us to
stabilize our business as we continuously monitor the status of the industry's
demand for railcars. We believe long-term this industry will return to more
normal demand levels and we are positioned to respond quickly," Wallace said.

         Trinity Industries, Inc., with headquarters in Dallas, Texas, is one of
the nation's leading diversified industrial companies. Trinity reports five
principal business segments: the Railcar Segment, the Inland Barge Segment, the
Parts & Services Segment, the Construction Products Segment, and the Industrial
Products Segment. Trinity's web site may be accessed at http://www.trin.net.
