Exhibit 99.1

		NEWS RELEASE

FOR RELEASE: IMMEDIATE

GATX CORPORATION REPORTS 2009 FIRST QUARTER RESULTS

     CHICAGO, April 23 - GATX Corporation (NYSE:GMT) today reported 2009 first quarter net income of $27.6 million or $.56 per diluted share, compared to net income of $51.8 million or $1.03 per diluted share in the first quarter of 2008. The 2009 first quarter results include a negative after-tax fair-value adjustment of $11.6 million or $.23 per diluted share related to certain interest rate swaps at GATX’s AAE Cargo affiliate, and the 2008 first quarter results include a $6.8 million or $.13 per diluted share after-tax benefit from the reversal of tax reserves.

     “We entered the year anticipating considerable challenges in our markets and operating conditions have been consistent with our expectations,” said Brian A. Kenney, president and chief executive officer of GATX. “In Rail, our customers are seeing decreased demand for their products and certain customers are operating under increasing financial stress. Consequently, there is pressure on fleet utilization and lease rates. Our North American fleet utilization was 96.5% at the end of the first quarter, down from 97.9% at year end and renewal lease rates on railcars in GATX’s Lease Price Index (LPI) declined 5.5%. Fortunately, the steps we took in recent years to position GATX for a downturn are helping us manage through these difficult market conditions.

     “As expected, the environment in Marine is also challenging. In Specialty, charter rates at the marine joint ventures declined significantly in the fourth quarter of 2008, and while they have increased in some markets, they remain weak compared to recent years. American Steamship Company (ASC) recently commenced its sailing season, and it is clear that continued idling of steel manufacturing capacity on the Great Lakes will result in significantly lower iron ore shipments during the year.”

     Mr. Kenney concluded, “Our 2009 full-year earnings estimate remains unchanged, excluding fair-value adjustments as noted above. There is increased downside variability to the estimate due to a variety of uncontrollable factors, which were noted in our 2008 year-end press release, including the price of scrap steel and other assets and increased financing costs that most companies face when accessing today’s capital markets. While the environment is volatile and difficult to predict, we remain focused on utilizing this uncertainty to strengthen our position in the market.”

RAIL

     Rail segment profit was $43.1 million in the first quarter of 2009, including the negative $14.3 million pre-tax impact of the fair-value adjustment of interest rate swaps at GATX’s AAE Cargo affiliate. Asset remarketing income and scrap gains (included in “Other income”) at Rail were materially lower in the first quarter of 2009 versus the prior year.

     At March 31, 2009, Rail’s North American fleet totaled approximately 112,000 cars. Fleet utilization declined to 96.5% from 97.9% at year end. The decline in utilization reflects both end-of-lease returns and the return of approximately 620 cars related to customer bankruptcies. Utilization and lease rate pressure is fairly broad based across car types, although it continues to be most acute in freight cars. The European wholly-owned tank car fleet totaled approximately 20,000 cars and utilization was 96.5% compared to 97.1% at year end.

     Additional current and historical fleet and operating data as well as macroeconomic data related to Rail’s business can be found on the last page of this press release.

SPECIALTY

     Specialty reported segment profit of $23.0 million in the first quarter of 2009 compared to $30.0 million in the prior year period. The year-over-year decline in segment profit was primarily due to lower share of affiliates’ earnings as the marine market remained soft following a sharp downturn in the fourth quarter of 2008.

     The Specialty portfolio currently consists of approximately $641.3 million of owned assets (including on and off balance sheet assets) and third-party managed portfolios totaling approximately $274.1 million.

AMERICAN STEAMSHIP COMPANY

     American Steamship Company (ASC) reported segment profit of $4.8 million in the first quarter 2009 compared to $.7 million in the first quarter 2008. ASC’s vessels are in winter lay up from January to late March. Steel mill capacity utilization and production are down dramatically from the prior year and ASC will deploy vessels accordingly. During the quarter, ASC reached a settlement in a litigation matter and as a result, recorded a $5.6 million recovery.
