FOR RELEASE: IMMEDIATE

GATX CORPORATION REPORTS 2007 FOURTH QUARTER AND FULL-YEAR RESULTS; BOARD OF DIRECTORS AUTHORIZES $200 MILLION SHARE REPURCHASE PROGRAM

	•		Income from continuing operations of $3.08 per diluted share in 2007, excluding tax benefits
	•		Company expects 2008 income from continuing operations to be in the range of $3.15 — $3.35 per diluted share

          CHICAGO, January 24 - GATX Corporation (NYSE:GMT) today reported 2007 fourth quarter and full-year results. In the 2007 fourth quarter, income from continuing operations was $41.4 million or $.81 per diluted share compared to $28.7 million or $.51 per diluted share in the fourth quarter of 2006. Income from continuing operations for the full-year 2007 was $185.8 million or $3.44 per diluted share, compared to $151.4 million or $2.65 per diluted share in the prior year.

          The 2007 and 2006 GAAP fourth quarter and full-year results were impacted by certain tax benefits. Excluding tax benefits, 2007 fourth quarter income from continuing operations was $31.6 million or $.62 per diluted share compared to $28.7 million or $.51 per diluted share in the fourth quarter of 2006. Excluding tax benefits, income from continuing operations for the full-year 2007 was $165.7 million or $3.08 per diluted share compared to $145.5 million or $2.55 per diluted share in the prior year.

          A summary of 2007 and 2006 fourth quarter and full-year results, detailing the tax benefits and including discontinued operations, is included in this press release on page 14.

          Highlights for the 2007 fourth quarter and year include:

	•		Utilization of Rail’s North American fleet closed the year at 97.9%, unchanged from the third quarter 2007, and lease renewal success remained high throughout the year.
	•		In the fourth quarter, on a basket of common car types, lease renewal rates increased 12% over expiring rates and the average renewal term was 69 months.
	•		European rail operations continued to improve in 2007. Fleet utilization on the wholly-owned European fleet was 97.2% at year end versus 95.5% at the end of 2006.
	•		American Steamship Company (ASC) experienced strong demand throughout the year, but poor weather and lower water levels hurt operating results.
	•		Specialty reported another strong year, as marine joint ventures continued to experience near-record charter rates.

Page 2

	•		Remarketing income at GATX reached record levels, indicative of very strong asset values throughout 2007. Rail’s significant remarketing income also reflects the Company’s proactive fleet optimization strategy.
	•		Investment volume totaled $641 million in 2007, with volume in the fourth quarter the strongest experienced during the year at $216 million.

          “GATX achieved excellent financial results in 2007,” said Brian A. Kenney, president and chief executive officer. “Excluding tax benefits, income from continuing operations increased 14% from 2006, return on equity was 14%, we grew assets across our businesses in a competitive market, and we positioned the Company to capitalize on the rail market downturn.

          “In Rail, lease income increased as we renewed leases at higher-than-expiring rates, we acquired 6,000 cars for the North American fleet, we expanded our locomotive fleet, and we continued to invest in our market-leading railcar platform in Europe.

          “In Specialty, our marine joint ventures achieved excellent results as charter rates remained near historical highs. We also capitalized on attractive asset prices through sales of certain owned and affiliate-owned assets, which produced record remarketing income in 2007.

          “In addition to producing excellent financial performance in 2007, we spent the last few years preparing the Company to take advantage of the inevitable down cycle in our core rail market. For instance, we sold a volatile and underperforming Air business, we sold targeted rail assets into a strong market, we dramatically extended lease renewal terms at attractive rates and we diversified further into the improving European rail market – all while substantially improving our balance sheet and cost of funds. On the investment side, we have executed a disciplined strategy. For instance, we used our Committed Purchase Program to acquire and place railcars at an attractive and advantaged cost relative to competitors. We also refrained from placing large, speculative new car orders, choosing instead to preserve our purchasing power for opportunities where railcar acquisition costs are more attractive for GATX. Our recent new car order is an early indication that railcar acquisition costs have started to move in GATX’s favor.”

          Mr. Kenney continued, “As a result of these steps, we are looking forward to 2008 – despite the prospect of a deteriorating economy. In Rail, our success in extending average lease terms has dramatically reduced the number of expiring leases in 2008 compared to previous years, lowering our near-term exposure to the weaker rail market. We expect Rail’s 2008 segment profit to decline marginally versus 2007. Higher maintenance costs and intentionally lower remarketing income are expected to be partially offset by strong performance in Europe. Importantly, we are more optimistic

Page 3

about our ability to add railcar assets to our portfolio at attractive prices, building substantial long-term value for our shareholders.

          “In Specialty, we are also expecting 2008 segment profit to decline marginally versus 2007, as reduced scheduled remarketing events will cause remarketing income to be lower than the record levels in 2007. However, the overall operating environment for our marine joint ventures, Rolls-Royce engine leasing joint venture and our industrial equipment investment activity is expected to remain positive. At ASC, 2008 segment profit is expected to increase versus 2007, based on the assumption that shipping contracts continue renewing at increasingly higher rates and operating conditions improve.

          “Our Board of Directors has authorized a $200 million share repurchase program. This authorization enables GATX to capitalize on an attractive valuation opportunity in our stock while also providing the continued flexibility to invest in rail, marine, and industrial equipment assets.

          “Although we anticipate a modest decline in consolidated segment profit in 2008, EPS is expected to be in the range of $3.15 — $3.35 per diluted share, reflecting the positive impact of GATX’s share repurchase activity as well as the strength of our underlying asset base and the diversity of our operating activities.”

          Mr. Kenney concluded, “Obviously, despite the steps taken over the last few years to reduce volatility, GATX’s results are not immune to a sustained economic downturn. Our 2008 earnings outlook assumes a broadly weakening rail market. However, a more severe economic environment or more aggressive competitor behavior would have a negative impact on our Rail fleet utilization and 2008 results. Additionally, even with 110 years of operating history, predicting how long a rail downturn will last is an inexact science. Clearly, a longer decline has a more material impact on results. Regardless, the Company is well positioned to weather market uncertainty and is uniquely positioned to capitalize on resulting investment opportunities.”

RAIL

          Rail reported segment profit of $63.5 million in the fourth quarter of 2007, comparable with the fourth quarter of 2006. Rail reported segment profit of $267.3 million for the full-year 2007, compared to $247.9 million in 2006. Segment profit increased year over year primarily due to an increased number of cars on lease, higher average lease rates, improved contributions from European operations, and increased remarketing income.

Page 4

          At December 31, 2007, Rail’s North American fleet totaled approximately 112,000 cars and fleet utilization was 97.9%, flat with the third quarter 2007 and down from 98.5% at year end 2006. The North American active fleet increased by nearly 1,300 cars over year end 2006.

          Maintenance expense rose considerably in the fourth quarter and full-year 2007, reflecting a larger active fleet, an acceleration in the volume and cost of repairs completed by railroads, and increased compliance work.

          During the fourth quarter, lease renewal pricing on a basket of Rail’s most common car types increased 12% over expiring lease rates, compared to a 17% increase in the prior quarter. Rail extended the average term on basket renewals during the fourth quarter to 69 months, compared to 70 months in the fourth quarter of 2006. For the full-year 2007, lease renewal rates increased 16% over expiring rates with an average renewal term of 72 months. This compares with an average renewal rate increase of 14% and average renewal term of 68 months in 2006.

          Investment volume in the fourth quarter totaled approximately $175 million in 2007 versus approximately $217 million in the fourth quarter 2006. Full-year investment volume totaled $494 million in 2007 compared to $534 million in 2006. Rail acquired approximately 6,000 cars for its North American fleet during 2007, comprised of 3,200 new and 2,800 used railcars, and sold or scrapped over 4,000 cars. Many of the new railcars were acquired at advantaged prices through our Committed Purchase Program, which was completed at the end of 2007. Additionally, Rail’s success in acquiring used railcars and locomotives is a result of a proactive initiative to target certain used asset types. Rail also identified additional attractive investment opportunities in Europe, investing more than $90 million in this important market.

          In macroeconomic data related to Rail’s business, North American manufacturing capacity utilization, as reported by the Federal Reserve, was 81.4% in December 2007, down from 81.6% at the end of 2006. Carloadings on the U.S. rails, excluding intermodal, as reported by the Association of American Railroads, decreased 2.5% over 2006, primarily due to lower demand for building products related to housing. Chemical shipments increased 3.3% in 2007 versus 2006.

SPECIALTY

          Specialty reported segment profit of $19.1 million in the fourth quarter of 2007, compared to $13.1 million in the prior year period. For the full-year 2007, Specialty reported segment profit of $117.5 million, compared to $98.9 million in 2006. The 2007 and 2006 year-to-date results reflect very strong remarketing activity. Vessel utilization in Specialty’s marine investments remained high in 2007, as demand strengthened and charter rates increased.

Page 5

          Specialty invested $141 million in 2007, primarily in industrial and marine equipment. The Specialty portfolio currently consists of approximately $521 million of owned assets (including on and off balance sheet assets) and third-party managed portfolios totaling approximately $378 million.

AMERICAN STEAMSHIP COMPANY

          American Steamship Company (ASC) reported segment profit of $1.8 million in the fourth quarter 2007, compared to $8.2 million in the fourth quarter 2006. Full-year 2007 segment profit was $20.7 million, compared to $32.0 million in 2006. Inclement weather, particularly during the fourth quarter, led to significantly increased vessel delays and fewer operating days on the Great Lakes in 2007 compared to 2006. In addition, 2007 results include winter maintenance expense on the six vessels acquired in June 2006. These costs were excluded from ASC’s operations in 2006 due to the timing of the acquisition.

DISCONTINUED OPERATIONS

          In the third quarter of 2006, GATX signed an agreement to sell the majority of its aircraft leasing business to Macquarie Aircraft Leasing Limited (MALL). As a result, the aircraft leasing segment is reported as discontinued operations and prior periods have been restated to conform to the current presentation. The sale of the wholly-owned aircraft was completed on November 30, 2006 and the sale of the interests in joint venture aircraft was completed on January 17, 2007.

          In addition to the sale to MALL, GATX sold 27 aircraft to AerCap in the latter half of 2006, and in July 2006 completed the sale of GATX’s share of the Pembroke joint venture to Pembroke management.
