Business Model: BUY Railcar Supply Strategy GATX’s strategy is to secure railcars from a variety of sources as opposed to also being a railcar manufacturer; combining railcar manufacturing with a railcar leasing business: o Adds significant volatility leading to a higher cost of capital o Can result in poor asset allocation within the lease fleet as cars are added simply to optimize the manufacturing line GATX’s sources of railcar supply o Large, multi-year orders for new cars from manufacturers during the down cycle o Spot orders for new cars to meet specific customer demand o Fleet acquisitions of existing cars from other lessors and customers Benefits of railcar supply strategy o Access to attractively priced railcars o Ability to grow our high quality fleet and reliably meet customer demand 16

Business Model: MAXIMIZE VALUE GATX’s fleet of well-maintained modern railcars, leased to quality customers, allows us to realize significant remarketing income when we decide to sell cars in the secondary market. We also generate scrapping gains at the end of a railcar’s useful life.

GATX Rail North America: Engineering Expertise GATX’s engineering team, including experienced mechanical, structural, and chemical engineers, communicates regularly with customers and tailors solutions to meet their needs. AUTO CARRIER CONVERSION PROJECT ô GATX Engineering successfully converted older flatcars to auto carriers. Some of these flatcars were originally designed to carry over-the-road trailers and others were designed to carry standard containers (ISO Examples of engineering containers). This was an extensive end-to-end engineering project that support include: repositioned these cars into a more attractive market while also increasing their statutory lives from 50 years to 65 years. Preventative maintenance, Inspection plans, Car design / specifications, Chemical engineering, and customer-specific enhancements INCREASED GROSS RAIL LOAD PROJECTS ô These projects entail structural modifications to increase the gross rail load for existing, low-capacity cars. Doing so allows these cars to haul heavier loads and improves their marketability and acceptance by shippers/customers. 40
