GATX Corporation is a leading global lessor of transportation assets, managing a fleet of over 150,000 railcars and tank containers. The company operates through three primary business segments: Rail North America, Rail International (encompassing operations in Europe and India), and Engine Leasing, which includes a joint venture with Rolls-Royce. Additionally, its Trifleet business manages tank containers leased to a diverse global customer base. GATX primarily provides full-service leases, meaning it maintains the railcars, pays ad valorem taxes and insurance, and offers other value-added services. By supplying critical capital equipment, the company enables customers in the petroleum, chemical, and agriculture sectors to transport their products efficiently without the burden of asset ownership and maintenance.
