TTX Company keeps the railroad industry in the US and Canada chugging along by leasing railcars. Rail companies generally prefer to rent railcars as needed rather than buy them because the cars are often switched and traded along the tracks. With 127,000 railcars, TTX's fleet includes three types of railcars (intermodal, autorack, and general use) designed to carry containers, autos, farm and construction equipment, and lumber and steel products. It has distribution centers in Illinois and Washington and maintains its fleet through three repair centers (in California, Florida, and South Carolina) and 31 inspection centers in the US. TTX is owned by the largest railroads in the US and Canada.
