. Rental car, black car/limo and rail spend can "account for as much as 10 percent of an organization’s overall travel program costs in the United States, and even more in areas of Europe and Asia Pacific where rail is a significant mode of transportation," according to CWT. Leading the practice is industry veteran Dave Kilduff, who joined CWT in April after a 21-year career with The Hertz Corporation.
