On 23 October 2000, Winsor announced a new regulatory financial settlement of £14.8 billion for Railtrack for the five years 2001-2006 This represented a 50% increase over the settlement for the previous regulatory control period, 1995-2001. This was the culmination of a regulatory review of the company's asset maintenance and management plans, and the demands which passenger and freight train operators were likely to make of the network in the future. Railtrack's poor asset knowledge hampered the work. The fact that the company's information—and that of the Office of the Rail Regulator in the past—was so unsatisfactory frustrated Winsor.
