Winsor's focus was on Railtrack, which he regarded as performing most unsatisfactorily. He criticised it for 'policies of neglect of its assets and hostility to its customers'. In his first month in office he took enforcement action against it in relation to its performance. He threatened a maximum financial penalty of £42 million if it failed to improve its performance towards passenger train operators by 12.7% in the operating year 1999-2000. The penalty would be £4 million for each percentage point it missed. Railtrack eventually missed this target by 2.7% and was fined £7.9 million in December 2001. Railtrack criticised the penalty as 'the largest fine in corporate history' which it was not. But it did represent a significant hardening of regulatory approach to the one which the company had enjoyed under the previous regulator.
