Ministers emphasised the importance of a special £400m 'performance fund' available to both the passenger train operating companies and Railtrack which, from April, will be available to keep the services running on time. This will be used to provide immediate aide for the operators should another unforeseen crisis, such as the problems over cracked and broken rails which followed the Hatfield disaster, threaten to ruin the timetable. The rail plan itself is four months late arriving and has been overshadowed by a series of strikes and poor performance by the passenger train companies, particularly those serving London's busy commuter routes.
