§ Mr. CohenTo ask the Secretary of State for the Environment, Transport and the Regions, pursuant to his answer of 3 July 2000,Official Report, column 84W, if he will specify the problems with the final trainborne element of the Automatic Train Operation signalling system; and if he will make a statement. [131366]
§ Mr. HillThere are two faults which have developed: stopping inaccuracy and overrunning platforms. Almost all station stops are now to specification. Minor stopping inaccuracy no longer causes significant service delay.
The problems with ATO arise from the train failing to register the station properly and overrunning the station platform. Although this creates no safety risk, it causes disruption for customers and the timetable.
The Central Line should be fully ATO operational by the end of the year subject to HMRI approval.
