To ask the Secretary of State for Transport if he will make a statement on the recent occasions on which a train protection and warning system has been disabled. 
The Health and Safety Executive advise that, since April 2001, the Train Protection and Warning System (TPWS) has correctly operated and brought the train to a stop on 157 occasions. In none of these instances was the TPWS system disabled. However, on eight occasions the driver took action to reset the TPWS and continued forward without first contacting the signaller for authorisation, which is a contravention of the Rule Book. Action is being taken by the rail industry to rectify this type of driver behaviour.
