To ask the Secretary of State for Transport which of the contractors responsible for rail safety in the (a) Paddington and (b) Hatfield rail crashes operated quality management systems. [105605]

I understand that Network Rail's safety procedures require contractors to have suitable and sufficient Safety Quality and Environment Management systems in place in accordance with the company's railway standards. Both Amey and Balfour Beatty had such systems in place at the times of the Paddington and Hatfield rail crashes.
