There had been many discussions over the future of the company in the second review period, and it was announced on 7 May 2010 that Transport for London had agreed to buy the shares of Bechtel and Amey (Ferrovial) from Tube Lines for £310m.

Amey continues to provide TfL with management and maintenance services for the Jubilee, Northern and Picadilly lines.
