This study (formerly known as the London to Reading Study) was commissioned in July 2001 by Government Office for the South East (GOSE) and undertaken by a consortium of consultants led by WS Atkins. The final report was completed in January 2003 and handed over to the Assembly for consideration. Details of the study, including the final report can be found on the GOSE website.

The consultants' recommendations were considered at the 2 April Regional Planning Committee meeting, and the Executive Committee at its 11 April meeting. The formal response was agreed and sent to the Secretary of State on 23 April 2003.
