The most recent major work commissioned by the Forum is a study undertaken by consultants SDG to identify the wider economic benefits of the scheme (see Wider Economic Benefits Study).

Previously, amongst its other activity, the Forum commissioned a major study ("Outline Business Case") from consultants Atkins. This was completed in early 2004 and confirmed the business and practical case for the scheme. Subsequently, the Forum was actively involved in studies undertaken during 2005 on behalf of the SRA (Strategic Rail Authority) and the Rail Division of the Department for Transport which reconfirmed the findings of the earlier work (see Reports & Publications).

A broad range of other commitments has included items as diverse as the publication of an information leaflet in 2004 - newly updated and republished in November 2007; a Parliamentary briefing/reception for MP's and Lords; many presentations to groups as diverse as London and local business organisations, rail enthusiasts, local authority and environmental groups; participation in a regional "Olympic Roadshow"; and engagement with EU organisations in Brussels.

During 2008 and beyond, the Forum will be engaging with the scheme promoters to see how best we may assist with moving the proposal forward to the anticipated TWA (Transport & Works Act) application.
