Greengauge 21 is a not-for-profit organisation which aims to research and develop the concept of a high speed rail network, and to promote its implementation as a national economic priority.
Founded by Jim Steer, one of the country's leading transport sector specialists, Greengauge 21 has been established to progress the debate on High Speed Rail and to promote it in the public interest. The organisation has been conceived as an umbrella under which all those with an interest in supporting and promoting a High Speed Rail network can come together and openly and publicly debate the merits of alternative routes, priorities and technologies, alternative implementation strategies and the economic and environmental benefits for Britain.
On this website you can find out more about Greengauge 21, read about the case for high speed rail and download our publications.
Consequences for Employment and Economic Growth: our latest research report sets out how HSR will enhance economic performance, create new jobs and generate a return to the exchequer.
Greengauge 21 will draw the attention of the wider public and business interests to the body of work that has already been carried out into High Speed Rail. We want to ensure that High Speed Lines are not subject to unnecessarily lengthy planning gestation periods because the problem is identifable now and the lead time is considerable for such a bold initiative. We also want to ensure that the enthusiasm of private promoters is not wasted in conflicting schemes that undermine the very idea we are all keen to promote.
