MetroWest, formerly known as the Greater Bristol Metro, is a project to improve the rail services in Bristol, England, and the surrounding region. It was first proposed at First Great Western's Stakeholder Event in March 2008. The aim of the project is to develop half-hourly services through central Bristol which will also serve the surrounding West of England region. Transport campaigning groups Friends of Suburban Bristol Railways (FoSBR) and Transport for Greater Bristol are actively supporting the proposal, as are the three unitary authorities under the West of England Combined Authority and North Somerset Council.
