Portishead railway station was opened by the Bristol and Portishead Pier and Railway in 1867; it was approximately 0.5 miles (0.80 km) from the town of Portishead, North Somerset, England. After the opening of the Pier in 1870, the line was extended with an additional railway station opened by the pier. The Pier station closed first; and the original Portishead station closed in 1954, with a new Portishead station opened nearer the town. The 1954 station closed in 1964 when passenger services were withdrawn from the line.

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.
