The line through Filton Abbey Wood was due to have been electrified by 2017 as part of the Great Western Main Line electrification project, however this has been postponed indefinitely. The Cross Country Route, the Bristol to Exeter line and the Heart of Wessex Line were not set to be electrified, so services at Filton Abbey Wood would still have been provided by diesel trains; however many "Sprinter" units have been replaced by and "Turbo" units. The group Friends of Suburban Bristol Railways supports the electrification continuing beyond the main lines, as does MP for Weston-super-Mare John Penrose. The electrification scheme also included the four-tracking of the line through Filton to allow more services between and and to separate fast inter-city services from local stopping services, which was completed in November 2018. A fourth platform has been added in November 2018 as part of the project.
