On 2004 April 10 and 11 (Easter Saturday and Sunday) the line from Narroways Hill Junction to Filton Junction was closed to allow "further preparatory work... for the laying of a third track and the building of a new platform" at Filton Abbey Wood. Trains to and from Wales, and cross-country services through Bristol were diverted via Avonmouth and Henbury, adding about 11 miles (and an hour) to journeys.
