As part of the upgrade at Bristol Parkway, Network Rail are undertaking track improvements around Filton, Cardiff and Bristol Temple Meads.
During October and November weekends, diversions will be in place and buses will replace some services. On October 15, 22 and 29, some trains between London and South Wales will terminate at Bristol Parkway, with replacement buses running between Bristol Parkway and Cardiff Central.
Three weekend closures have been planned at Bristol Parkway in November (4/5, 11/12, 18/19). Trains will not call at the station during these three weekends. Diversions will be in place and replacement buses running instead of trains for some journeys.
