A major railway station is set to be shut for three weeks as work is carried out to electrify the line between Bristol and London, BBC reports.
Trains will not call at Bristol Parkway while overhead wires are extended from Swindon to Patchway.
Parkway station is due to reopen on October 7.
Customers are being warned to expect disruption while the station - which serves some 2.5m passengers a year - is shut.
It is part of a £2.8bn scheme to bring electric trains to the Great Western mainline between London and south Wales.
During the engineering works, long distance services between London Paddington and Cardiff will call at the smaller Patchway station. A replacement bus service will operate between intermediate stations not served by trains.
