Railway upgrade works between Bridgend and St Fagans, Cardiff

Region & Route:: Wales & Western: Wales & Borders

Network Rail (Wales and Borders) is undertaking an essential programme of track renewal and maintenance work between Bridgend and St Fagans.

The works - which include renewing rails, sleepers, and stones under the track - are critical to maintaining the safety and reliability of the rail network. The work will involve a combination of day and night-time shifts to minimise disruption to passenger journeys as much as possible.

To allow teams to work safely and efficiently, St Fagans level crossing will be closed with a diversion in place for vehicles and pedestrians.

Saturday 21 June, 11pm until Monday 23 June, 6am
Saturday 5 July, 11pm until Monday 7 July, 6am

Please allow extra travel time.

During the works, some Great Western Railway (GWR) and Transport for Wales (TfW) services will be affected:

GWR trains will be diverted via Barry, extending journey times by up to 35 minutes and skipping stops between Bridgend and Cardiff.
A shuttle train service will operate between Swansea and Carmarthen.
Most GWR trains will depart earlier from Swansea, Neath, Port Talbot Parkway, and Bridgend.
TfW services will also be diverted via Barry.
A rail replacement bus service will run between Cardiff Central and Bridgend.

Thank you to passengers and residents for their patience while this important maintenance takes place.

About Network Rail

We own, operate and develop Britain's railway infrastructure; that's 20,000 miles of track, 30,000 bridges, tunnels and viaducts and the thousands of signals, level crossings and stations. We run 20 of the UK's largest stations while all the others, over 2,500, are run by the country's train operating companies.

Usually, there are almost five million journeys made in the UK and over 600 freight trains run on the network. People depend on Britain's railway for their daily commute, to visit friends and loved ones and to get them home safe every day. Our role is to deliver a safe and reliable railway, so we carefully manage and deliver thousands of projects every year that form part of the multi-billion pound Railway Upgrade Plan, to grow and expand the nation's railway network to respond to the tremendous growth and demand the railway has experienced - a doubling of passenger journeys over the past 20 years.
