As part of the work to electrify the line to Cardiff Bay, for two weeks starting this Saturday, 10th May, there will be no trains between Cardiff Queen Street and Cardiff Bay.

As well as electrifying and redeveloping the line to Cardiff Bay, Cardiff Bay Station is being redeveloped, and a new two-platform station is being built in northern Butetown.

During the closure, track will be installed into the new platform 2 at Cardiff Bay station, and platform 1, which is currently used for services between Cardiff Queen Street and Cardiff Bay, will be taken out of use until electrification of the Cardiff Bay line is complete.

From 26th May, there will be no access platform 1 at Cardiff Bay station from Bute Street, with access to the new platform 2 being transferred to the Lloyd George Avenue side of the station.

Whilst the Cardiff Bay line is closed, train tickets can be used at no extra cost on Cardiff Bus services. There will also be a few early morning and late night rail-replacement buses between Cardiff Queen Street and Cardiff Bay.

On Saturday, 18th May, there will be some rail-replacement buses running between Radyr and Cardiff Bay, but passengers should check their journey details before they travel at https://tfw.wales/plan-a-journey.

With the introduction of new electrically powered tram-trains and electrified lines being installed on the Core Valley Lines, Transport for Wales is reminding the public about the dangers of trespassing on the railway.

As well as being reckless, illegal, and dangerous, anyone caught trespassing is liable for a £1,000 fine. With the electrification work continuing over the coming months, the public is urged not to trespass and to stay clear of any electrical lines.

“The Bay Line transformation will see the biggest upgrade to public transport in the Butetown and Cardiff Bay area for a generation and is an important part of the South Wales Metro. This round of engineering works will be an important step in the project’s delivery, seeing us make headway on the development of a brand-new station in Butetown and the redevelopment of Cardiff Bay station. Teams will also be busy installing the new wires for the overhead line equipment during the line’s closure so that we can run the brand-new tram-trains. I d like to thank our customers and neighbours living near the railway for their patience as we carry out these works. Please check before you travel during this time.”
