South Wales Metro: Further delays confirmed for railway upgrade
Further delays have been confirmed to upgrades to south Wales' commuter railway.
Known as the South Wales Metro, the £750m plans will see much of the valley line network electrified.
It was due to be finished by 2023 but the Welsh government now says the "majority" of the work will be finished by 2024.
It is not clear when the remaining work will be complete, with Covid and the rising costs of materials blamed.
News of the delay, first reported by ITV Wales, comes as the first electric lines were installed.

fW urged the public to stay clear of the new electrical lines, and said trespassers risked a £1,000 fine.
Leyton Powell, director of safety and sustainability, said: "Installation of the first electrical lines is a major step forward for us at TfW and once completed, this programme of works will provide greener transport for the future.
"However, it's fundamental that we highlight that electrification work is now underway and therefore the public must understand the risks and dangers.  
"As always, trespassing on the railway is dangerous and it's important that people obey the rules as they are for their own safety."

A Welsh government spokesman said: "Despite delays to the work on electrification of the Valleys lines mainly caused by the pandemic and global material supply constraints, progress is now being made at pace. 
"The new Stadler 231 trains are due to be introduced in January and the majority of work on the South Wales Metro scheduled for completion in 2024."
BBC Wales asked if the Welsh government was suggesting some of the work underway will be delivered later than 2024, but it did not comment further.
