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.
