Description of Incident
Engineering work is taking place between Caerphilly and Rhymney, closing all lines from Saturday 19 July to Sunday 31 August (except Friday 1 August when lines are open for an event).
For the duration, when the lines are closed, buses will replace trains between Caerphilly and Rhymney, calling at all stations.
Background Information:
The Rhymney line is being upgraded as part of the next phase of the South Wales Metro. This six-week line closure is part of an intensive 8-month programme of engineering work on the upper Rhymney line, from Caerphilly to Rhymney.
The work taking place includes installing Overhead Line Equipment (OLE) to electrify the line, upgrading the track and signalling, and making station and infrastructure improvements. This will allow the introduction of brand-new tri-mode trains onto the Rhymney line, powered by electricity from the OLE, battery and diesel.
More information on this significant work is available on the Transport for Wales website.
