Treherbert Line Transformation
As we move forward with building the South Wales Metro, from 29 April 2023 to late January/early February 2024, we’ll be closing the railway from Pontypridd to Treherbert. this is so we can deliver our biggest programme of works to date.
The Treherbert line has some of the oldest equipment and infrastructure across the entire Core Valley Lines, dating back to early 1930’s. During this eight-month closure, we have a significant amount of work to do to modernise this section of railway.
Did you know?
Did you know the Treherbert line is currently operated by a Token Exchange Signalling System?
Token exchange in a railway is a physical object which a train driver is required to have or see, entering it into the token unit before travelling onto a particular section of single track. The token is endorsed with the names of the section it belongs to, i.e. Treherbert, Tonypandy.
This is the machine that operates the Treherbert line:
Our works include:
- Removing the old ‘Token Exchange Signalling System’ and installing a brand-new signalling system for the entire line.
- Diverting huge gas and water mains which are obstructing us from electrifying the railway.
- Installing equipment to allow trains to run using electricity, including foundation piling, and adding masts and wiring.
- New station platforms at Treherbert, Ynyswen and Dinas Rhondda.
- Building new track along the line and new passing loops between Ynsywen and Treherbert, Ton Pentre and Ystrad Rhondda, and Porth to Dinas Rhondda.
- New footbridge at Ynyswen and Dinas Rhondda.
- Level boarding at various stations.
- New and refurbished toilets, waiting rooms and shelters. We’re also installing or upgrading help points, CCTV cameras, ticket vending machines, smart ticket validators, Wi-Fi and customer information systems.
Bus replacement information
During these eight months, trains won’t be able to run unfortunately and we’re asking our passengers to check before travelling.
We’re running a rail replacement bus service throughout the Rhondda.
From Monday 5th June, our long-term Treherbert bus replacement plan will then start as per the below:
- A “core” timetable of one bus every 30 minutes, stopping at all stations.
- A “semi-express” AM and PM service for peak travel times. This will reduce journey times and add capacity.
- A dedicated school bus plan for Treorchy Comprehensive school.
- Our colleagues will be on hand at key locations to support our customers.
- We have extra vehicles available to respond to any operational or capacity issues as they arise.
- Rail replacement bus stops
- Rail replacement bus stop maps
We’ll continuously review this plan and amend as needed throughout these works.
To make it easier for our customers, we’ll have colleagues on hand at key locations, working closely between train and bus connections to offer help and advice when needed. There’ll also be enhanced wayfinding and signage at all stations and stops. Our journey checker tool will be updated with the replacement bus information.
We’re always looking at improving customer experience and your honest feedback on the survey will help us shape our rail replacement services in the future.
During the Treherbert Line Transformation, we’ll be offering 50% off the cost of travel for people living and travelling in the Rhondda. The offer will apply for journeys wholly on the Treherbert line and journeys between stations on the line and locations through to Cardiff Central.
Any customer who has a pre-existing ticket will be able to use the ticket on the replacement bus during the closure of the line.
Customers affected by this blockade, who live and travel between Treherbert and Trehafod are able to get a 50% off Rhondda Railcard which will be valid for travel during the period of disruption. For more information click here.
