Electrification of the Treherbert railway line
We’ll shortly be electrifying the Treherbert railway line, from Pontypridd to Treherbert station.
The overhead power lines that carry 25,000 volts will be ‘live’, making it extremely dangerous for any persons to come close to the overhead wires or any associated part of the structures. This includes the supporting masts, switch feeds and cables. The overhead power lines are always on, and you don’t need to touch them to be harmed or killed as the electricity can jump over 3 meters.
Whilst there is no danger to people using the railway correctly, anyone who does not respect the railway boundary, the fence line that protects both people and the operational railway from deliberate or accidental trespass, are placing themselves at risk.

More information on our No Second Chances OLE safety campaign can be found here.
Testing the Overhead Line Equipment (OLE)
As part of the energisation process, we will need to conduct two days of testing in May to ensure that the equipment across the Treherbert line is working properly.
The testing period will take place on Saturday 25 and Monday 27 May, with contingency plans in place for Sunday 26 May and Tuesday 28 May if required.
For the safety of the public during the testing period, we will need to close all public footbridges that cross the railway line, as well as station footbridges and the level crossing at Treherbert station on Saturday 25 and Monday 27 May.
The following footbridges will be closed to pedestrians on Saturday 25 and Monday 27 May. We will ensure pedestrians can still cross the railway line safely by either providing a suitable diversion route or a minibus shuttle service where needed.
- Rheola Road bridge
-
This bridge will be fully closed to pedestrians, with a minibus shuttle in place to transport pedestrians from either side safely. The shuttle bus will run 06:00 - 20:00 on Saturday 25 and Monday 27 May.

- Rhondda College footbridge
-
This bridge will be closed to pedestrians during the testing period.

Minibus shuttle service
To ensure pedestrians can still cross the railway safety whilst the footbridges are closed, we will be running three minibuses that will travel on a loop from 06:00 - 20:00 on Saturday 25 and Monday 27 May.
We will also have a fully accessible minibus on standby throughout the testing period. We will have staff stationed at each footbridge who will be able to request this minibus for you if needed.

To ensure that pedestrians can still cross other road bridges over the railway safely during this period we will have traffic management in place. This will help the public maintain a safe distance from the sides of the bridges. Please note the Rheola Road/A4233 overbridge will be closed for pedestrians during the testing period.
We will keep our social media channels up to date during the testing period and will communicate if any bridges are reopened earlier than expected or if any need to be closed for a longer period. You can follow us on X at @tfwrail to stay up to date.
Customers who have purchased season tickets with the Rhondda Railcard discount before Friday 31 May 2024 can continue to use the discounted ticket for its duration, otherwise no railcard discount is permitted on purchases after Friday 31 May 2024.
Extension of the Rhondda Railcard 50% discount
As a thank you to our customers and lineside neighbours for their patience throughout the transformation work, we will be extending the Rhondda Railcard discount scheme for 3 months following the reopening of the line in February 2024. The discount entitles all passengers who travel on the Treherbert line to a 50% discount on the cost of their ticket, with the discount available until the end of May 2024.
Ynyswen Station
Due to the extensive work that needs to be done to upgrade Ynyswen Station, the station will remain closed to allow our teams to continue to undertake significant work to the station.
Whilst the line has been closed, we’ve installed a track loop at this station. This allows trains to pass each other on the line and allows us to deliver more frequent services. We’ll soon start work on building a new station platform, which accommodates the new loop, as well as a new accessible bridge, with stairs and lifts to connect each platform. Due to the extensive drainage works required to prevent flooding at the station, and delays in obtaining the required land agreements to undertake this work, we will need to continue work at the site throughout 2024, with a reopening date for the station planned for late 2024.
We advise customers to use Treherbert or Treorchy station until we can reopen the station for passengers and we will be running a shuttle bus Northbound to Treherbert and Southbound to Treorchy which will integrate with the train timetable.
Bus replacement information
We will continue to carry out essential electrification works on the line and as a result trains will be replaced during the evenings from Sundays to Thursdays, so we’re asking our passengers to check before travelling.
Our journey checker tool will be updated with the replacement bus information.

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:
