Electrification of the Treherbert railway line

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.

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:
