Grand Union is proposing to launch its new service between Carmarthen and London as soon as it is able to secure the necessary rolling stock. The planned start of 2025 is not currently achievable with the long lead times on new build trains, and Grand Union is exploring various options to deliver this important service as soon possible.
A new parkway station is proposed to be built at Parc Felindre close to Junction 46 of the M4 motorway, but initial services will call at Gowerton and bypass Swansea thereby reducing journey times from further west to Cardiff and London by around 20 minutes. This new service will bring more journey opportunities, wider economic benefits and significant employment to the people of South Wales.
The formal application to the Office of Rail and Road was submitted on 21 June 2022 following a period of industry consultation.
