From 16 April 2018, Welsh Government are making changes to the TrawsCymru service between Carmarthen, Swansea and Cardiff.
Existing service T1c will become a limited stop coach service between Aberystwyth and Cardiff, and will be increased to also run on Sundays and Bank Holidays.
A separate service, T1s, will run on Mondays to Saturdays between Carmarthen and Swansea, offering connections at Carmarthen with services T1 from Lampeter and Pencader and T1c from Aberystwyth, Aberaeron and Llandysul.
Service T1s will also offer a service from Swansea to and from the National Botanic Gardens. Information will be available at www.trawscymru.info
