Yn ddiweddar, gwnaethom gyflwyno tocynnau bws / rheilffordd cyfunol ar wasanaeth bws Traws Cymru T1, sy'n cysylltu Aberystwyth a Chaerfyrddin, ac sy'n profi'n boblogaidd gyda theithwyr. Mae camau'n cael eu cymryd i ymestyn hyn i rannau eraill o'r rhwydwaith. Mae Gwasanaethau T1 Traws Cymru (Aberystwyth i Gaerfyrddin), hefyd wedi derbyn buddsoddiad i newid yr wyth cerbyd a'r cyfleusterau depo i weithredu ar drydan batri.
We recently introduced combined bus / rail ticketing on the Traws Cymru bus service T1 linking Aberystwyth and Carmarthen, which is proving popular with passengers. Steps are being taken to extend this to other parts of the network. The Traws Cymru T1 Services (Aberystwyth to Carmarthen) has also received investment to convert the eight vehicles and depot facilities to battery electric operation.
