There are still plans I believe to expand TrawsCymru. According to the review published by Dr Winckler in August 2013, three proposed services are to join the network sometime in the future..
"If it is accepted that TrawsCymru is a network of medium- to long-distance, strategically important bus services then it is likely that new corridors will need to be added. The 2013 TrawsCymru draft business plan proposed that three new routes for 2015/16 2017/18, as follows:
- Service T6 (X50/X52): Wrexham, Ruthin, Denbigh and Rhyl;
- Service T7 (280/281-80-X43/43): Carmarthen, Llandovery, Brecon and Abergavenny; and
- Service T8 (X71/71): Newtown, Welshpool, Oswestry and Wrexham.
It also identified the potential for a Cardiff Cardiff (Wales) Airport service, which is now
operational as T9, and a Deeside service."
