There’s some good news today (29th May 2016). Today is a Sunday, and for the first time in many years Cardigan will be served by a mainline bus service (in recent years, the only Sunday buses in Cardigan have been the coastal path walkers’ buses, which only run on Sundays in the summer). However, there still won’t be any bus services in Cardigan on Sundays during the winter, since today’s new Sunday services are only operating from the last Sunday in May to the last in September. The new Sunday timetable will also run on bank-holiday Mondays, again until September.
So, what is Cardigan’s new summer Sunday service like? The answer is that there are three journeys to Haverfordwest and back, three to Aberystwyth and back and two shorter workings, one to/from Newport and the other to/from Fishguard. Two trips in each direction appear to be through services between Aberystwyth and Haverfordwest (whether or not they actually require a change of bus in Cardigan, as I believe is often the case with the Mon-Sat T5, I’m not sure).
As you would probably expect, these services are advertised under the TrawsCymru T5 banner, but unlike the rest of the week the Sunday T5 appears to operate a fixed route, with all the Aberystwyth workings travelling via both New Quay and Aberporth. Really then, north of Cardigan this is the old TrawsCambria 550 in disguise. Confusingly, with the services to Haverfordwest the timetable doesn’t indicate whether Trecwn and Mathry Road are served.
