Travelled on this service today only from Cardiff to Newport though
12.30 out was ex
TPE▸ 158769 (2 cars), return journey was the 12.22 from PMH arriving at Newport at 15.34. It was 2 x ex TRE 158's - cant remember the numbers now but 776 and 778 I think, but I was quite disappointed I still havent managed to get on a refurbished 158.
Myself and 2 passengers had a carriage to ourselves on the way back from Newport, and one of the other carriages looked to be empty too, most passengers seemed to be on the front 2 carriages so perhaps this extra train was only added later into the journey?? You could say this service was the opposite of overcrowded for once (although it was the tail end of the journey, many people would have got off in
BTM▸ )! Mind you, this would have been the 16.30 back to PMH so I think a 4 car is needed for that particular train.
