@ArrivaTW why have you sent a single carriage out on the busiest cardiff - swansea journey of the day? Awful customer service More @ArrivaTW your services are appalling and few fault trains. Obviously this what happen when you have old trains - simply terrible. Another miserable, cramped and sweaty train journey courtesy of @ArrivaTW. 5.22pm MCR to CHR. It's just shocking that the problem of overcrowding doesn't seem to be getting addressed. It's simply getting worse! @ArrivaTW Please invest on the North Wales train line! @networkrail - 2 coaches, Holyhead to Shrewsbury train packed! And only 2 on the 5pm train home. Standing at central. Families left stranded at Queen street. Diabolical service. £91 month #absolutejoke @ArrivaTW overcrowded, overpriced, understaffed, dirty, uncomfortable, late. That's your trains in a nutshell
