Workmen's trains were provided, along with specials for visitors and dignitaries, but the railway never provided a public passenger service. The quarrymen's carriages were unsprung and open to the elements, having neither roofs nor doors. In the frequent event of rain and cold passengers usually covered themselves with sacks to keep out the worst. Each carriage could carry 24 quarrymen "at a pinch". The carriages resembled enlarged versions of many used on garden railways in fine weather. 16 of these were built in two batches between 1878 and 1908, each bore a single letter in the series A to P. The service was withdrawn on 9 February 1951, rendering the carriages redundant. Seven survived, six were given or sold to the Talyllyn Railway where they were modified or cannibalised to such an extent that no Penrhyn bodies survive there. The seventh survivor was acquired by the Penrhyn Castle Railway Museum, where it remained on view in 2016. Contradicting this to a degree is the Moseley Railway Trust which has carriage "O", which came into their hands after a long tour of various preservation sites, starting with Bressingham Steam and Gardens. The trust has also built a replica of carriage "H".
