Parish records showed the first use of the name Treherbert from January 1855, commemorating the Herbert earls of Pembroke, one of the ancestors of the Marquess of Bute. The first 38 wagons of steam coal were transported from the newly extended Taff Vale Railway station at Gelligaled (Ystrad) to Cardiff Docks on 21 December 1855. Installation of the railway line facilitated the rapid expansion of the village, and the need to build new houses, the first rows of which were built at Bute Street, Dumfries Street, and Baglan Street.
