By 1890 preliminary borings for the Universal Colliery had proved successful, and, in the words of a “Cardiff Times” reporter, “this picturesque little valley is likely to be converted before long from its present peaceable and tranquil condition to be the source of great wealth”. Priority was the construction of a railway line to the site of the intended colliery from the Aber Junction in order to convey the heavy equipment necessary for the sinking. In June 1890 the Rhymney Railway Bill, the object of which was to make a new branch line in the Aber Valley, was grouped to come before a Select Committee of the House of Commons. It was sanctioned in July 1890. The Railway Company engaged Mr T.T. Davies, head of a Cardiff engineering firm, as Technical Director of the construction and the first sod was cut at the Aber Junction end on 23 January 1891. A small number of craftsmen were employed, supported by a few hundred navvies paid 4½d to 5d an hour. The works engine used in the construction was appropriately named “Aber” and was driven by Alfred Dawes of Abertridwr. Throughout 1891 and 1892 as there was no infrastructure in small hamlet to house railway workers they were billeted in Abertridwr in adapted old buildings bearing the names of “Yorkshire Hall”, “Somerset House” and “Dudley Cottage”. Consequently no “foreigners” disturbed the comparative tranquillity of the hamlet. As the construction of the railway line became ever nearer completion towards the latter part of 1892 so the land around the site of the proposed colliery was cleared and engine sheds, a goods shed, a railway station and some craft buildings were erected. Fifty five men were engaged to work on the eleven engines in the Sheds. On 1 February 1894 the Railway Station was opened for passengers for four journeys a day to Caerphilly(3d) with connection to Cardiff(9d). Return fare to Abertridwr (cost 1.1/2d). First train driver was Mr Fred Butt. But what marked this historic occasion was that, at last the village acquired its own name as opposed to being included in the general term of “Aber”. During the times of the Universal Colliery Disasters of 1901and again in 1913 the railways were used as a means to repatriate many of the bodies of those miners killed back to their homes within Wales and the borders. The site was cleared and is now Plas Cwm Parc housing site and the old railway track has become a cycle-track.
