of Barry Docks, near Cardiff.
Barry Railway Company was promoted by interests in coal mining and steel in the South Wales valleys as an alternative to the existing rail service to Cardiff docks in Tiger Bay. It's primary interests were always very much in transporting the commodities of its sponsors.
The company persuaded P. and A. Campbell to run steamers from a pier built alongside the dock across the Bristol Channel, but later put their own fleet on the station. Although the "Red Funnel" fleet as it became known gained a great measure of popularity, the company was dogged by legal disputes with its main competitors, P. and A. Campbell, legislation restricting their freedom to develop services and the legacy of the high cost of its three magnificent new steamers
Starting in 1885, the company constructed 7 miles of track from Cardiff, and the construction of railways of about 26 miles in length from the docks to the Rhondda Valley. Additionally, access was created to junctions with the existing and authorised railways to all the other great mineral-producing districts of South Wales.
