 Two more viaducts existed at the north end of Edwardsville which were demolished shortly after the Beeching cuts of the 1960s.The main reason for their demolition was subsidence and the viaducts had been strengthened with huge wooden supports for a number of years.Until June 1964 (when the adjacent Vale of Neath Railway "High Level" station was closed, along with the Pontypool Road to Neath line that passed through it), this was a large, two-level junction with services to numerous locations and a hub through which large amounts of coal were transported.
