 Until 1968 Cogan had two further platforms across the other side of the main Windsor Road and located on the Penarth and Sully branch line, from the Cogan Junction points down the coastline to where it rejoined the main line at Cadoxton.The through link was closed under the effects of the Beeching Axe and the rail spur now terminates at Penarth.Dingle Road Halt and Penarth station remain open but the platforms at Cogan were closed when the line was reduced to a single track branchline.
