Cogan railway station is located on the Vale of Glamorgan Line and provides services to Barry, Rhoose, Bridgend and Cardiff. 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. Most of the station buildings still stand and have been used by several private businesses including a shooting range, a garden centre, a second hand car lot and a marine chandlers. The area originally covered by the Cogan and Penarth Dock's railway sidings and engine maintenance sheds now contains a large Tesco supermarket.
