Opened in 1983, Cathays is (I believe) the newest station on the old Taff Vale Railway (opened in 1983) and the only station opened on the line since the demise of the coal mines that the TVR was built to service.
On the right of this shot is the hut holding the new ticket barriers that Arriva Train Wales installed. When the station is manned, the passageway beside the hut is gated closed, and passengers must pass through the hut to enter and exit the southward-side platform (aka the down platform).
Immediately to the north of here, on the east side of this surviving track, used to stand a large rail yard, complete with several impressive railway sheds. I don’t know when the yard’s track was ripped up, but the sheds were only demolished a few years ago.
