The Barry Railway line between Barry and Trehafod had opened for goods trains on 18 July 1889, but initially there was no passenger service.
A passenger service over the route, which ran through to Porth, was inaugurated on 16 March 1896, and Efail Isaf was one of the stations opened that day.

The line and station closed to passengers on 10 September 1962.

The layout was of four lines, two through lines and two platforms on the outer lines only; a short siding existed additionally.
The platforms remain and a public footpath now runs between them, the platforms mainly intact and the foundations of the buildings still evident with original floor tiles showing in places.
