GWR Collett Hall class 4-6-0 no. 5998 Trevor Hall.
There's still some doubt concerning the location of this shot and Roger Winnen suggests: "This could be taken at Rosvidney located about a ½ mile further west of Arch Lane. There is a road over the line at Rosvidney, however with no bridge in sight this photo may have been taken from the field where until recently a cow and a donkey had their home for many years. The bridge could be just out of view."
