The GWR line can be seen at the higher level and diverges here heading under the bridge screened by the vans of the train. Wilton LSWR station is beyond the bridge to the left.

The gentleman seen to the left of the train was David's good friend the late John Batten; the pair had met that day at Salisbury station for a visit to the S&DJR and had walked lineside from there to Wilton photographing the scene. In those days this was quite normal practice and did not attract adverse attention from BR employees.
John and David had met whilst independently photographing trains at Shap in 1960.
