The headcode is for a service between Bournemouth and Weymouth, and I am now certain that the train is at Wool, on the down line, with the photo taken from alongside Dorchester road. Location of the crossing, signal box, and the distinctive bracket starter signal all confirm this. 76017 was allocated to Eastleigh from construction until March 1960, when it was transferred to Salisbury, so I would date the photo to the late 1950s. Coach set 228 has two container wagons attached on the rear.
