LSWR M7 0-4-4T No 54 with a train somewhere on the Meon Valley line in around 1947.
I suspect it was taken from the side of a track leading up to a bridge over the railway between Tisted and Privett stations. If so the grid reference is SU684199. If it is then it’s the main A32 road glimpsed to the left of the bank of trees on the east side of the line.
It is the same locomotive as 30054 1950s Farringdon Halt and also quite possibly the same pull-push set. It received BR lined black livery in April 1950, thus this 1947 date could well be correct. But also could be 1948/49.
