I found it online as Aldershot Town, which it equally isn't, nor is it on the Camberley line!
However, the fresh chalk-face in the background rang a bell and made me wonder if it was the Meon Valley line through the Hampshire chalk which only opened around 1900, and had very spacious layouts.
After a bit of digging I think it is Droxford:

the 1910 map shows the footbridge and signalbox as in your photo; the loading gauge and a windpump (though not a water tank) show in the pre-closure photo.
The footbridge seems to have been standard along the line - West Meon and Wickham definitely had the same design.
PS here is a correctly labelled photo showing the box and footbridge from the other side:
