"I also noticed an old Morris 8 like my dad used to have."
Do you mean the only car that's parked facing up the slope? I think it's a Series E, circa 1938/39. Had one once. Built like a brick outhouse and just as quick (55 flat out downhill with wind behind it). Rusted like a bucket.
That's the one. I stand corrected on the model (hangs head in shame!) But, just behind a small tree is a light-coloured car - possibly a Ford Anglia/Prefect? Also spotted in the car park, a Morris Minor of reasonable vintage (pre Minor 1000 which had the larger back window).
So I'm beginning to think mid 50's.
Trying to sharpen the image a bit and look in greater detail for things connected with the railway signal... The track seems to come right round the nearest edge of the bay. And the radius of the curves round the bends looks far too tight for a main-line track. And is it on concrete? The signal and box seem to be out of proportion to the apparent railway.
But now, I have to undertake various domestic duties (groan), so I shall have to ease out for a while and let wiser and more experienced heads that mine provide and answer.
