Is this Ackholt Farm?

This picture was in Dover library labelled market gardening ,Nonington- I took a copy because t was all I could find on market gardening. I'm now convinced this is grandad, dad and his brothers, maybe grandmother maybe an aunt.
Perhaps only one other farm that fits the bill. Land very flat, there seems to be some kind of sheeting over the farmhouse rendering it unrecognisable? Perhaps it doesn't matter if it's them or not- just that I think it is.

New thought- Is that a train passing by the cottages? if it is that narrows it down, that's the train going to snowdon mine and Ackholt farm is the only Nonington farm that backs on to the rail road.
