Geograph - photograph every grid square

I didn't count them, but I reckon there are six or seven of these short walls on the Edinburgh Road in Bathgate leading towards the town centre from the Guildiehaugh (or Tesco as it is now more usually called) Roundabout. They all have an identical form, though probably vary in length a bit from section to section - the walls are just over five feet high and are always flanked by posts with ball finials which go a couple of feet higher.
Hopefully one day there will be a wall website to clear up these mysteries but at present, sadly, us wall-spotters have nowhere to go! Usually, walls like this mark the boundary of an old estate or something similar, but that seems highly unlikely in this case. The ground behind the wall descends steeply to the railway line. I mention this because of the gaps between the wall sections - not one of the gaps, as is often the case, could possibly have been there to provide access to anywhere. Furthermore, even if the ground was flat, the gaps are so regular that even then there could never have been a need for so many points of access.
Each wall section is joined by a slightly concave stretch of metal railings. They could be there because the wall fell down, but then again, if that was the case, would it not have been cheaper just to replace the wall as opposed to erecting fancy posts at each end of the surviving walls?
Back then though, sometimes price wasn't a problem - life was tougher, but people expected things to look nicer, if it came from their taxes. In contrast the recent electrification of the railway lines has led to hundreds of ugly identikit concrete bridges everywhere round here, an architectural disaster in my book.
The wall is still a mystery though - before the railway came it was mainly farmland round here.
