I`m not sure if i read this right ,but you still prefer the 'open' crossing look as in Dave`s picture. And to be honest so do i,as the crossing gates and fencing tend to 'hem' the railway in too much
Looks like a bit of a Catch 22 to me.
The fence does 'hem the railway in', but to my eye it does in the prototype photo too. Maybe as noted the perception would change with the fence painted dark colours.
The 'open look'
sans fencing & gates does look nicer, but the rear gates help disguise the road-to-backscene join, & assists the illusion of the road dropping to the town. So do you keep the gates & have an easier job of meeting the backscene, or remove the gates & devise a more intricate (read "difficult") way of joining the two. By the way, I think the backscene itself looks great & fits well.
To justify the 'open' unfenced look you could always take prototype inspiration from the nearby Sling Branch, from Milkwall on the Coleford line. This was originally a Tramway route, and was left unfenced even when converted to standard gauge, with at least one open crossing, albeit over a little-used lane. See various Forest of Dean and Ben Ashworth books for details.
Edit: I have to keep reminding myself this is NOT a Forest of Dean-based layout
the Soudley Crossing inspiration is confusing me!!
But I bet the'old Tramway' storyline could be applied to some of the Welsh lines..?
