I do agree they have to account for truck turnaround, and it looks like they went with option B in the attached for 10m trucks and refuse collectors. But I think years ago in the planning stage they should have been able to position things to allow for a treeline screen here.
I'm not as bothered by the two-second view from the coaster but this fence appears very visible from the walkway and bridge photo-spot once you enter the land, and it feels backyard-ish to me. I think in this case, given the extensive scope of scenic elements in this land, a 4-meter high rock face/feature at this location and maybe even a rock arch over the track landing in the grass would have been called for.
I understand "there's only so much money" but about 30 meters down the track is an elaborate rockwork section and two arches that look only visible from the coaster. One could have been located at the wood fence area so it's enjoyable from the coaster and improves the first-impression walkway view and land ambiance/immersion.
