The new section of track is almost complete; the cant (superelevation) on some of the curves needs increasing, and when we have a few consecutive days of good weather, the track needs ballasting. Most of the curves are of 7' radius, a few lengths are 5', and there is a short length of 4' radius. The picture below shows why the reverse curves are needed. To the right of the trackbed in the foreground is a path, to the right of which is a 5ft high earth "hump" between two trees, then the pond. The trackbed (and path) then has to get round the step in the fence, and be in the correct place at each end of the garden seat to allow the seat to stay parallel with the fence, before the track curves right again to avoid the vegetable bed and arrive at the lawn.
