A catenary wire spline for sharply-curving track.
To maintain contact on sharp curves between pantographs and the pickup wire, a spline point should be added every 25m.
Suitable for track with a curvature radius between 200 and 450m. For gentler curves use <kuid:368725:30132>. The default height of the pickup wire above the railtop is 5.3m, midway within the NSW operating range of 4.75 to 5.8m.
The model meshes are based on those in a workbook provided by David Owen (davido). Thanks to David for sharing his work.
