A catenary spline including stanchions on the right-hand side of the track in the direction in which the spline is layed. Instead of a concrete base, the bottom of a stanchion is supported by a horizontal steel member that projects to the side of a bridge girder beneath track level.
The model spacing between staunchions is 50m. For the spline meshes to be represented in game with the correct proportions, a spline point should be added at an approximate multiple of 50m from the prior point.
Suitable for straight track and for curvatures with a radius exceeding 450m. For sharper curves use <kuid:368725:30121>. 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 wire is centred over the track when the stanchion is 3.75m from the track centre.
The model meshes are based on those in a workbook provided by David Owen (davido). Thanks to David for sharing his work.
