Catenary stanchion and wire supports in use by NSWGR in the mid 20th century to serve a single track on the Sydney suburban, Central Coast and Blue Mountains lines.
The height of the pickup wire above the railtop is 5.3m, midway within the NSW operating range of 4.75 to 5.8m. The cantilevered stanchion is 3.75m from the track centre and on the left-hand side of the track in the direction in which the track was layed. The cantilever enables wire support from the left in cases where there is no space for a stanchion to the left of the track.
The model meshes are based on those in a workbook provided by David Owen (davido). Thanks to David for sharing his work.
