Guided metal rods joined lengthwise in runs of up to several hundred metres, as used by NSWGR to transfer the action of a remote lever to the switch rails of a point (turnout).
Multiple rods headed in the same direction were commonly clustered laterally through common guide locations. Adjacent rod guides interlocked together. In this case there are 3 rods in the run.
Use cranks <kuid:368725:20089>, <kuid:368725:20090>, <kuid:368725:20267> and <kuid:368725:20268> to branch 1 or 2 rods from the rodding run.
