A mechanically-driven rotating disc indicator to inform whether a trap point is open or closed.
Designed for use in conjunction with (a) 'Protrack NSWGR' series with<kuid2:368725:49000:2> 'Protrack NSWGR Mesh Library', (b) an invisible mojunction asset such as <kuid2:44090:1007:1> Invisible Lever, (c) 'NSWGR Protrack rusty rail only, for LH/RH catch or trap point' <kuid2:368725:20061:1> <kuid2:368725:20060:1> and (d) 'point rodding,...,NSWGR' series starting with <kuid:368725:30062>.
The indicator crank is driven by connection to a rod running parallel to the track. This rod also operates the crank adjacent to the trap point. The rod PUSHes on the cranks of the trap and its indicator.
Note that this asset cannot by itself switch the direction of a junction. An invisible switch lever must be added to the junction. An association between the invisible lever and the trap-point indicator is established through a naming convention. If the invisible lever is named 'HR_16', then the indicator must be named the same way with the suffix '_i' appended: 'HR_16_i'.
