The Switch Indicator
The rare Red and Green switch indicator at Motibagh, Nagpur (Narrow Gauge).
There are two different types of these indicators.
One is the point/switch indicator which has a white disc and a white light showing through (when point is set for straight movement) and a green light without disc showing through for movement over the diversion (most common).
In case of a Trap Indicator, a red light and a red disc by day are shown when the trap is open and a green light is shown when the trap is closed.
Diesel Shed Motibagh can be seen in the backdrop.
