Funicular Railway Signals
Wayside signals, as seen on the Funicolare Montesanto and Funicolare Centrale in Naples, Italy.
Why does a funicular railway need signals when it consists of two cars connected by a cable? The signals display red/green aspects based on whether the doors of the cars are open/closed. I'm not certain why this is necessary, as I would imagine there is some failsafe to prevent the system from starting when the doors of one car are still open.
Red-red: both cars' doors are open.
