Single light colour light signals with staggered marker light
Single light colour light signals with a staggered marker light are:
- automatic signals, or
- distant signals.
Automatic signals
Automatic single light colour light signals have a red marker light.
The marker light is lit if:
- the signal is at STOP, or
- the main light fails.
Distant signals
Single light colour light distant signals have a yellow marker light that is lit if the main light fails.
Some distant signals indicate STOP if the line between the distant signal and the next signal is occupied.
Distant signals may have a signal identification sign with the same signal identification as the signal ahead. The identification sign includes the word DISTANT.
