Re: Signalling in Victoria

The term "caution" is used in 2 pos territory and the term "warning" is used in
3 pos territory. The terms are not interchangeable.

The reason the term "caution"  is used in 2 pos. territory goes way back to
when distant signals showed a red light when the arm was horizontal, (caution
position) back then, a driver upon seeing a distant at caution could expect the
track to be occupied between the distant and the home. Hence the term "caution"
The term "warning" implies that you are being warned in advance about something
and is used in 3 pos territory to warn about an upcoming restrictive signal,
caution means to travel cautiously as in, the track may be occupied.

They changed the lights (and the meaning of a distant at caution) in distant
signals to yellow at the same time they introduced auto staff exchangers.
