The signalls are all two colour ie. Red or Green. Most have a trigangle
with an A in it under them. This means that it is an automatic signall,
these are green (ie no trains in area). Those with an 'A' are red (ie
no trains in area) they protect Points and used to protect the swinging
gates but these are auto booms now. I think that the green means "Clear
for one section" red "Stop". At the exit and entry to the line it is
normal 3 position auto signalls showing only medium speed not full.
(expect the signall at the end of newmarket station which shows full
speed for trains going to Essendon.
I also now have one more question:
In Melbourne signalls that are auto have the lights offset Home signalls
have the lights in a vertical line. All the signalls in the city loop
are in a vertical line. Does this mean that they are all home signalls
and can't be passed at "Stop"? If so how does the signall man give
permission to pass them at stop if there is no way of showing "red over
red over yellow"?
Thanks,
Chris
