Sorry fellas but you are not talking about any signal at Sunbury that I
know of......
Down trains departing Sunbury face a two pos col lite sig. protecting the
points of the access crossover for the centre siding,
which also has another crossover to access the up platform.
The Signalman withdraws two Annett keys from the frame [which locks all
home signals at danger that would allow a conflicting move] and shows them
to the Driver, He uses these keys to operate both crossovers and the Driver
on sighting the Key is authorised to pull past the Red 2 pos. Home towards
the Semaphore departure signal[2 pos of course] untill clear of the points.
Under signalmans instructions, he will set back into the centre siding, or
if he is the next up to depart through the 2nd crossover into the up plat.
He can then run around via the centre siding to the front of the train.
Down trains arriving Sunbury pass a distant, a home at the level crossing,
a home at the bluestone bridge, and departure home towards Rupertswood.
Departing Sunbury on the Up a 2pos col lite at the crossing and a 2 pos
semaphore near the down distant. So the only Yellow indications you will
see will be from the two distant signals.
Hope this helps Rod.
