Re: Signalling in Victoria

Calling David Langely,

David, Could you dig up and post the circular that introduced 3 pos signalling?
(my copy is still in Australia)

It would be helpful to quote the bits where it specifically states that top
arms are for mainline moves, bottom arms are for diverging routes, low speed
for yard moves. (I can't recall the exact wording)

Eddie, this is not a "maybe" situation. As introduced the arms indicated
mainline, diverging etc. Just like the system they copied. BTW, the US still
uses 3 pos in its original form, only VR would take a perfectly good route
signalling system and try to bastardise it into a speed signalling type system.

I think SAR kept with the route system and didn't change the meaning of the
arms/lights.

Mark.
