Re: Signalling in Victoria

[Steve & Sheena Dalton <daltongang@smart.net.au>]

I have not found any one yet mention how you read signal's in Victoria.
For those who don't know,  Signals are read  TOP TO BOTTOM LEFT TO RIGHT
meaning the top signal is to the left and so on.
In two position signal the lever numbers are different to the signal
post numbers, and in three position, the lever number corresponds with
the signal post number and when a signal shows something like 34U this
means the lever 34 is for both signals and depending on which way the
points are laying is to what signal goes to proceed.

As for some of these signal aspects listed below, how about the
following,

It should be noted that the driver must stay at medium speed until the
next fixed signal unless special instructions have issued.
