Thanks for all the signal discussion!

[NW Mailing List]

signals are quite fascinating.
I have a yard throat for my layout on a module and I have just gotten it 
all working with
single target signals using bi-color LED's hooked thru the digitrax 
system and the JMRI software.
Works like a charm but you do need some mad skillz because you have to 
do programming at a certain level, not deep computer programming, but 
some practical logic thinking is in order.
In deciding a signal aspect you have to look the possible circumstance, 
switch position, occupancy, the probably speed you want the train to 
run, and study the rule book how the railroad did things.
All the talk is invaluable to me, I understand signaling, its all the 
various circumstances that
cause the signal aspect that become of interest and it can be differrent 
from signal to signal.
Sure there are the basics, but then you get sidings, crossovers, 2 
railroads crossing each other
etc it gets interesting. The you have differrent railroads using 
different signal designs, its like a different language.
