N&W signal route diagrams

[NW Mailing List]

I was asking my self the question about the dark bottom on the signal 
with the red.

It would be a stop indication no matter what, since we are at an 
interlocking (passing siding)
I was interpreting how the green and reds are working.

For an all clear the green only was lit on top, for a stop if the 
turnout was not thrown theoretically you could have Red/dark. But since 
you may want to indicate you have a turnout present, that may be the 
purpose of the signal, so you need red/red.
For the circumstance a train in the main track of the siding, turnout 
not thrown, train behind gets the red/red. Lets say the train ahead is 
not moving, the 2nd train stops, the dispatcher throws the turnout and 
lets the 2nd train pass, it gets the red/yellow.
