signaling (was signal brackets)

[NW Mailing List]

Mike, et al.,
Thanks for your attachments.  Several years back, I went through a
series of posts to try to explain to myself and others how N&W signaling
was done.  I will try to present some of that information again and if you
will ask specific questions, I will provide the best answers I can and
hopefully others will join in the conversations.
First you have the block occupancy signals also called intermediate I
believer because they are intermediate to control points.
These signals have a single arem and can display only three aspects:

CLEAR: both the block you are entering and the subsequent block are
unoccupied.
Indication: Proceed at prescribed speed

APPROACH:  the block you are entering is unoccupied, but the subsequent
block is occupied
Indication:  Proceed at no greater than medium speed, preparing to stop at
next signal

STOP AND PROCEED:  the block you are entering is occupied.
Indication:  Bring your train to a complete stop and then proceed at no
greater than restricting speed being prepared to stop short of any other
train or obstruction.

I think these are the easiest to understand and I have included some photos
of this type of signal.
Let me know  your questions/comments etc.
