Signal aspects

[NW Modeling List]

Ted,
   Here's a diagram of what the aspects are, both in position signal and 
CPL signal diagrams.  Now, the aspects were changed around 1952 and this 
change eliminated the horizontal aspects on the B arm of the signals, and 
the marker lights underneath a B or C arm if the signal was so equipped 
were also eliminated.  This marker was replaced by a letter plate "S". 
This is something Uncle EdK explained to me a great many years ago.

   Now, the aspects as I have them named:  They weren't known by a "name" 
so to speak in the Position Signal era as far as I know, but now the color 
aspects are named as I have them listed.  The indications are quite 
lengthy, so I left them out.  I hope this helps.

   Oh, and the number plates were removed in the 60's or 70's.  These 
signals now have names as per the Southern practice.
