Signals

[NW Mailing List]

Agree that a series would be great. Rules and signals changed, so an 
article for each period when a given standard was in use would be 
perfect.

Jim,
You took the words right out of my mouth! I am trying to get the 
signaling
system on my railroad ready to install. However all the rules and such 
have got
me just plain confused! An article laying it all out for the late
steam era would be a huge help!!!!!

Jimmy is correct. PRR signal aspects are similar in appearance to some
N&W aspects, but that is where the similarity ends. The N&W had
different rules for their aspects and how they apply.
Older N&W rules had two horizontal yellows over a single marker. That
was replaced later with a single horizontal over a marker light with the
letter "S" attached to the interlocking number board on the signal.  
That
is just one example of MANY differences.
It gets complicated, and it would take a great deal of time to explain 
some
of the signal subjects that have been brought up lately. That's why I 
haven't
chimed in on them.
Maybe I should write a book...
