Signal aspects

[NW Modeling List]

"For instance, if G did not have a number plate, it would be a Stop signal 
instead of a restricting."

Ben,
     Your diagrams got deleted, so, I'm guessing on which aspect you are 
speaking of and throwing this into the mix to confuse things even more so 
pay close attention.
     If an intermediate signal, displaying a "Restricting" aspect, has its 
number plate blown off by the wind, that doesn't automatically just change 
the definition of the aspect from "Restricting" to "Stop". When the wind 
blows the number plate off, the signal then becomes "imperfectly" displayed 
per rule #27 and that includes several exceptions.
     If the signal just happens to be "blacked out", that does not make the 
intermediate signal a "Stop" signal. The reason being is that the most 
restrictive aspect that could have been displayed before the wind blew the 
number plate away, was "Restricting".

diagrams are still at the following url:
