NW-Mailing-List Digest, Vol 80, Issue 13

[NW Mailing List]

some multi head signals might not have the full coverage of indicator 
lights as the locale may never indicate the potential full signaling 
possibilities, call it a matter of economics or economy of signals, use 
only what you need.
Say a turnout is leading into a terminal stub end, you might not have 
any green signal indications, so you won't have any on the signal.
Some signals may have one head, but with a secondary single light below 
it, could be white, amber, or blue or purple, which can indicate a 
permissive signal on red, the train can cross the red at restrictive 
speed perhaps after a full stop first.
Checking a rule book is key with all the signal aspects.
Theres a general standard between all railroads but yet each railroad 
has its own "tweaks" to the rules.
