CPL signal aspects

[NW Mailing List]

You're correct Eric, it is not on  the original  N&W,  but
inherited from the NKP. At Euclid, Ohio,  there are three
consecutive color  light signals that display flashing green
and flashing  yellow.  Timetable instructions indicate that
"signals 1804-1788-and 1774 will display flashing  green
for clear and flashing yellow for Approach.   Rules 281 and
285, Book of Rules, modified  accordingly."  The instructions
don't tell you why they flash.  It's so  that engine crews
don't confuse N&W signals with those of the  paralleling
Cleveland Rapid Transit.
 
Same with Rule 283-B, the Operating Rules don't tell  you
the theory.   N&W's Henry Nase, Manager  of Operating
Rules,  noted that the Diverging Approach  Diverging takes
over what the Diverging Approach leaves out in some  cases.
A Diverging Approach means the train will proceed  through
turnout or turnouts at prescribed  speed,  but will be ready
to stop at the next signal.  But suppose the 2nd  signal has
been cleared for a diverging movement also ? The  Diverging
Approach Diverging aspect lets the engine crew know  that
they won't have to stop at the 2nd signal.   EXAMPLE: 
routing an eastbound around a train stopped for a  pusher
at Farm, then resuming the eastward main track at  Tug.
