[PRR-talk] Markers and classification lights

John,

Note the date of the rule book you are quoting.? The PRR discontinued the use of class lights circa 1939.? So you need to consult a pre-1939 rule book for the answer to your question.

Can it be true that a section, running at night and not clear of main track, 
could display no red 
lights at all to the rear?  This appears to disagree with all the references I 
can find.  (In 
Josserand's Rights of Trains there is an interesting example of a train running 
against the 
current of traffic where there are three or more main tracks, in which case 
yellow markers are 
displayed to rear, but even then a red light must be displayed "on the platform 
or the cupola" -
- with two main tracks one marker is red, and the one next to the other main 
track is yellow, 
when running against the current of traffic. Did PRR follow these practices?)  
When trains 
were clear of main track, yellow was often displayed to the rear; PC C.T. 400, 
1968, states in 
Rule 19, "On main tracks where no form of block system is in use, yellow 
displayed to the 
rear when train is clear of main track."
