This New York Central rulebook is an interesting study in early signaling, much like that of the Western Maryland rulebook from 1913.

For instance, you won't see the green over green aspect today, EXCEPT for maybe some dwarf installations on former NYC trackage (that's according to the 1988 reference card for Conrail indications).  This is because today, the generally accepted practice is to assign the top head to high speed routes and the middle head to medium speed routes, and you can't assign a clear to both at the same time.

Note rule 281 is called PROCEED instead of CLEAR as is the practice today.

Another thing not noticed until you examine the actual rulebook pages is that the signal indications don't have a NAME, as is customary today, they just have a description.

In looking at the rulebook pages, you will also note the following things:

The use of PURPLE as an alternative to red in:
     Rules 287 and  288 - In the bottom position of the 2 aspect dwarf color light dwarf signal.
     Rule 290 - In the upper position of the 2 aspect dwarf color light signal.
     Rule 292 - Stop in all three dwarf signals: semaphore and 1 and 2 aspect color light.
     Rule 293 - Siding derail target, in derail position. 

Note the use of BLUE in Rule 299A for raising the water scoops.

Sorry, couldn't fit everything on the single page reference.

Their is also no use or reference to doll posts / arms.
