Signals for dummies

The signal in the attached image is at CV459.7, Spring, Va. The east end of the siding starts at Tacoma (CV458.3). The taller signal on the left is for the mainline and the lower set on the right is for the siding to re enter the main as trains move WB. At Spring, there is a coal loadout which has changed hand numerous times and is painted orange.  The lower two diagonal targets are for the notification of the spur into the loadout. Signal indications could include Clear (Rule 281 - High Green), Adv. Approach (Rule 282A - Diag. Yellow over Diag. Yellow), Diverging Approach Diverging (Rule 283B - Red over Flashing Diagonal Yellow) Diverging Approach (Rule 286 - Red over Solid Diagonal Yellow).

If the lower diagonal signals are not present, as is the case for the EB signal at Tacoma, this all changes.

A signal like the one in the attached photo is/was positioned at the end of
the siding at Tacoma, VA (visible as you are leaving the siding and going
back onto the single track main).  I'm interested in understanding how it
would be used and what the signal at that location coming from the other
direction would look like and how it is used.

I'd also be interested in any documentation explaining (again for dummies)
the various aspects and the rules associated with them.
