Here is the list of signals as given by the CSX rules (1987)

Rules C-280 through C-297 apply exclusively on the former Chessie System

\ /
-O-  means flashing light
/ \

[ ] is a signal target not lit(not used in that signal indication)

[1]
[2]
[3] or [123] is a numberplate on the signal.

X is used to denote gray in the book...used for distant signals
x is used for white in the book, used for APP signals
o is a white lunar light (used on B&O color position signals)
O is a yellow lunar light (used on B&O color position signals)
() used for round B&O color position signals
-|\ is a yellow triangle on B&O color position signals

Except as indicated in Rules C-281(f), C-281-B(b), C-281-C(b), C-285(f),
C-291(a)(b)(e)(f), the presence of number plates or yellow triangle markers
does not change the indications of signals.

                                    signal is dark, proceed prepared to stop
                                    at next signal until it can be plainly
                                    seen that indication of next signal allows
                                    train to proceed.

Rules 296 and 297 are used for bracketed signals used on signal
bridges, or adjusted according to fit the situation needed.
