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(i.e. a dark target) [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.
