Color light designations: R = red r = small red S* = flashing (color S) Y = yellow y = small yellow S+ = flashing alternately with Sx G = green Sx = flashing alternately with S+ B = blue S? = on or dark due to failure V = violet U = lunar white u = small lunar W = white N = number (projected or light grid) X = letter(s) (projected or light grid)Mechanical signals: Most mechanical signals have been replaced by colorlight signals, but a few remain in use. A number of mechanical speed (TIV) and direction indicators are still in use, since the application of projected light indicators is fairly recent.
Mechanical signal and fixed board designations:
blk = black
tan = tan (light brown)
red = red
yel = yellow
grn = green
blu = blue
vio = violet
wht = white
ltb = light blue
S = any light of color S as above
color1/color2/color3 shape "symbol"
color1 is the color of the symbol or text
"*" is used for the case of no symbol or text
color2 is the color of the background
for multiple colors, they are arranged as they are on the board
color3 is the color of the border
multiple borders are represented by hyphens, outward to the edge
"opp" is used to indicate a border around checkerboards that is
the alternate color
this field is blank if there is no border
shape is the shape of the board; for rectangles the longest dimension
is indicated by (--) or (|)
symbol is the text on the board (possibly multi-line), or in some
cases a more detailed drawing of the symbol
Examples:
wht/blk/wht-red square "A"
white letter A on a square black board, with a white inner border
surrounded by a red outer border
*/ wht red /opp square board
red wht
a square checkerboard of four colors, red border where the square
is white, white border where the square is red
When mechanical signals are shown, it can be assumed that the clear
form will be white when the spectacle is rotated away, unless
otherwise stated. Similarly, for 1941 code signals the entire light
cluster is shown in the standard arrangement and it may be assumed
that the clear form consists of the green or lunar light, unless
otherwise stated.
