Descriptive labels for railway signals

"Descriptive labels for railway signals" can refer to several types of plates, most commonly railway signal identification plates that label and identify specific signals with codes.

Descriptive labels for railway signals: These are used in railway systems to identify specific signals. They typically consist of an alphabetical prefix followed by a number.

Railway signal description plates provide information on signal identification, track location, and the intended route for a train. They can include a signal's specific number (like R173) or a prefix code identifying the route, and direction (e.g., CA54R for a distant signal).

The tag ref=# is used to describe a variable signal table and contains information about the direction, type, function, and order of the signal. In different countries, the label "code" is compiled according to national carriers.
