Danish Signaling, Indicators

Updated 000111

General use and appearance

An Indicator is a signal that provides route or speed information in addition to a "proceed" (or similar) aspect. Indicators display symbols, letters or numbers and are usually of the "theatre" type, i.e. having a number of lamps that can be illuminated in different patterns. Recent designs use fiber-optics in a similar manner. Older designs are different.

Route indicators come in 4 variations:
Route direction indicator (danish: Retningsviser), in use 1935-1953.
Route destination indicator (danish: Bogstavviser), in use from c. 1925.
Track number indicator (danish: Talviser), in use c. 1925-1971.
Information signal (danish: Underretningssignal), in use from 1977.

Some of the types mentioned above are used stand-alone as Route display (danish: Tableau).

Speed indicators come in 3 variations:
Symbol speed indicator (danish: Symbol-hastighedsviser), in use from 1953.
Numeric speed indicator (danish: Tal-hastighedsviser), in use from 1988.
'X' indicator (danish: X-viser), in use from c. 1985.

An indicator is usually affixed to the post of a main or route signal. However, it may also be found next to the signal or on a separate post. A few examples of signal/indicator combinations are given below:
