(rail transport, UK) A type of railway signal which shows the aspect of a signal ahead of it, normally used in a situation where the main signal is hidden from view, for instance where there is a curve in the track.

Banner-Repeater signals tend to be provided in locations where drivers receive insufficient warning of the main signal, thereby effectively increasing the sighting distance for the main signal.
