It describes the 'banjo' disc signal and calling on disk that you
refer to.


What is the meaning of the white squashed hexagon on many (but not all)

Normally when the train is stopped at a signal for longer than a
specified time the rules say the driver has to telephone the signal

The diamond shows that there is a track circuit giving a visual
indication at the signal box, so he doesn't need to phone in.
