How are clocks synchronised on the real railway?

The original digital ones were synched to "Rugby" (now located at
Anthorn in Cumbria).

Analogue ones are increasing synchronised to the "correct twice a day"
source, popularly known as "stopped".

The second picture on this page:

Shows a tuning coil at Rugby, which I think was the one for the time signal.
Low frequencies tend to require large coils, but I've never seen anything
like this.

Cop this one then :-

now recycled by the Russian navy.
