Almost identical to the master clock(s) that were used to synchronise 
the British Railways station clocks in about 1980. A 48v 1pps was 
distributed by private wire to many stations and platforms. Keeping all 
of the clocks in synch was a full time job.

As a young hard up engineer I recall being quite jealous of the engineer 
who got paid overtime twice a year to manually do the daylight saving 
correction :-)

It was replaced by a new system with digital displays on the platforms 
and I kicked myself years later for not keeping one of the old pulse 
clocks for posterity.

Regards Paul
