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.
