on the antenna? How are clocks synchronised on the real railway?

In the early 1960s the Didcot railway telephonist would connect via the
omnibus circuit to all teh signalboxes between there and Swindon just before
1100 each morning - and at 1100 would call out 'Time Time Time'. The
signalmen would then adjust there clocks (and, AIUI, had to record this in
the Train Register. Subsequently the signalmen would liaise with station
staff to regulate station clocks.

From the early days of the Irish Mail the train's guard was handed a watch
at Euston each evening - to enable the Queen's (or King's) time to be taken
to Dublin
