Well, that seems to make sense then. The original question was "Why is there
an extra signal 2 km down the track in SA but not Vic. Obviously, the Vic
Rules and Regs permit a train to resume normal speed once clear of the
points whereas in SA, you must remain at medium speed until the next signal
is passed. Hence the need for an extra signal in SA. Vic's idea is cheaper
but is it safe?
