Victorian Ideas on overlap protection, dating from the initial loops at
Rock and Drome.  Thats why the Western CTC has 100m overlaps beyond the
Departure.

Actually, I suspect a driver seeing RRY on an arrival thinks "cross" not
"low speed", so what happens if a driver motors into a loop one day and
finds another train already in the loop?  Could argue the train
controller should have warned the engineman, but I don't think thats
exactly 'best practice'.

Overlap etc.

Rockbank, the Up home unusually has a full target around the 'c' light
