Certainly the case. Ballan, Longwarry, Broadford, to name but three, had
repeaters that were regarded as two pos signals..

 I reckon that these should be called point indicators. They do not, like
proper signals, regulate the passage of trains. They merely give the driver a
visual indication about the state of the points.

This was made possible by the abolishing of the rule, a little while ago, about
distant signals having to be arms. After the rule was amended (or maybe to
facilitate it) South Geelong got up and down light distant signals.

Merely point indicators what ever you call them otherwise.
