ARTC signalling Newport to Gheringhap

Just wondering why the ARTC is so erratic at setting green signals for trains. Two examples. Anakie loop (up end) they set the signal to green for SCT,s 6PM9 at least an hour in advance. This happens regularly but why so early? Example two. Laverton loop (down end). I'm on a Werribee bound spark & i observe a down red signal for the Standard Guage as the train passes the loop. A few KM,s down the track & not five minutes later, Aurizon's 7MP1 come through seemingly given the green signal at the last minute. I totally understand that in both cases there are no trains coming the other way but why is this early/late signalling happening?

Not familiar with  Anzac Loop ?  The loops between Newport and  North Geelong C are  Laverton Loop,  Manor  Loop and Elders  Loop .  Then double track North Geelong "C" to Moorabool, then single track with the next loop at Gheringhap.

Do you mean Laverton Loop - the loop just on the Up side of Laverton - not Anzac Loop?

Laverton Loop is the boundary between the ARTC Plains CTC Network Controller and the ARTC Melbourne Metro Controller. Routes don't get set through Laverton Loop until both Controllers are ready for the train.

The signals at Gheringhap Loop vary. Sometimes the signal will change one hour in advance, other times as little as five minutes. I haven't taken notice to any pattern. I always head up to the track 20-30 minutes in advance to see a train.

It's not just at Gheringhap loop, it also happens at Laverton & Anakie loops as well if you read my first post. Your right to arrive early at a specific location, but the only downside to that is you could be waiting for an hour or more thanks to premature green signals. It's strange how the signals change to green sometimes, but as long as the line is clear for the section the train is travelling in that's the way they do things unfortunately.
