Similar set up has been installed at Essendon Airport recently. Only
instead of rail type boomgates there are full size gates.
No booms or gates - all done through the tower.

Pretty sure there are gates there as well. There was the 4 times I was there
last week.
They were installed but not yet working. Also had amber beacons in place on
the gates.

It would be kind of silly to expect someone in the tower to trust and hope
that every vehicle does not cross because they so and not have some sort of
physical barrier as well.
