The Annett Keys are not secured in anything other than a padlocked box.

I'm currently inspecting the facilities in Queensland, plenty of facing
points secured by nothing other than a hand locking bar & padlock...

Most Points in TO territory are secured by Master Key Locks, and the
Driver of each train is issued with a Master Key, the Number of which
is recorded on the Train Order.  Some sidings however, (non-passenger
areas only) have only HLB's though.

The Switchlock (is it fully commissioned yet?) is configured so when
the finger trigger (??) is pulled out, the repeaters are replaced to
the warning position Y/Y but won't release the switchlock until a 5
minute run down has occured.  The repeaters do proove the points.

But were the sighting points & braking curves adequate?
