Victoria has allowed running crosses on CTC (and ATC) without any problems,
this action of preventing running crosses on ARTC Track is just an over
reaction as the result of the Hines Hill collision.

Human error caused Hines Hill, if we are going to over react to every
incident by banning things we may as well stop running trains. Before this
accident running crosses were the norm on the South Line CTC.

The crossing Loops in NSW in general are so short it would be almost
imposible to do a running cross, (how long have they been forbidden in NSW)?

The speed proving on the Victorian Western CTC effectively prevents entering
the crossing loop (either track) at high speed as the signal will not clear
until the driver proves his speed to 40 km/h at the Arrival Clearing Board.
Of cause I realise red signals don't stop trains, drivers do,
(sometimes)<G>. but the speed proving, as much as it is a pain, does force
speeds to be low when performing a running cross.

PS. Even the MET (Bayside) do running crosses on the Cranbourne line.
