Hornsby Resignalling

["Cameron White" <cameron@idx.com.au>]

Apparently only the old main panel of Hornsby has moved over to the new
control room and as it was an old "pistol grip" style frame it involves the
most work to change over to the new SSI style controls.
the new Push botton route control frame is causing some problems with the
myriad of different types of points including the old air slip points and
the new electric higher speed turnouts.

The North panel which controls Berowra to The River bridge is moving this
weekend. hopefully the amount it will work as it is already SSI.
