Newcastle realignment

[dbromage@fang.omni.com.au (David Bromage)]

According to "sources", this is the current thinking for the realignment
of the Newcastle line.

Mt Colah: minor curve easing

Mt Kuringai: major curve easing

Mt Kuringai - Berowra: 1 in 66 gradient tunnel to Hawkbury River

Berowra: through station underground, possible truncation of existing line
for terminating suburban services

Hawksbury River: Existing causeway, tunnels and bridge

Mullet Creek: major curve easing, new trestle bridge to Woy Woy tunnel

Woy Woy - Gosford: major curve easings, may include Woy Woy relocation

Gosford - Lisarow: major curve easings, relocation of Narara and Niagara Pk

Wyong - Morriset: minor curve easings

Dora Creek, Awaba: 2 routes under consideration for Hawkmount

Fassifern - Teralba: 3 routes under consideration for Fassifern Bank.
Favoured option moves Fassifern 300m west.

Cardiff - Kotara: 2 routes under consideration for Cardiff Bank

Signalling upgraded with provision for 200km/h running.

Cheers
David
