I was busy so I didn't get a real good look. I did notice that the track still crosses the road near St Puis X High, then the new tarred path sweeps over the track. It looks like the track is buried under the asphalt.
I don't know how far down the line the path goes, or whether the tunnel under the Pacific Highway has reopned.
When I checked out the line in detail in Nov 2001, the tunnel was closed due to an 'accident' of some sort - no further explanation on the sign, and the track was still in place until Whitebridge (I think).
The line detoriorates badly toward Belmont, with very little still present. Some clue to the one time station at Bemont is 'Railway St'.
It is a pity that they have tarred over it - perhaps one day they could have reopned the line, even as a tramway - there is a lot of new housing development out there.
