Here are some more pics from Vincent Chan's 'eye in the sky':

The night pic of 4 December shows the concrete pour (to sleeper height) in progress.

The 'Filling' pic shows the crushed concrete being spread on 5 Dec - this morning. It will be rolled in to just below rail height.

Final Pic looks across towards Domain Rd.  The actual road is between the trees and the buildings at right and is covered with construction sheds.

The closest track leads to Park St, next track is the 'mainline' north up St Kilda Rd, first track behind the big vent shafts is the southbound 'mainline' and trck beyond that is the track leading to Domain Rd.

You can see that the crushed concrete fill is in place at left on the closest track.

Mal Rowe - looking forward to a ride in a couple of weeks
