A bit of an update on the progress of the duplication works to Melton:
The level crossing at Mt Cottrell Rd has been altered, with the Northern boom gate & flashing light assembly relocated and the track laid through the crossing. So far, I think* this is the only crossing that has been done, Hopkins Rd, Troups Rd North, Paynes Rd and Ferris Rd still require this work. Hopkins Rd will be the most difficult, as this is a fairly busy road so it will probably be a Saturday night/ Sunday morning overnight job, that said, from a technical point of view they should all be fairly straight forward.
The bridge over the Toolern Creek at Melton has been built, with the deck now in place awaiting the installation of track.
The laying of track has begun along most of the line, with different sections in varying states. In some sections it looks completely laid with a healthy amount of ballast covering the sleepers, in other sections there is nothing but the foundations for the track bed. The foundations for the track bed have all been built, with the only exception being the majority of the level crossings that still need work. As of yet, there is nothing connected to the existing stub of track leading Westward from Caroline Springs platform 1.
As reported by other users on this site, a new turnout on the down side of Melton (past Coburns Rd) has been installed but as yet, there has been no work done between this turnout and Melton Station. The current track layout at Melton has the current mainline running through the station, then taking a tightish banked curve out towards the Coburns Rd crossing (down side) while the passing loop line continues on into a refuge siding to the North of the mainline with a crossover to the mainline immediately after the station platforms. For the duplication to continue to the West or Down of Melton towards the new crossover the siding will need to be abolished and replaced with a new banked curve matching the current mainline.
*I say I think as I'm not sure whether or not Troups Rd North has been done yet, the others I listed have certainly not been done. Troupes Rd North has been closed to road traffic for the duration of the works.
