RRL quadruplication - a query for those in the know

 
  Toby Esterhase Station Master

I understand that the Regional Rail Link between Deer Park West and Werribee West Junctions was built with its eventual quadruplication in mind. (Indeed, Infrastructure Victoria's recently released 30-year strategy calls for it.) I recall reading here that the road-over-rail bridges were built so that the space for two additional tracks can easily be 'punched through' the embankments. There's also that large gap between the station building and the current up platform at Tarneit station: if you demolish the current up platform and rebuild it right next to the station building, you can fit two additional tracks in the newly-created gap.
What I can't work out for the life of me is where those two additional tracks will fit through Wyndham Vale station. Does anyone know? Or is there no 'passive provision' for quadruplication through Wyndham Vale at all? (Which sounds to me like a dreadful cock-up.)
Before you answer, I know that the cutting is much wider right at the station - but I understand that that's to accommodate the terminating platform(s) for the eventual extension of the Werribee Line. What I can't see at Wyndham Vale or in the cutting either side of it is how you can fit all of:
- the two current RRL tracks;
- two additional RRL tracks; and
- two Werribee Line extension tracks (which I presume are to continue north of the station to the massive electric train depot slated for north of Ballan Road).

Only 2 RRL tracks (as of now) and 2 Suburban tracks (with heaps of stations) are planed between Deer Park and Wyndham Vale.
But all a long way off.

Some talk of a new direct high speed route between Manor and Southern Cross Station (for a 35 minute run between Melbourne and Geelong) but exact plans are unclear !

Quadding of the track from West Werribee to Laverton, all Werribee services to run via duplicated Altona, quadding from Altona junction to Newport then tunnel under the Yarra through Fisherman's Bend then connecting into Metro 2. Many, many years away however.

The original plans for the 'bells and whistles' RRL had quadding of the track from Sunshine to Wyndham Vale, with a flyover near Robinsons Road, however as we know the funding was cut and we now have RRL lite.

V/Line was never the intended primary operator to Tarneit and it's planned to become METRO train operated at a future time with the tracks looping back to Werribee on the downside of Wyndham Vale.
This is the reason the level crossing at Werribee Street North needs to be grade separated even though the crossing is currently only used by SG services and in case of emergencies and stoppages on the RRL.

Understand all of that but none of it quite answers my query. Assuming the road-over-rail bridges and Tarneit station are built to allow for quadding (and the reservation generally is wide enough for it) why is Wyndham Vale station apparently not?
As I tried to explain, is there room for six - not four - tracks (two original RRL, two additional RRL and two Werribee Line extension) through Wyndham Vale station? Or do the two additional RRL tracks become the two Werribee Line extension tracks at Wyndham Vale station? If so, where is there the room to terminate Metro trains on them?

I don't know where the additional RRL tracks Idea comes from between Deer Park and Manor ?
No point of having more than 2 RRL tracks along that route !

Wyndham Vale station has the provision for 2 extra platforms for suburban trains (on the East side)

From the original plans that I remember is that the suburban lines from Werribee will terminate at Wyndamvale with two platforms to be built. The main reason there is no room now except at the station and under the bridges is the rock is extremely hard and the excavation was extremely expensive. Just to the North of the station will be a 32 road storage and maintenance facility for Metro trains. From Wyndamvale to Deer Park junction there is room for only 3 tracks under the bridges allowing for a local freight line to be built if required. Ceva is a large freight company which has conveniently set up shop right beside the line with many more company's to come.   There is also dual gauge near the GEB sidings at Sunshine so I believe this will run through 4 plat then separate after Anderson road and run beside the line towards Tarniet thus making it 5 lines from Sunshine to Deer Park Junction. 2 RRL 2 Suburban and 1 S/G. From the GEB it will run to Brooklyn and connect with the existing standard gauge.

My understanding is that the spans of the bridges were all four tracks wide, with the end of the support ramps being just a facade that can be knocked out to widen it. Of course, I probably read that here so it could very well be wrong and I'm happy to be corrected if it is.

With extra stations to be build at Truganina, Sayers Road and Davis Road, more tracks would be useful to separate stoppers from Express trains. Otherwise, unless the next generation rolling stock has some incredibly fantastic accelerating speeds, times to Geelong will blow out like crazy.

You may be right, but at the moment there is 2 tracks and an access road between the concrete abutments.
The original plans for Wyndamvale had 6 tracks. 2 Metro platforms. 2 V/line platforms with 2 express roads in between allowing for express services. It will become congested no doubt but when they get enough rolling stock you could have your express services followed closely by the stopper. The turn back at Wyndamvale has a 80k set of points out of the siding and signalling permits those trains to get to the platform quicker.
