Hurstbridge Line Upgrade Stage 2

Just been through Clifton Hill on the Down this morning, there is nowhere near enough clearance to run the Up South Morang line over the Down Hurstbridge due to both the road bridge and the distance from the junction to the station.

This is what I assume they mean by Untangling Clifton Hill, it is this single crossover that causes all the delays, Dn South Morang is fine, it is just a deviation from the Dn Hurstbridge after the station and Up Hurstbridge is also OK as the Up SM doesn't join it till after the junction (they run parallel for a short distance).

The East side station building and platform are a modern-ish rebuild and ripe for demolition and rebuilding as an island, the old canopy could be re-used as it is a stand alone structure by the looks of it.

I will watch developments here with interest as even though I won't be using Vic Park regularly after next month this has been my hood for the best part of 30 years.

Have been through Clifton Hill many times and have often dreamed of how it can be sorted out...

What about reducing the width the two current platforms and putting an island in between? 4 tracks running directly into the station with the Mernda Up going over the Hurstbridge Down on the South side.  The actual location of the platforms could be moved North if there needed to be more space for the flyover to the South.

If they were super clever they could even remove the Ramsden St LX as part of the process.

Why is Clifton hill the problem now with only two tracks south of that location trains have nowhere to do really.
Just too many trains passing through the junction.   Its fine if everything is like clockwork but when its not it can get hairy.   I'm not sure how many other stations in the country employ a system like park road in brisbane, where trains toward the cbd share two platforms.  Allows simultaneous arrivals on the island platform so the junction for trains heading south can be optimised better.

Exactly Tazzer, under that plan the trains could arrive pretty much simultaneously into a new island platform at Clifton Hill then the Hurstbridge service which runs express Clifton Hill > Jolimont could depart first with the all stopping South Morang departing as soon as it cleared the section (just before Vic Park I think).

Would make for much more efficient running and allow more trains to run in the congested 2 track section from CH to Jolimont.

A no brainer really, I hope that is what they are thinking.

Double track all the way is the only rational decision, EXCEPT.Where are you ending the double track.  Double track all the way to hurstbridge is a waste, its pretty much a country branch beyond greensborough.  Duplication to eltham i can understand, ideally with a 3rd terminating platform.

Sorry tazzer.

I meant to say "all the way per the initial media release" (ie Wattle Glen).

But then again, why not Hurstbridge. Only going to get one crack at this.

Easy to say that Hurstbridge is not that big.
They said the same about Mernda, and it took another 60 years to undo that stupid shut down.

Diamond Creek to Wattle Glen is basically straight, flat and open with suitable width either side - it's very easy to duplicate.

Wattle Glen to Hurstbridge has many more bends, much less room, lots more trees either side and several embankments/cuttings made to keep the railway level as the valley thins out. I'd hazard it's just cost really - if they can get a decent enough service without spending too much money then that's what they'll do.

Another factor is that the terrain between Eltham and Diamond Creek is similar to that between Wattle Glen and Hurstbridge - lots of trees, lots of bends, embankments, cuttings and the like. Running a 20 min service, a Down train leaving Eltham would cross an Up train from Hurstbridge between Diamond Creek and Wattle Glen anyway, so unless they're going to duplicate the whole thing to run a 10min service (unnecessary in my opinion), the section they've chosen is all that's needed.
