Suburban Rail Loop (Election promise)

I don't think it's a different track gauge (is it?) but certainly there was talk of it being 25,000 kV AC as we have here in South Australia. You don't need nearly as many sub-stations as you do with 1,500 V DC but yes, it ill be incompatible with the existing suburban network (without dual voltage trains).
SRL won't share any tracks with mainline trains, so I'm guessing that it will be SG and 25kV AC, maybe even 3rd rail. Gonna be interesting to see.

"guessing" ???

We went thru all this last December.
Page 14 section 3.1.5 definitely 25kV AC

Even without knowing who will build the rolling stock, its certain that they will be built at Ballarat, Newport or Dandenong. All BG.
Can't rail anything on SG

So why on earth complicate the project by having to deliver every completed set, and return every set for major maintainence, on the back of a truck?
Delivery of HCMT and Xtrap show how it's done, without power (so voltage doesn't matter)

PS a fully equipped train carriage is too big for road travel anyways, without a very specialised route.

Yep. Incompatible electrical system and possibly a different gauge.

Interesting but no drama.

Airport to a major junction station that offers routes all over greater Melbourne is fine.

If SRL is a stand alone loop, how do you propose transporting carriages from Dandenong, ballarat etc and into the tunnel. E.g. diesel to Westall and then special transport to Heatherton stabling yards.

Generally curious how they would do this. Maybe there will be some small connection to the main network on the Dandenone line?

a standalone "line" can still have chords to the existing network (assuming track gauge matches).  Case in point, Sydney Metro Phase 1 / Old Chatswood-Epping link - the tunnel dives (from the north) are still connected to the metro track (underneath running roughly E-W), it's not in operational use, but it's still a pathway between the two isolated networks.

edit: and this can theoretically be built into the new airport station going ahead as part of MARL - in future a point could be built to connect both the SRL and MARL tracks (I fully suspect the MELair station to have four platforms built as part of the MARL project - just 2 will be in use from day ops in 2029 etc with space for easily inserting P2 of the standalone SRL 'line')... again not for everyday operational use, but as a pathway to connect two isolated lines if there's ever a need.

edit x2: anyhow, heavy maintenance will probably be done at the new maintenance facility in Kingston.... I'd have thought.

Agreed, always thought that Westall is the ideal connect between the 2 networks. About 500m of tunnel would do it.
That's Eastern anyways. Out West, SRL will eventually surface next to the "real" trains.

I doubt major engineering, aka a very big factory, will happen at Heatherton.
Local angst is growing, so stabling and cleaning/minor fix is likely to be the max space/aggravation that will become the compromise.

The government will just need to add a station and hand out money for parks to keep the locals quiet. Westall isn't big enough to cater for SRL. Expect a Pakenham East sized depot in Hetherton shrouded in parkland.

Hertherton will be above ground, fitted out cars could be delivered on trucks from Newport and joined before beginning testing.
Dandenong will be tied up with Next Generation regional fleet, whatever that is. Ballarat will also be busy with Xcrap 2.0 and someone still needs to build the 100 new next generation trams that were announced. Next 10 years are going to be busy for local manufactures, even more so if federal labor is elected. Buying cars from CRRC will be a no no.

Minor problem with your analogy.

The Heatherton site is only about half the size of Pakenham East.

Westall may be OK to maintain short (4 car) SRL trains, but it's real benefit is easy access to the rest of the network.

Perhaps Melb surburbs might put up with an initial road disrupt for deliver of 100+ rail carraiges
- move power lines, trees, signals - you name it, very high load on a truck will hit it,
- traffic shut downs
but regular to/fro for the next 100 years, is not on.

Location: Melbourne
Sydney metro's facility just beyond Tallawong station - 6 car trains - measures approximately 30 hectares via gmaps.  

The Heatherton site:

- approx 34 hectares from the houses (western end) to Old Dandenong Road ("Henry Street" the northern boundary)
- approx 47 hectares if you utilise the above plus the strip of land between Old Dandenong Road and the Dingley bypass as well.

Sydney Metro P1: 36km, 22 x 6 car trains, 4 minute peak frequencies.  All maintenance done on the one site.
SRL P1: ~24-25km, roughly same amount of 4 car trains, probably same type of service pattern - much more room to play with re: land/putting facilities in the one place.  What the locals think of it is another story but it passes the pub test that everything will be self-contained if we compare to SM P1.


And anyhow, from Engage.Vic: https://suburbanrailloop.vic.gov.au/-/media/Project/VicRoads/SuburbanRailLoop/Planning-page/Suburban-Rail-Loop-Stage-One-Project-Outline.pdf

"The Southern Stabling Yard would include stabling and maintenance for all trains on SRL Stage One, an operational control centre and associated facilities such as train wash and substation."

There's only going to be a need to get the vehicles in there in the first place, no ongoing movements elsewhere.

A brave statement, Minister.

So ...  Xtrap don't make regular visits to Ballarat. HCMT, not even fully operational yet, have been seen returning to Newport.

In both cases, there are maintenance facilities at their respective stabling, yet not all required work is possible there.

The trains will most likely be imported for SRL and maybe fitted out here at best. As they're not going to be broad gauge. Government can reduce costs by making them SG and there's no valid reason for them to be BG, none. The SRL is being sold by the VLP as a new wholly separated network.
  Jordy33 Locomotive Fireman

For them (SRL trains) to be imported would be quite politically risky, if VLP and ALP manage to get power. Albanese likes the idea of building trains in Australia, to import trains would be contradicting a potential federal labor government. It doesn’t seem as the liberals are as fussy about building trains in Australia (looking at NSW).

Either ways, what we need is an effective import option (from a friendly country), an assembled in Australia option, and a fully built in Australia option. It’s effectively spend less but into other countries, or spend more but the money is largely spent within Australia.
  John.Z Assistant Commissioner

The SRL trains will be built here from imported car bodies using local parts like every other train and tram since the X'Traps.

But yes, I see no reason why it wouldn't be SG.

Why build a connection between a SG line and a BG network? Just do what is done in most places in the world, deliver the rolling stock by road to the depot. Much quicker delivery process as at least the shipping to Oz by ship isn't required....
