East Hills line confusion

 
  Colonel Leon Junior Train Controller

Location:
I am confused while looking at the DKRD for the East Hills line. The section of line I am talking about is the quad section between Reevsby - Woli Creek. Reevsby has 4 platforms, 2 of which are located on the outer (main) lines, and 2 on the inner (local) lines. But, all the other stations only have 2 platforms (according to DKRD) which are on the local lines. The two local lines become the Airport line and are served by Woli Creek lower platforms. But the two main lines that go on the Illawarra local lines don't have platforms at Woli Creek. The two main lines don't have platforms at stations Woli Creek - Padstow.

Why is this? I can't recall freight on the East Hills?

The quad between wolli creek and revesby was done in 2 stages.  The first when the airport line opened, only wolli creek to kingsgrove was quadded. The outer tracks were used by express services going via sydenham.  Many years later, kingsgrove to revesby was quadded.  Before this upgrade, revesby got 3 platforms as part of the clearways program, then it got 4 as part of the quad  and was meant as the interchange point.   the outer tracks are only meant for express services that go via sydenham, so there is no need to have platforms.   No platforms means less cost, and greater assurity that trains won't hit the platform edge.

The illawarra local lines at wolli creek don't have passenger services scheduled to travel over that tiny portion, they have crossovers so all scheduled passenger trains use the illawarra mains, only freight travels straight through. This keeps illawarra services separate from east hills and bankstown services.  Again its a money thing, but also it was have required alot of extra engineering and construction to add an extra 2 platforms that saw little use.

In a nutshell, the two outer tracks are the express tracks.

That's why there are no other platforms after Revesby for these tracks. No need, no stoppee.

The Up express track approaching Wolli Creek 'hangs a left" and head towards Sydney on the Illawarra locals.

From Sydney on the Illawarra local,  the Down track crosses over the top of the Wolli Creek pair of tracks.

--------------------------------------

Note that there are turnouts after Turella so that trains using the express tracks can cross to the Wolli Creek line (and vice versa).

--------------------------------------

Meanwhile.

Approaching Revesby from the south-west there are two tracks. (Up and Down)

The Up track splits into the (left-side) island platform (#1 & #2)

Standing at Revesby looking toward the city, left to right are the Up Main (Platform 1), Up Local (Platform 2), Down Local (Platform 3) and Down Main (Platform 4).

Since 4 platforms at Revesby, East hills has little more than one or two rail clearing trains that terminate. During track maintenance, more trains may terminate at East Hills. Note the relative positions of EH station and the Georges River.

Since Revesby now has almost all of the terminating trains, shouldn't the line be renamed the Revesby Line?

Platformless tracks also exist on the Main and Suburban Lines between Redfern and Burwood.

Also Beecroft on the NSFL.

The East Hills line is actually now called the new main south line.

There is no NSFL. The third track is electrified and can be used by passenger services. It is not a freight line.

Why is the East Hills the new Main South? Freight doesn't go there.

What has freight got to do with the line being called the new main south. Freight from the south has it's own route into Sydney these days and the new main south is a designation of Sydney trains for that line.

Yes, I see your point. But a line with both freight and passenger would probably be the 'main' line. But I could be wrong.
Who told you East Hills would be the new main South? Why is it the new main south?
  simstrain Chief Commissioner

The new main south is the route the XPT, Xplorer and Endeavour takes via Sydenham, revesby, glenfield to macarthur. The old main south is called the old main south from granville to glenfield.

And the old old main south went from Granville to Liverpool.

simstrain
No its not.   The airport line is technically called the "new southern line"  But thats only the bit from central to wolli creek.
There has been no changed to the names of the physical lines.  It is still the east hills line.
While it is the main route that trains take, it is not the a mainline, it is still a branch.

What has Beecroft not having a platform got to do with anything. It is electrified and can be used by v sets and X's on express services to the central coast and also for empty trains to Hornsby. If it was a freight line then why was overhead put in?
  Colonel Leon Junior Train Controller

Location:
According to the diagram, it is a down relief that turns into a freight line at Beecroft which turns into a down relief at Epping. I assume it's the line used by freight and intercities/express to Hornsby or Berowa.
The metropolitan freight line is electrified from Campsie onwards.

Because the project was called the Northern sydney freight line, it is predominately used by freight.  Who said a freight only line had to be unelectrified.
  Colonel Leon Junior Train Controller

Location:
No one. But (stating the obvious) freight is usually hauled by diesel locomotives. As overhead isn't needed, why did they put it there?

I my opinion, the line would be occasionally used by express EMUs.

yes, exact reason, used by some scheduled services and used by central coast/newcastle services when there has been a delay.

It wasn't called the northern sydney freight line. It was called the epping to thornleigh third track and it was part of the northern sydney freight corridor which was a series of projects to help freight and passenger trains move more efficiently through the north of Sydney.

It was built by and is maintained by Sydney trains and unlike the SSFL it is not a freight line regardless of whether freight trains use it the majority of the time. The line is essentially a passing loop for north bound trains but it has a dual purpose and is used by express passenger trains to bypass all stops services and also in the case of bypassing a broken down passenger train.

The metropolitan freight line has overhead but it has all been decommissioned and has no electricity. It is also a legacy system from a time when we used to use electric locomotives in Sydney.
