Tonsley Upgrade Thread

If this is true, what about the Crows match at Adelaide Oval on 20th April? Footie tickets valid for free travel on the N4?
"1S47"
AFL match tickets already include pre-paid travel (it's not free, it's a levy included in the price of each ticket) on any regular Adelaide Metro services as well as the additional Footy Express trains and buses, so yes they definitely would be valid.

I would hope that the plan for the 20th would be to have DEMUs terminating at Woodlands Park station from the city with the buses only doing the Woodlands-Brighton segment, in order to cut out the most congested segment of the Adelaide-Brighton bus route. This method of working (substitute buses over a short distance) would then become the ideal solution with every weekend featuring a short closure (substitute bus journeys no longer than 10 minutes) for regular maintenance somewhere on the rail network, instead of simply putting up a TSR and leaving it for a capital project.

So where do you turn back then?

At this point, Wayville, Goodwood and Oaklands, Brighton and Noarlunga are points where turnbacks can be organised without Pilot working at 25km/h. Woodlands would be fine, if the Tonsley Line was available, but that is where the possession is.

If Diesel Working only, Oaklands wouldn't be an issue thus keeping the Oaklands - Adelaide closed, allowing the possesion to take place. On the other hand, if it were to be run by Electric+Diesel, Brighton would be the logical termination point as the overhead traction power needs to be isolated. I believe this can be done at or near Hove. As far as I am aware, the next isolation point is actually at Ascot Park (and I'll be pleased to know that I'm wrong).

I thought there was a crossover to be installed north of Woodlands Park station during last year's track rebuild work. Do you have information suggesting that this part of the work did not take place?

Wasn't there also a crossover near Clarence Park previously? Did this get removed last January and not rebuilt?

No crossover at Woodlands. Can't see one. I took this photo on 5th of October, last year and I've taken a few trains in between. No crossover at Clarence Park either. Nearest one is at Wayville.

If there was one there it would've gotten removed so there was room to install the concrete masts I don't remember there being one there but I could be wrong.

Justapax.

In the 1980s double cross overs 9facing and trailing were installed between Clarence Park and Emerson, on the up side of Oaklands and on the up side of Hallett Cove, Bi directiona signal heads were installed at the down end of Brighton and at Hallett Cove. They were never commissioned and had their heads turn across the track only to be removed during the recent upgrades.

The Clarence Park cross overs disappeared early, Oakland became a single trailing cross over and Hallett Cove lasted until about five years ago.

There never was a cross over of any sort at Woodlands Park. Long before that Edwardstown, Oaklands and Brighton had cross overs giving facing and trailing access to the respective goods loops. Brighton only had a trailing cross over at the up end because at the down end the track became single; two trains a day reversed at Brighton, I recall one was the 5:18 ex ARS.
Brighton yard disappeared with the new station and duplication to NC and Edwardstown went about the same time. Oaklands yard persisted and what remains is a rump of what used to be there. The facing cross over at the down end disappeared when the line was extended to NC and the new signalling was installed (not the new new signalling).

Ta, so operating to Oaklands is a viable option then.

... And with car parking and bus facilities nearby along with a turn back siding Oakland's is the best option Smile

The crossover at Tonsley Jn was used during the track rebuilding and level crossing work to transfer vehicles between the down and up tracks.  It was the only location between Goodwood and Marion to permit the transfers.

Working to Woodlands Park would still be possible if only two railcars are needed at any one time between Goodwood and Woodlands Park by running trains on alternate tracks.

Will the line be ready for electric traffic when (eventually) it opens?  You'd presume so.

I think that you will find that the Tonsley electrification is complete except for powering up.

This afternoon a consult of 4 engineers was seen at the N end of Ascot Park platform.  It could be that the junction trackwork is fairly imminent.

I'm not expecting the Tonsley branch to open as double track from the junction for some time, I'm hoping I am wrong though.

From the mainline you can see the final signal on the Tonsley branch has been placed in the middle of the tracks however there does not appear to be sufficient clearance on the track alignment that is not currently connected to the mainline at the junction, so initially at least it may open and run in the same manner as prior to it's closure as single line working. Sure they can move the track to provide more clearance but I would have thought it would be easier and cheaper to move or replace the signal with an overhead one if both tracks were to be used in the near future.

If (and that's still a big IF) that's the manner in which it opens I wouldn't expect the junction to be upgraded until much later in the year or over the Xmas/NY period.

Maybe someone in the know can confirm or 'scuttle' my suspicions?? If the junction pointwork is built offsite then where would they build it before transporting to location, and also considering the local streets in the area are quite narrow and offer limited clearance except from Daws Road along the right of way perhaps?

Somebody here with a reasonable likelihood of knowing what they were talking about said the cross over wasn't wired. When I looked about two week ago it didn't appear wired to me and the wire was to one side of the down track suggesting it might be moved where it connects to the main.

The Tonsley line only needs DEMUs to get it going. A single DEMU set can only get a single trip per hour so for a 30 minute service two sets are required, this would get it off the ground even if it is only an interim timetable. A fifteen minute service would need the duplication in service and take 4 sets.

I agree that the line is currently signalled for single-line working (see http://www.railpage.com.au/f-p1897922.htm#1897922).  It's the lack of rolling stock that has precluded the restoration of the service.  The signal base for the up line seems to be in place.  My observation of engineers today together with work I saw on the signalling cabinet a week or two ago suggest an earlier rather than later date for the junction trackwork.

The Wayville crossovers and the Millswood S points were assembled in situ from sets of component parts unlike the Nairne Jn crossovers which were pre-assembled and lifted into place with heavy cranes.  The overhead at Tonsley Jn would prevent such a crane lift.  The attached photo shows pointwork assembly at Wayville in May 2013.

According to Rod Hook on ABC 891 yesterday morning the Tonsley line is due to open late April.

I'll believe it when I see it now this Tonsley Line reopening is reminding me alot of Duke Nukem Forever a game that was repeatedly delayed until it was released over a decade later.

Was any more detail given?  I was aware that that he was to be on but didn't hear the entire interview.

Several people have already said that the junction is being done at Easter time, if that is true I would guess April 28th for Tonsley resumption.

Considering how much you "rabbit on" and the tolerance shown you here I don't think it falls in your court to declare a thread "sewn up".

The Easter Shutdown, if it occurs, has not yet been announced and from discussion here would seem to clash with the rail service for the football.
