Tonsley Line to be upgraded

 
  Milkomeda Chief Train Controller

Didn't see this posted anywhere else but the Tonsley Line is to be upgraded as announced from the budget. Tonsley Line will now have double track and station upgrades at Clovelly Park and Tonsley and a new bus interchange to be implemented.

Personally I think this money would've been better spent towards the Oaklands overpass.

"duplication of 600 metres of the Tonsley rail line"

What purpose will the duplication of 600m serve? or could it just be a first step in a duplication of the complete line...

Duplication through Clovelly Park will allow a 30 minute service as I understand it. Duplication of the whole line would need to consider Mitchell Park, check it out on google maps.

Even a 20 minute service frequency is already possible on the Tonsley line as it is with only one track, the current Noarlunga/Tonsley line full timetable (replaced by temporary timetables since February last year) already has Tonsley trains running at intervals as short as 20 minutes during the evening peak. My hunch is that this is for a 15 minute service designed primarily to get rid of the many through buses to the outer suburbs which clog up South Road and Goodwood Road.

Four trains an hour to/from Tonsley and four to Seaford would be a good standard off peak service, with two of the Seaford trains stopping at Kesville then everywhere from Woodlands Park onwards and the other two running a faster schedule to Kesville, Woodlands Park, Oaklands Park, Hallett Cove then all stops. During the peaks there could be extras added going all the way to Seaford or starting/terminating short at Brighton, Noarlunga or even Hallett Cove Beach for a few to go straight to/from stabling at Lonsdale.

I can see the problems with trying to duplicate the full length, it would be possible with a very tight fit if it was built with the same lateral clearances to other properties as the current single track line, but I'm guessing that the standards require more generous clearances than they did 40 years ago and that electrification won't make them any easier to fit. But for such a short segment so close to the end of the line, the single track solution should be more than adequate as it would be in effect quite similar to just having a really long set of crossovers outside a terminus station.

I'm more interested in the how the bus interchange would pan out. There's not a lot of space to the north of Sturt Road on the current Tonsley station site, and the southern side would be more convenient for buses to approach it down off Main South Road to the interchange and to depart along Sturt Road and Marion Road to any one of the SExy, Main South Road or Flagstaff Road. That would require pedestrian-activated crossing lights or a footbridge, hopefully a cheap and cheerful footbridge with a simple Colourbond roof providing shelter from the rain.

I personally think this upgrade is to go towards upgrading the line even further in the future like extending it to Flinders Hospital/Uni. There was already speculation last year that the Tonsley Line could permanently be closed due to a lack of people using the line but if they intend to upgrade the line one would assume they are seriously considering extending the line through to the hospital/uni otherwise this upgrade would be pointless.

As stated in the AdelaideNow article "The Tonsley Park Public Transport Upgrade is priced at $63 million, with only half offered by the Federal Government."
The question is will the State Government match the funding in it's upcoming budget?

well I think that the tonsley line should be duplicated and extended!

Mitchell park station rebuilt, Clovelly park station rebuilt on the opposite side of the Alawoona level crossing, tonsley station should be demolished and the line should be extended across Sturt road and then around the sharp corner past the police station, across laffer drive and then over a grade separated main south road (road underpass) to the first stop of flinders medical centre just north of the flinders medical centre staff car park. the line shall then continue across the flinders university sports fields, over university drive, across the baseball oval and then terminating at the flinders university railway station in car park 14 adjacent shepherd's hill road.

this alignment is best as the terrain is flat and the only major obstacles are a few sports fields and an on-ground parking lot.

stations:
Mitchell park
Clovelly park
flinders medical centre
flinders uni

distance between the medical centre and uni stops; 5 to 600m

major structural engineering required: main south road underpass so the main road is not blocked by frequent train crossings!

So are they still planning to build the new interchange between sturt and south road like proposed a few years back?

Guess that all depends on your definition of 'flat'.
  steam4ian Chief Commissioner

Unlike some here I think the money to duplicate 600 metres could be well spent. A relatively cheap fix, 10s of $M compared with 100s $M to upgrade the Gawler service..

The most effective place is at or near the junction so that down Tonsley trains don't have to queue on the down main waiting for an up train to clear the branch.

The biggest failing of the Tonsley service has been its relative infrequency and lack of after peak services. this latter problem could be temporarily rectified by buses from Woodlands Park operating into the evening and at weekends. I have at various times found the Tonsley service most useful, drive from further south then catch the train; about the same or less time than a peak hour drive.

Clearance for electrification near Mitchell park will be an interesting exercise. The fence must be in the OHCLDZ!

How well do you know the area Heath? Car Park 14 would be about as useless a location as you could possibly get for a stop serving Flinders University, being right on the edge of the Sturt Campus (not the more important central campus) and for the bulk of the university even your FMC stop would be closer.actually further away from the Flinders Central precinct (let alone the northern and southern ridge areas) than your suggested FMC stop would be. The location for the FMC stop you suggest would also be silly, if it's going to be used by people with disabilities it needs to be close to the hospital itself rather than dumped out beyond the double-stack car parks.

I agree that an extension to Flinders would be good, but it would be better to do it as a more straight line elevated over Flinders Drive to a station south of the current FMC bus interchange that would serve both FMC and the University. In that location you could construct an entrance into the south wing of FMC right off one end of the platform, and the other end would be very close to the pedestrian underpass leading to the University. Tonsley station could be replaced with a new elevated station over the southern edge of Sturt Road with the buses underneath and a multi-storey park-and-ride in an excellent spot for access to/from the SExy, Main South Road and Flagstaff Road.

I don't think they'll be having too much trouble with vegetation clearance along that section at least!

Doesn't happen to mention when exactly they plan to do this/where this duplication would be? The only two things that could happen with 600m of duplication is to basically turn Tonsley Junction into a copy of Woodville/GMH Junction for the Grange line, so as has been mentioned, Tonsley trains can come off the main line and wait around the corner to enter the single track.

Other than that, there could be a provision for a passing loop and duplication at Tonsley Station in preparation for a future extension?

Adding a second track at Tonsley station does not necessarily indicate preparations for a future extension. When a train gets to the end of the line it takes a few minutes for the driver to change ends and get going out the other way again. If there are two tracks at the terminus there can be another train waiting so that as soon as one train arrives the other can depart making a slightly faster service. This is the process that is done at Lilydale in Melbourne.

Saying this I believe the most useful bit of duplication would be at the northern end of the line as mention so that the mainiline is not blocked by a train that has to wait to go down the branch.

600m of track is not much more than a siding. It is hardly "duplication".

It's a bit sad when such a small bit of additional rail infrastructure gets a political announcement. Such small teaks to the system should be day to day.

I suppose we are even sadder for discussing it.

It's a crossing loop. Plain and simple. It'd be nice if the money could be released fairly quickly so that it could done as part of the existing shutdown would be even better.

Yeah, but there is a possibility. I'm well aware of driver turn arounds being a driver myself. Same situation applies at the Entertainment Centre on the tram line, but this was left as such for possible/planned/shelved extensions of the tram line, hence my suggestion.

In any instance, I think the most likely scenario is going to be a Woodville junction style duplication at Tonsley junction, and a passing loop somewhere probably between Mitchell Park and Clovelly Park.

But its all speculation regardless until we see the plans for it.

Additional to this is the amount of signalling changes required on the line to change it from Single line automatic block signalling to CTC working as the Belair line is (providing a crossing loop is being installed)

I think that this could be the likely scenario that is going to happen with new electric trains whizzing along on the mainline you do not want them held up by a service that goes to Tonsley. As at Woodville two trains can arrive and depart separately for Grange at the same time and both mainlines are kept free if needed for a through run. The Grange train coming into Woodville can be held at the signal as does happen often and the Grange train can still depart to Grange.
