Electric trains never break down and need crossovers, they said.
Well done champs!
I didn't think Pt Augusta was shutting down for another week or so?It would need to be operating at full capacity today, it's a calm day with heavy cloud cover
http://www.abc.net.au/news/2016-04-28/delays-on-seaford-line-to-continue-into-the-night/7367698The only thing they don't say is which Lonsdale Sub Station. There is the one that feeds the whole of Christies Beach, etc, including the Sub Station that feeds the Rail System. Then there are a multitude of things that could go wrong in the Sub Station itself. The explosion that was heard could be something as simple as the overload circuit breakers opening. But why they opened is the question. It could be an earth leakage, overloaded circuit, failing Static VAR Compensator, etc. The cause of which could be anything.
Still no cause reported!
At least Adelaide Metro's disruption page says a "Power Outage at the Lonsdale Sub Station"
There is only one Lonsdale Substation, that which is part of the rail network.To be fair, the location of Port Stanvac is Lonsdale.
The other substations operated by SAPN are called the Pt Stanvac Substations.
If, as persons claim, there was an "explosion" the problem would be obvious, electrical things do go bang and they make no secret about it. I have seen cubic CT tanks turned into spheres before the side blew out. My point is, that if there was an explosion then the problem would be obvious. Arranging a solution might take more time, possibly weeks.Can you comment on their explanation of it below? Does a circuit breaker really take 2+ days to replace or are they just trying to buy time?
As a professional in the field my level of confidence in the electrical capability within DPTI has seen little to raise it above the floor level.
Power has been down since approximately 8am yesterday following an electrical failure within the Lonsdale rail sub-station. Investigations to date have determined a circuit breaker had failed. Back up systems will not be activated until a thorough safety inspection and testing regime by contractors is undertaken.
The contractor has advised that comprehensive testing and preparatory works must be undertaken prior to re-energising the system.
Safety remains the key consideration in re-energising the system and understanding the cause of the damage. System testing will take several hours. At this stage we do not know what caused the failure of the circuit breaker.
Adelaide Metro apologises for the inconvenience and thanks passengers for their patience and understanding.
There is a need for a back up feed point.The DPTI report to the House of Assembly Public Works Committee said just that…
The system however, is vulnerable to a loss of the SA Power Networks' supply (such as through major bushfire) or failure of a critical item of equipment. In this unlikely event, loss of traction power and an outage on the electrified rail network will result. Dependant on the nature of the failure, an outage may result in extended disruption or closure of rail services. This system vulnerability to failure will exist until such time as the City Feeder Substation is constructed.
The cheapest option could be a gas turbine generator about 10MW, such a plant would fit on an ISO container base and because it is for emergency only burn dieseline supplied from a convenient tanker.Long term, real redundancy is needed instead of a bodged together backup which could well take the DPTI staff a few hours to get going - or to put it simply, buy nice or buy twice. The top knobs need to get around to realising that this sort of major disruption (which will span a minimum of four peak periods by the end of today, plus two major events if not fixed by the end of the weekend) causes people to permanently lose confidence in public transport.
I like the heading to this thread.It's partly intended as a big juicy full toss for Heath Loxton to hit out of the park. Let's see if he makes the connection or lets it go through to the keeper…
I called in at Brighton tonight to watch 3000 railcars terminating on the middle road where passengers would board or alight. There were seven buses standing by as I arrived.Conspiracy...!!? What are they hiding...?
Leaving just before 6:00, I was a pair of coupled 4000's pass through Hove at 6:03pm heading toward Brighton.
Lots of stories of AM workers using their skill and initiative to minimise what was a considerable inconvenience to all concerned.I did hear one allegation of passengers being evacuated onto the track while there were trains moving on the other lines around them which resulted in a near miss, I guess it was on the Goodwood-City section or the other train was a DEMU rescue set.
As for the fault and the time taken to rectify it I trust there will be an ATSB investigation so that the matter could be in the public forum.I concur - although maybe ONRSR might be more appropriate? The above mentioned allegation would be the ideal trigger for a wide-ranging investigation of Adelaide Metro rail practices which I believe has not happened in quite some time.
I did hear one allegation of passengers being evacuated onto the track while there were trains moving on the other lines around them which resulted in a near miss, I guess it was on the Goodwood-City section or the other train was a DEMU rescue set.And if the person making the allegation is found to be lying.........?
This is an extremely serious allegation, and if true should result in the responsible staffer being fired and prosecuted. Initiative is all well and good, but the staffers need to be confident in their training on how to ensure the other running lines are properly blocked if they are going to evacuate passengers.
