Technical and geekboy question : How many notches for braking and traction on the 4000 series power controller ?

The public are also going to have to be trained (pun intended) to enter and exit trains promptly. None of this waiting until the train stops to leave your seat. This will reduce dwell times.

Yes, I agree steam4ian.  Every aspect of dwell time should be considered: padding schedules is extremely costly in capacity terms and simply slows the journey down.  I have been on London Metropolitan Line services where dwell time is 7 seconds; 14 seconds is typical - and these are relatively long and well-patronised services.

Modern Bombardier EMUs generally have four power notches and three service brake notches (plus emergency) so I imagine they would have gone with the standard kit they churn out in Sweden rather than going for a bespoke version for a tiny order of just 22 units.

If they have gone for an bespoke version we're in trouble, Bombardier multiple units with variations from the tried and tested kit have a shocking reliability record during the early stages of operations.

Saw a 4000 EMU passing through Oaklands (Morphagonal level crossing) at 2150 heading towards Seaford.
Looks so good, modern and long.

There was a test run this afternoon I saw 4001 at Mile End was this an unscheduled test to see how they perform under heavy rain?

Heavy rain in Adelaide?  Must be a relief after all that heat.

There probably is a requirement somewhere to test 4000's under different kinds of weather and see how it goes with braking etc; also, you don't want to find out later on that they leak like the Ford Capri did...

Just wondering, will 2 A-City sets coupled together (6 car set) be tested?

Yes it's from the tropical low that was at the top of Western Australia a few days ago with rain forecasted to continue till tomorrow already at 25mm of rain today with it set to continue gonna be plenty of call outs for minor flooding. The visibility over daws and Marion road bridge was like 15 metres earlier so much spray hope the emus are doing well in this weather.

I hope so! would be great to see a photo of that, especially going across onkaparinga bridge..

I'd expect the implementation required some kind of acceptance testing in heavy rain, low visibility etc.  On a project of this scale, I'm sure it didn't just boil down to someone saying "hey we should take it out for a run in the wet..."

Not that I know of such matters, but couldn't it also be possible that the contracts with Bombardier had clauses stating requirements for wet weather running and other such rainy-day cases.

Funnily enough in my company (software) when we do functional testing, we often refer to different test scenarios in similar terms, e.g. a scenario that's expect to perform under optimal conditions with no errors we refer to as a 'sunny day case'; coding for exception cases or bizarre configurations is often referred to as catering for a rainy day!

Did they break 4002 today? It was out testing this morning/afternoon, but has subsequently been seen under tow to DC. Seems slightly odd if it were to be towed to DC today that they would have been using for testing early today to sub out for another.

I don't think there'll be much reason to test two 4000s together, I cry much doubt they'll be running them as coupled sets. Presently there is little call for more than three cars on the NC, with the increased frequency I don't see coupled sets being needed. That's all before you consider platform lengths...

I too would hope that heavy use is made of this weather which is rather rare for Adelaide at this time of year. With a 95% chance of rain tomorrow there will even be time to plan out some runs for testing "non-standard" operations like one EMU rescuing another, and/or familiarising drivers with the performance in the wet.

Maybe 4002 just needed some additional miles to get to the next warranty service point.

I'd be very surprised if there was, given the apparent lack of any requirement for them to deliver the EMUs on time. 13 months after we were told "they're coming in a couple of weeks" and then one full unit every fortnight after that and we only have 5 of the 22 units!

Time for a quick service before its starring role in the PM's opening of the Seaford Line maybe?

How about after every Adelaide Oval AFL match and on the premier faster peak services if they return? Granted, the football won't be such an issue for Port Power games, the first trains could start leaving halfway through the third quarter and return to the city in time for the people leaving after the finish.

As for platform lengths, Bombardier confirmed in a presentation at some industry event back in 2012 that they would be fitted with selective door opening. It remains to be seen as to whether it is unit deselect or carriage-level SDO, and whether it is activated by GPS position (not good - these units are an Electrostar under the skin and their GPS systems are useless) or platform end beacons which I have yet to see at Oaklands, Marion or Mile End (the only stations too short for two units if I remember correctly).

However, just because 6 car trains will be needed doesn't mean the department is going to run them. I didn't see anything in any of the documents about the project which indicated that a tender had been put out for a customer service ethic to be imported and installed.

I doubt it was broken since it was under its own power towing 2 DEMUs to ARS but it definitely looked to me the 4002 was bound for Dry Creek though since it was towing 2 DEMUs

Could have been the opportunity being taken to understand the wet weather performance of an EMU rescuing DEMUs and vice-versa.

Drama at Raglan Ave today, the crossing was down and there was a new train stopped at a red signal at Woodlands. The crossing was eventually opened.
  justapassenger Minister for Railways

How unfortunate, two days of rolling stock problems followed by signalling issues the next - and the brand new signals at that.

Tomorrow is the beginning of Fringe-Fest! And as soon as the trains go public, they'll be crammed!

Just to clarify a couple of points...

1. Every weekday this week, there have been planned (ie: In the train notice, timetabled) runs of EMUs from Seaford to ARS and return for Driver training. Adhoc runs after 2100 every night.

2. 4002 was stuck due to a power failure related to the weather. It was pushed to ARS by 3000s, then put out onto 104 road until after peak when the power was restored. Not being towed to Dry Creek as far as I'm aware.
  Milkomeda Chief Train Controller

Well when I saw the 4002 its front lights were on it definitely looked like it was under its own power and not being pushed by the DEMUs

It can do that off its batteries. The question is overhead traction power. There's a video on Facebook but you can't see the panto. I'd suggest if it had failed or there was no OHP, the panto would be down and the push would have been coming from the 3000 class behind it.

Right click -> view image on mclaren2007's photo above, the panto is down.
  steam4ian Chief Commissioner

Can any informed person tell us more about the power failure?

What ventilation is available from the battery back-up.

A crowed train on a 40 deg day with out open-able windows and no air con would have people smashing glass or forcing doors open.

Good thing we had some 3000s to push 4002 out of the way.
