So, news has come in that a small part of roof, near the gangway has exploded off a Waratah. Another problem with these trains. I have a feeling that UGL haven't done a great job at all with the M and A sets.

EDIT: Well, someone has made a mistake. It is clear to see, as the Waratahs launched far later than their release date and when they did launch, there were technical issues.

It was on the news, happened at Burwood station, loud bang around 1:30pm. A piece flew off and injured a man (minor injuries to chest). Some said it's lucky it wasn't peak hour otherwise there could have been serious injuries had it gone into a crowd of people. Which A set was it?

According to the NEWS footage taken (directed to in the first posting of this thread), it was set A8, car N5508, 3rd car in direction of travel towards Central.

Why blame UGL?
They didn't build them and don't maintain them.
Maybe Downer made a a mistake, but more likely Changchun got it wrong...

Sounds like a short circuit in the high tension side of the power equipment.
Losing the covers isn't a big problem. Bad luck for the passenger in the way,,,

And given the set has been running for several years now, it's unlikely to be an original manufacturing defect. More likely routine maintenance didn't clean something that should be regularly cleaned.

It will take a while to get the report if the ATSB has been called in, they have their hands full with bus fires Smile

Get your info correct first before commentating on what happened. UGL have nothing to do with the M and A sets, they are maintained by EDI.

As far as I know this is the first incident of this kind to occur to a waratah.

What are the "problems" with this set? They have amongst the highest reliability rates in the fleet.

No particular problem with the set but a minor problem with some electrical equipment in one car. The A sets are extremely reliable as will be the new B sets.

So it's official - the new Waratahs will be branded "B" sets? I saw the announcement back in December that new Waratahs would be coming although that the differences will be relatively minor - basically more advanced air-con system, more destination indicators inside, improved security, etc, more or less a Waratah Mk II. Just wondering if anyone knows anything more about them? Also, will the new batch allow for the last of the S sets to be retired?

What is exactly wrong with the M sets and Waratahs?   I know about the small software bug, what what else is wrong with them.   They are the smoothest trains I have ever been on.

Please don't harp on about how the seats are uncomfortable or the Air con isn't enough.   They those aren't flaws with the overall design.   (air con could be fixed by adding buttons to doors, so every door didn't have to open at quiet stations)

The new batch will retire the S sets. There is talk of a later additional 36 car order (after the 24 batch of course) which will replace the K and C sets which will then mean no more silver sets.

It is a matter of a fact that the air cons on the A sets are overpowered and are wasting electricity when doors are opened.

It was a traction inverter module that failed. These are built by Hitachi.

They actually vary power based on a lot of factors. Passenger load, outside temperature, inside temperature (measued at multiple locations in each carriage). Modern air conditioners are much more efficient too. They probably do draw a little more than older sets at full load, but in most circumstances they don't need to.
