- Exterior of the maintenance shed from the Karrabin end. There are five tracks through the shed. Road 1 is the lifting track, with under floor mounted jacks which can lift a six car train and then lower the centre of the jack to disengage the bogies for service. Roads 2-5 with raised tracks for under train inspection and elevated working platforms for roof working. The overhead solid conductor (25kv) has isolating sections at each end of the shed for safe working. To the left of the main building is the Wheel Lathe building on road 8, which can reshape wheels without the need to remove the wheels from the train.

The first new train has arrived at the Wulkuraka Maintenance Centre 3.25pm Friday 19 Febuary 2016, pulled by 2 diesel locos.

Re: Wulkuraka Maintenance Centre
Are they side destination boards near the doors?

Re: Wulkuraka Maintenance Centre
Yes the trains are to have side destination displays. The Wulkuraka Maintenance Centre is next to the much upgraded Wulkuraka station, second station from Ipswich and runs almost to Karrabin station There is no public access to the Maintenance Centre.( there was only access on the public open day before the NGR train arrived)
Re: Wulkuraka Maintenance Centre
Testing of the first NGR train continues.

Re: Wulkuraka Maintenance Centre
I found information on it through a simple google search, despite also having spent some 22 years living there. I guess Google must be new to a few people here.Wulkuraka Maintenance Centre

Re: Wulkuraka Maintenance Centre
Why do they need such aerodynamic noses on suburban trains? And why are the brakes so radically different to trains before it? They seem a bit exposed. Interior looks nice.
A pity Sydney doesn't have trains like this .Queensland are lucky they aren't tied down to a 1960s double decker concept and are free to obtain normal trains according to world best practise.

Disc brakes, narrow guage=less room between the wheels=put them on the outside.Swift wrote:And why are the brakes so radically different to trains before it?
Not uncommon on standard gauge trains either.

Why don't they employ conventional shoes pushing against the wheels ?

What's the advantage of having those things added on when trains have slowed down fine without them before!ajw373 wrote:Because this is 2016, not 1956!
Even buses are overkill with disc brakes!

Re: Wulkuraka Maintenance Centre
Cars stopped ok with drum brakes before too and I am sure you will agree that these days having a drum brake fitted car is a little bit daft.Swift wrote:What's the advantage of having those things added on when trains have slowed down fine without them before!ajw373 wrote:Because this is 2016, not 1956!

The biggest advantage of discs on a train is a greater surface area, meaning you need less brakes per train and they are more efficent. They also help to reduce the unsprung weight.
Re: Wulkuraka Maintenance Centre
QR have had problems with wheel slide when braking in wet conditions with the IMU/SMU units causing station over runs and the accident at Cleveland in January 2013( The full ATSB report can be read at https://www.atsb.gov.au/media/4354235/r ... _final.pdf ) and the trains are being/have been retrofitted with sanding gear. No doubt the NGR trains braking performance in being extensively tested.
The NGR units will be the first suburban units to have the coupling device on the ends of the train covered by a cowling, like the tilt train and the Spirit of Queensland. Sometimes the EMU units are coupled two trains together (12 cars) and go though Roma St (to the washing shed?) If this is done with the NGR trains it would be more difficult, needing to remove the cover.

Re: Wulkuraka Maintenance Centre
Mercedes Benz introduced ABS in 1981 on their flagship S class saloons and tbe technology has been standard fare on all cars and many buses and trucks for decades now. I can't see why it can't work to stop the wheels on a train locking up.1of55 wrote:QR have had problems with wheel slide when braking in wet conditions with the IMU/SMU units causing station over runs and the accident at Cleveland in Jacan't see whynuary 2013( The full ATSB report can be read at https://www.atsb.gov.au/media/4354235/r ... _final.pdf ) and the trains are being/have been retrofitted with sanding gear.

Re: Wulkuraka Maintenance Centre
There are systems that do exactly that. But that doesn't help them stop overruns. It would just prevent the wheels locking up.Swift wrote:Mercedes Benz introduced ABS in 1981 on their flagship S class saloons and tbe technology has been standard fare on all cars and many buses and trucks for decades now.

Re: Wulkuraka Maintenance Centre
ABS is supposed to help the vehicle stop effectively in the wet. Why don't I hear of this problem in Sydney's system?
Does this not show that these brakes ate too grabby for train use?

Re: Wulkuraka Maintenance Centre
Disk brakes have been used on trains since the 1980s. They are fitted to NSW trains. See http://www.otsi.nsw.gov.au/rail/Investi ... -final.pdf Rail Safety Investigation Report Derailment of CityRail Service 312A. The braking systems have built in devices to counter wheel slide but the fall back position would seem to be slower speeds and sanding.

The second ngr train arrived at the maintenance centre at wulkuraka at 10 am sat.

Re: Wulkuraka Maintenance Centre
Do we all not reailse that the IMU100/120 series have been using rotor/disc brakes since 1996/1999???
ABS helps prevent overrun by not locking the wheels. Once the wheels are locked, they slide further uncontrollably and more freely aiding in an overrun. ABS limits the amount of brake pressure applied in order to give maximum braking effectivness on the edge of adhesion of wheel to rail.

Re: Wulkuraka Maintenance Centre
ABS works by comparing the rotational speeds of all wheels on the vehicle, and activates if it detects partial lockup of the wheelset. In a car, say, the front wheels lock but the rears don't.
It can have a problem if ALL the wheels lock simultaneously, because it can't tell if the vehicle is stationery or not.
