I should add that actual train transit times at the moment would be less while drivers get used to handling the train, which from my seat they are being cautious. But a straight pull up the hill is certainly faster. I do not know yet, if they run at 80KPH with the loaded caustic on the front. I havent paced it yet to confirm, but it did seem that way.

Spotted a couple of P class pulling a rake of XU(??) wagons heading north along Roe highway around 5pm. What would these be doing?

There are now seven DBZ locos back in service.  It is planned to swap out the DFZ locos at Albany with DBZ class over the Anzac long weekend.

Lol those DFZ's probably racked up more km getting there from Geraldton then what they did down there.

Does Aurizon know what their doing?

ACN41XX is pulling 9 caustic wagons on the mainline to Alcoa. A bit over 4hp per ton for level track Confused

Aurizon have a video online about their iron ore. Not a bad viewing :

I really like near the end when the iron ore is dumped from the wagon, something I never thought of, is the wagon jumps up and down with the shifting of weight.

Pity there arent more videos of the technical side of railways, such as the fitting of the wheelset to the traction motor. Very cool stuff. Unless I'm mistaken I'd very much like to know about them. The DVD's I have are all external viewing of operations.

A rake of XG coal wagons have been placed (maybe stored) on the front roads of Picton yard. If they are infact stored this will be due to space issues at Collie I would think. Or, they could be receiving intensive maintenance. Time will tell. Picton container terminal and Brunswick yard are full of rollingstock so they dont have many places to put them. It looks like they cannot use the WACAP siding anymore.

The XM ballast wagons in Brunswick have been looked over by fitters and the ballast pile, while already big, I noticed a truck and semi trailer dumping more material.

The DP consist is still running to Worsley.

At Chullora Bogie Maint Centre we used to have a row of six cradles to sit the wheel sets on . We used to bring a set of traction motors in via overhead crane and fit one half of the split suspension bearings into it . The other halves went into the keeps or outer halves . The motors were lifted into place and the keeps mounted up with four long through bolts . The axle then supported the motor .
The keeps had oil wells in them and into these went the wick pads on spring loaded plates , the suspension bearings had windows through them so the pre soaked wick pad wiped directly on the axle journal .
Then the two piece , upper plus lower , gear cases were fitted with cotton seals and silicon sealant and partly filled with tubes of crater grease .
The quickest easiest ones to do were the Mk2 80 class and 85s 86s . These used roller bearings in tunnels that bolted directly to the traction motors . 442 Mitsubishis may have had them as well , was doing this 25 years ago so details escape .
46s were the most awkward , messy hand tied wicks and huge ungainly motors .

I imagine that plain journal bearings, the shaft could be repaired for scoring or wear between the axles without pushing the wheels off? With roller bearings the wheels would have to come off for a bearing replacement. Or is that not a big deal to push the wheels off? I cant see split race bearings being in there.

Did this kind of work happen in a clean part of the shop?

As a lathe operator I would prefer a shaft without wheels on it so maybe its a non issue.

I noticed tonight on a passing train that the leading end of every wagon has its lifting point painted a purple/ pink colour. I have noticed white paint on the end caps of the axle on one axle only on each bogiep before. I suspect these are connected.

Are AURIZON doing some kind of flange wear analysis? The leading flanges will wear more then the trailing on a bogie, so maybe they are looking at the benefits of a rotation program ?

DB2313 I think derailed in Picton yard today, a crane was lifting it back on tonight as I passed through.

It wasn't really clean or dirty , so no sand or grit blowing around anyway .
It wasn't very often a complete wheel set axle assembly had its suspension bearing journals turned and rolled . Generally bogies came in for reco because of worn wheels so everything was disassembled meaning used wheels pressed off and scrapped .
I used to fit the bare axle in a lathe and re-machine the wheel seats and suspension bearing journals , the latter were rolled to form a smooth surface .
New wheels had their hubs bored to match so they had the correct interference fit .
Every so often there would be a screw up and I remember one day they had a wheel pick up on its seat in the press and it naturally gouged the shoot of of it by the time they got it back off .
They asked me to turn that journal down to just short of condemning size even though I knew it wouldn't clean up . Then they said machine it further even though I told them the engineers would never let it run . I did they didn't and got growled at anyway .
At one stage our section came under notice because a series of reco bogies were getting hot suspension bearings and they blamed us . They said we were screwing up the bearing tolerances when we knew we weren't . So the engineers came out and watched us doing what we did best and couldn't fault it . Eventually they discovered that the traction motor bearing keeps were being faced too much and the spring load wick pad assemblies were bottoming out on the journal and wiping oil off rather than on .
Again this was approximately 25 years ago so it's someone else problem now days .

I would have thought the bearing journals for the TM's would have been ground for better accuracy/ roundness etc. I understand rolling gives a better material structure though. I have an old Timken bearing book here my grandfather gave to me, that refers to rolling of the axle, although not of the journal but of the stress relief groove I think. I will have to read it again.


Did they use lubricant for pressing the wheels on? I recall reading about Tallow as a lubricant to aid pressing. I can imagine what the shaft looked like having seen a few press fits go bad, or heat + cool fits go bad, end up in the press, and go bad yet still.

2819 is working the south west main again.

Anyone know if there was a signal failure or otherwise yesterday afternoon / evening. 3 trains were in Brunswick at one time, two heading north, one south. Seemingly no good reason for it.

What appeared to be a signal failure in Brunswick provided some great train spotting today, with over 8 trains seen within 2 hours. At one point there was 5 trains in the area

I noticed a few weeks ago the rake of BAUY flats at Brunswick had disappeared, then tonight I noticed there had been a mass clear out of BAUY's from the Picton Container Terminal including those one the dead end at the western end of the yard, thus leaving only the XOA hoppers, though they have also been move 1 road back.

Have the BAUYs been relocated, scrapped, or shipped back to Qld??

Are these weapons defective or old or just not required ?

Not required, they are air braked skeleton wagons brought over to replace the QU's. They havent been used in 5? years, some years now anyway, due to rails inability to compete with road transport.

The JP? oil wagons are being broken up too by the looks.

It would be sad to have the XO woodchippers cut up, final nail in the coffin for the Greenbushes line. I do hope their smart enough to salavage all the screws and nuts for the doors from them to use on the ones still in service in Albany though.
