Now Metro Trains finding themselves with reportedly similar issues to that of Vline.

Reports also suggest Qube have similar issues on their Maryvale Goods container wagons.

The crisis deepens.  Having a good day minister?

Public Transport Crisis Continues: Metro Trains find thin flanges on their rolling stock wheels

The entire rail management in Victoria would be battling to organise blowflies into a country dunny after a picnic race meeting.

One of our regulars said earlier that Victoria's Granville is just a matter of time. He's looking more and more prescient by the day.

This must mean metro trains will need to remove rollingstock from service to fix?

I ask again where is the Rail Safety Regulator in all this and what (if anything) is he/she doing about it.

How often are wheels checked visually - much less gauged properly?

The Hitachis might not get another life, but the drongos who presided over this fiasco probably will.

Nope. Costs are too high just to bring them back for a brief stint in revenue service. Besides that, I'm thinking this wheel flange issue could be caused by the curves approaching Springvale station, considering both Metro and Qube are reporting problems too

That was I that is forecasting a serious accident and I will stick by those words, the way Australia's political system is now ONLY a serious accident or a catastrophic failure of the transport system will produce any change. There are plenty of precedents out there for this senario.

The problem does end up back with the people, they are to tied up in there own lives, overseas holidays, large houses, two cars, large screen TV's etc to care about anything else. The politicians getaway with this behaviour in the end because WE LET THEM.

To be fair, have you ever tried to organise blowflies in any loctaion??!!

Yep - I would spray the lot of them starting with the biggest ones (the red and blue ones of course).Smile

What happened to the grease pots, were they removed when concrete sleepers were installed?

As for a rail greasing train, it's not like "Harry the Greaser" is going to be riding the rails any time soon (which for all we know, it could be sitting there rusting away in its faded yellow until 2030, if it isn't "donated" to Sims Metal by then). Maybe it's time to fit the old greasing gear to IEV102 or another MTH car if they don't use rail-based grease pots anymore...

Oh yes, herding cats, now there is an exercise in futility!

Exactly, because you can't have a herd of cats.  There are various other collective nouns for cats, some not very nice, but "herd" is not one of them.

You can't even lead them on a leash..

Ours are surprisingly happy on a leash...

Meanwhile, 9M is believed to have derailed its trailer at Rushall. The week is getting better and better for PT...

A Metro Train has derailed today at North Fitzroy could this have been caused by the flange issues?

could be one of many issues lets just wait and see hey

Unconfirmed comments from witnesses were that there was a possible braking failure of some sort, all unconfirmed. See pics in the Vic Forum

Except Springvale wouldn't explain thin flanges on Xtraps. seeing as they don't go there.

Hi @ShaneB how would brakes cause the derailment?

Does the office of the transport investigator need to attend and determine the cause?

That bend is the biggest across the whole network because it was part of the 3 way junction of the Inner Circle railway once run by the smaller steam engines whose trains include shorter carriages during the 20th century. Either the wheels' flanges are worn out to paper-thin sizes or the train went too quickly around the bend could've caused this. Metro should at least bank this section of track so trains will least likely derail at tight bends such as this one.

Purely speculation on my part.  We do know for certain that the gauge on concrete sleepers used for RFR and RRL was made tight.   We have heaps of low profile sleepers on the Metro combined with quite a number of new station sites and grade separation sites also being concrete sleepered.   Maybe ok to have "tight" gauge on tangent track but with numerous quite tight curves on the Met network is this tight gauge and the absence of rail lubrication now starting to impact.  I was made aware of this issue some months ago but the cumulative affect may now be appearing.  And whoever proposed the "tight" gauge in the first place, was it comprehensively researched and trial sections on both tangent and curve track comprehensively tested before making it the new standard!!!

Heap of potential causes:

  • Speed
  • Wheel condition
  • Rail condition
  • Sleeper condition
  • Track buckle
  • Any combination of the above
  • other factor(s) etc


Wait and see what the investigation finds.

Tight gauge is a big NO in any circumstances. Sad
