***STOP PRESS*** VLocity cars withdrawn from Bendigo line

 
  The Vinelander Minister for Railways

Location: Ballan, Victoria on the Ballarat RFR Line
This morning, 21/1/2008, due to some VLocity services not activating level crossing protection, all VLocity cars have been replaced by Sprinters on the Bendigo line until further notice.

Wow, what next?

That explains the double velocity on the 0900 South Geelong this morning that is normally three Sprinters.

Is it beyond Sunbury only or all the line?

So did my train from castlemaine to Bendigo, although the Echuca vlocity had to wait for the crossing to activate before it could enter Bendigo station

Would that delay the introduction of sprinters on Stony Point line?

If memory serves me correctly, we went through a similar withdrawal of the Sprinter fleet for *exactly* the same issue. Non activation of crossing protection.

And, I'll stand to be corrected here, the villian at that time was the fluid which was squirted onto the inside of the wheel discs was somehow responsible.

I don't wish to derail the thread, however, does anyone recall this situation with any more accuracy?

Yep I can confirm your memory Smile  It's actually quite common (world wide thing)a new train can't activate level crossing signal.

It's true sprinters coming to Bendigo a nice sight Very Happy
Does anyone know if they will be on the line again tomorrow??


After 7014 went to Echuca


Cheers J-C more to come if they run tomorrow Smile

humour me someone...

why are the VLO's off the Bendigo run..only now ?

were they working last week, and not now ?

they were tested on this line werent they ?

all seems a bit odd to me .

cheers

Sprinters are lighter than VLocities so why VLocities aren't activating signals/crossings is a weird problem.

So that would explain all the sprinters I saw on the Bendigo Line today!

You don't really think they are too light to set off the circuit, do you?

It is not a weight issue, it's more of an electrical issue. Tracks have a very small electrical current through them for signaling and gates. Either side of crossings there is a rubber placed between track ends which breaks the circuit. When the train runs over it, it creates the circuit therefore causing the gates to go down. Weight has no issue.

I must have just edited it before you posted, sorry about that. Somebody brought up that it was sue to them not setting off some level crossings or that so I brought it up.  Wink

When the Sprinter problem developed on the Ballarat corridor, which was an identical problem to what the Bendigo line is experiencing today, the entire fleet had to be modified to include the provision of TCA (Track Circuit Assister) units. The Sprinters have had this modification - the Vlocitys do not. That is why Sprinters & loco-hauled Car Sets were used for the remainder of today on the Bendigo Line. After some testing happens late this evening, more will be known. The ramifications of all this for the operation of the entire Vlocity fleet could be serious. All depends on the outcome of the testing.

Aren't the sprinters and Vlocity's Compatible?

Could they have a sprinter lead each vlocity train until the problem is solved.

I.E. 1 sprinter lead 1,2 or 3 vlocity units. OK they would only  130Km/h better than withdrawing the hole fleet. would make vline terribly short if that happened.
  kuldalai Chief Commissioner

The Sprinters operated for over a year before the problem with activating track circuits first occurred, actually on the Geelong line .

The DMU units are lighter and track incredibly straight compared to a loco hauled where the loco will slop around quite a bit from side to side  . Rigorous examination with the Sprinters revealed that where there were loco hauled mixed in with Sprinters then problems were intermittent, whereas Sprinter only routes at the time like Ballarat were giving consistent trouble . Failing to activate the track circuits created problems with level crossing equipment not working, trains just dissapearing from signalmans display panels, and also operation of auto signals .

With the Sprinters the ultinate fix was to fit a frame beneath the bogie that excites the electrical field and in doing so activates the track circuits.

Whether it is the same problem with the Vlocities is not clear, but if it were one would have thought that the Vlocities would have come fitted with the Sprinter modification .

These type of problems activating track circuits with DMU's were well known Overseas at the time of Sprinter introduction .

Sprinters and Vlocities are not compatible. as originally conceived with a max operating speed of 130kmh the initial spec was that the new DMU's were to be compatible with the Sprinters .  However NX were not keen on the idea, and once RFR came along and the spec was altered to bigger engines and a max speed of 160 kmh the need for compatability largely dissapeared and the two train types cannot be operated together in one train .

When the problem was first found with Sprinters, it was suggested that with all the light weight railcars running, the rail head wasn't being kept clean enough to complete the circuit for signalling, so they ran a rail cleaning train for some time with a rake of VOCX's to help clean the rails.  

After a phone call this arvo, i went out to await the arrival of the 16 15 ex Melbourne into Bendigo with N472 and that grey H Set thing.  Also right on it's tail were a pair of Sprinters with that fugly looking new livery one.

A couple of shots of the N-H Set can be seen at:  http://gunzelgallery.fotopic.net/c853138.html

nice, i left at 5:45 i couldn't be stuffed waiting for more sprinters if i knew that was coming i would of waited Laughing

When do you think they will go back steve?
  emd645e3c Deputy Commissioner

Tomorrow morning i guess.  No idea what train, but i think it's safe to assume it wouldn't be the Flagship one.

Vlocity's are doing Seymour runs.

I don't really know the situation over there - is this an odd occurance for that line?
  DalyWaters Chief Commissioner

Hard to imagine how this can be something that will only occur on the Bendigo line.

Then again, its odd that its taken two years to occur.

After some testing happens late this evening, more will be known. The ramifications of all this for the operation of the entire Vlocity fleet could be serious. All depends on the outcome of the testing.


We wait with baited breath for news on this one.
