V/Line has been a real mess since January. On Thursday 14/1 it was announced a large number of V/Locity carriages were being pulled out of service due to an issue with wheels.
The result was lots of cancelled or shorter trains, meaning delays and crowding, particularly in peak hour.
Publicly at least, it’s still unclear what the root cause is, but it seems that contributing factors might include:
- Tight curves on the overpass between North Melbourne and Southern Cross — but note that overpass actually came into service some 18 months before the rest of Regional Rail Link. You’d think the problems would have been seen earlier
- high-speed curves along the RRL route to Geelong adding to wear and tear
- V/Line not adequately applying lubrication to wheel sets
- most V/Line trains no longer traversing Metro tracks (where, I’m told, lubrication is done) since June when the full RRL opened
- a huge increase in kilometres since RRL opened, but inadequate maintenance
More serious than any crowding or delay issues is that some shorter V/Locity trains may failing to trigger level crossings. Again, speculation is rife, but it seems to be related to the types of track circuits used on much of the Metro network. This resulted in V/Locity carriages being banned from most Metro tracks, with many V/Line services either terminating on the city fringe, or being replaced by coaches, causing huge disruption for passengers.
Apparently the problem isn’t new — it’s been known about for some years, but rather than spend the money and fix it, it seems running longer trains was seen as a suitable workaround. Until now.
The government reaction is to have announced that axle counters would be installed on the relevant Metro tracks — which is good.
And they announced a period of free travel — which is bad. It’s not helping regular V/Line passengers by having extra people on the trains while they are at reduced capacity.
By the end of the month, V/Line CEO Theo Taifalos had resigned, but of course that doesn’t solve the problem.
Investigations continue into precisely what’s caused the problem, and apparently lubrication is now being applied, and lots of wheels being checked and replaced as needed. Let’s hope they get to the bottom of it quickly.
Apart from any specific technical problem, there’s a sense that V/Line has had some trouble adjusting from being a regional rail operator to being a hybrid regional/commuter rail operator — heavy passenger loads, crowding, and high-frequency train services perhaps are just something they don’t really have the expertise in (though Theo Taifalos would have; he previously worked for Queensland Rail).
For a simple example, witness the mess that is the Geelong service: on weekdays trains run every 20 minutes, but with a myriad of destinations and departure platforms at Southern Cross — this makes it very difficult for a passenger to navigate their way to the platform.
Regional Rail Link design
The Age is reporting that the issues really started with cutbacks made in 2010 to Regional Rail Link. The Age has documentation that supports this, something about it doesn’t quite add up.
Firstly, design elements such as re-using the North Melbourne flyover (with its tight curves) were decided well before then.
My notes show that by May 2009 (when the project was funded by the Federal government) it was already planned to use (but modify) the existing flyover, rather than build a new one.
In fact I found this note from 14/5/2009, which pretty much describes precisely what got built: the existing flyover … (will) be expanded or otherwise modified to take some of the regional trains directly into platforms 1-8 without conflicting with metro movements
Once confirmed, PTUA raised concerns about it privately with the Regional Rail Link Authority in mid-2009, because using the existing flyover would mean bypassing North Melbourne station — meaning no interchange for V/Line to/from Loop trains. Discussions at the time confirmed that it had been decided earlier, indeed before RRLA came into being.
(I’ve been told that RRLA and similar authorities such as the Level Crossing Removal Authority are strictly delivery organisations. They build what they’re told to, in the case of RRLA, by the government/Department of Transport.)
PTUA also raised the issue publicly in early 2010.
Around that time, RRLA said they’d review the decision — and apparently they did study some options for a second flyover but ultimately rejected it in 2010. It might be this consideration that was ruled-out, rather than a reduction in the scope of the original design, which never included a new flyover anyway.
Certainly by September 2010 it was locked-in — the EES documents released that month show the design would use the existing flyover:
Secondly, some seem to be implying that the overpass itself is to blame for V/Line’s wheel crisis.
Speed and interchange issues aside, there should be nothing inherently wrong with having curves on a railway, provided they meet the relevant track design standards, and the train operator agrees to the design.
If subsequently the trains are not maintained in such a condition to use the track, then that’s obviously a problem with the train fleet, not a problem with the track design.
Are we really going to build railways with no sharp curves or turnouts from now on, because V/Line can’t or won’t do wheel lubrication? Somehow I doubt it.
(By the way, the XPT derailment there was actually an issue with a turnout — eg points — rather than the curve itself.)
We still don’t know the full story. And large numbers of V/Line services continue to be replaced by coaches — if you’re hoping to use V/Line, head to their web site and check the service changes for a list.
More important than the blame game is identifying the precise issue and how to fix it permanently.
This is obviously an unfolding story. Hopefully it’s resolved soon.

Update: Correction — The Age FOI document said scope changes happened in 2010, not 2011.
Update 4/2/2016: The government says a “stable” timetable (with about 80% of train services running as normal, and the rest replaced by coaches) will start from Monday. Trains will no longer be free, but train-replacement coaches will be. Fair enough. But it sounds like they still don’t know the root cause.
Update 5/2/2016: With regard to who was responsible for RRL design changes, The Age has published this clarification:
The Age reported on Wednesday that Corey Hannett, former chief executive of the Regional Rail Link Authority, made a series of scope reductions to that project in 2010 that have contributed to the current V/Line rail crisis. Mr Hannett did not make the scope changes. The decision was made by the Department of Transport and approved by V/Line, Metro Trains and the state government. The Age regrets the error.
