Melbourne Suburban Disruptions (Since Metro Introduction)

Glad not travelling to Heidelberg today

Buses will replace trains between Clifton Hill and Heidelberg due to level crossing equipment damaged by a motor vehicle at Fairfield. Buses have been ordered but will take time to move into position. Please listen for announcements or speak to Metro Customer Service staff for more information.

Real drama and action today at Fairfield on Hurstbridge Line when a driver was caught on the level crossing and backed up when the booms were down and smashed the boom



Trains were stopped and buses called but just after buses were arriving the trains were running again.

Drivers details handed to Police.

Cancellations on the Craigieburn line this morning 4/5 with a possible new excuse. No it wasn't wet, windy or hot. It was cold this time that caused the chronic signal failures.

Major signal fault at huntingdale. Pakenham trains delayed 90 mins. At least

Metrotrains Melbourne - Can't cope in the heat of summer, Can't cope in the chill of winter....

a mess

All this is bad enough for rail passengers but does anyone measure the chaos to literally hundreds of thousands of road users too or does no-one care about either rail or commuters?

Presumably they don't have these sort of faults and delays in the town of Denial where the minister lives. Wouldn't it be nice if even just once she was caught up in this sort of chaos. Twisted Evil

That's why they have 'Lexus Cages' (cough) taxpayer-funded chauffeur-driven cars to isolate them from the real world...

Just ask Steve Herbert MP (or at least his pet dogs).

Signalling meltdown at flinders street causing 30 minute delays on most lines.

Also issues due to a power surge affecting the morning peak.

It just keeps going on and on with the downtime.
  Carnot Chief Commissioner

All Metro services were suspended this evening based on a police request. I wonder what all that was about?

Trains are back moving but with long delays...

It was a person on the flinders viaduct.

There are about 500 very unhappy and over 75 mins late stuck at Westall. Trains were cut short to save late running.

Not happy

And to cheer us up another express just ran through (the second) as pakenham don't stop.
They can terminate a train but not get an express to stop

Metrotrains are having another meltdown today:

Glad I am in Thailand on holidays.

Take a look at this mess for the hurstbridge line

Delays to over 60 minutes due to a computer failure affecting the metropolitan area. Trains will hold at available platforms until further notice. Please listen for announcements.
Passengers are advised to please defer travel where possible, or seek alternative transport.
  Carnot Chief Commissioner

Uber are already increasing their pricing....  Looks like a Metrol meltdown.
  712M Chief Commissioner

All trains on all lines stopped until further notice.

Inconveniently the PTV and MetroNotify apps are currently down (presumably due to high demand).

Whatever happened to redundancies? Without knowing more, I'm just speculating, but (1) if this was a hardware failure, there should be redundancies to take over (this should extend as far as a complete secondary control centre that can take the load in the event the primary control centre goes offline) and (2) if this was a software failure, the problem should have been caught in testing.

The computer failure has shut down the entire network, according to the map on the Metro website.

I take it Metrol hasn't been replaced like it was supposed to be?

I don't know what happened, but as a general rule it's impossible in software to test for every single thing that could ever go wrong, and there is no such thing as a bug free program.  There will always be something out of the blue which no one ever thought of.  Programmers have a saying:  "Murphy was an optimist".  Having said that, there could perhaps have been better handling of an unknown error.

Of course - I totally agree. It's impossible to check for every single possibility. However, one is supposed to design software to degrade or fail "gracefully"; if you don't implement proper exception-handling, then your program can just completely crash (and possibly corrupt useful data in the process) if something unexpected happens.

The fact that this computer failure brought down the whole network would suggest that there were no redundancies (or they all failed as well) or that the system or software has not been designed with quick recovery in mind if something does cause a catastrophic error.

Edit: The other point to add is that testing should try to cover all the common scenarios in which a catastrophic failure can occur and test the system's ability to handle and recover from them.

Crowd control measures are in place at Southern Cross and City Loop stations. Please allow extra time to enter the stations and follow directions from staff.
