Interesting article, if you take it at face value (difficult I know) it states:  At 9am TasRail alerted police about a freight train that was anticipated to derail in the Devonport wharf area.
and further The automated freight train derailed about 9.10am on Formby Road, opposite the Post Office, about 300 metres from the Harbour Master Cafe.

are they operating remotely controlled trains in the Apple Isle?

Yes they are remote operated, although heading north (to Devonport) the driver is normally in the powered loco.  
Heading south the remote control cab is used.

Pretty sure they're refering to the fact the driver can be in a remote driving trailer.  He's still on the train and controlling, just not always from the main locos cab.

Looks like the cement train overran the siding.

So, what is colloquially referred to as "distributed power" an apparent "push-pull" operation?  

Is that how they carry out this operation?

Yes. It's absolutely not distributed power, as there is only locomotive. It's push-pull, with a driving trailer at the opposite end to the powered locomotive. Been running that way for many years. But, does remote control mean that if the train is single manned, the driver can also control the train, during shunting operations, from the ground? That's common in various places around the world.

Its like alot of USA trains, loco is fixed at one end, in reverse running the driver sits at the far end, in this case its an old loco thats been gutted of its traction equipment. Currently DV1 is a old Y class, but soon to be replaced, if not already.

My understanding the train runs with its powered loco on nth end of the train, the loaded direction to port.

How do the Driving Trailers talk to the powered loco?

Remote control,  if I recall correctly, the driver unloads the train at the port standing along side using the remote control.

If Tasrail confirmed with Police 10min prior to derailing, then it sounds like they had a communications failure. However I would have thought the driver could pull the brakes manually, unless of course it was brake failure. The route is only 26km long, mostly flat following the river, so maybe the driver tried to slow up river for a curve or something and no brakes????

The ferry jetty is I think the end of the cement unloading siding, main is behind it.

Question, if they knew 10min ahead, then the train was out of the yard and the derailment looks like it had some speed. So why not continue on the main? Perhaps there was an opposing train?

From the ABC Report :

"TasRail operators were forced to deliberately derail an out-of-control driverless freight train in Devonport, before it went on to injure two pedestrians."

"Police were running and driving alongside the train as it careered along the tracks for more than nine minutes."

"Inspector Stuart Wilkinson said police were drove on the road beside the train as it travelled at about 50 kilometres per hour towards Devonport, with police warning about the approaching danger."

(Emphasis mine)

Taking all that together it sounds as though the driver was left behind in Railton while the train ran all the way to Devonport and off the end of the siding.

Wow, that's a stuffup of massive proportions if true.  
My understanding was the remote control would stop the train if it lost signal from the drivers portable controls, unless the drivers controls went for the ride too!

I was thinking the same thing.  Maybe there was some conjecture as to whether the Don Bank would pull it up.  If it got past there then there'd be nothing much to stop it until it got to the end of the line through Burnie.

Maybe the thought was that the end of the cement siding in Devonport was a better option than the middle of the UTas NW campus at West Park in Burnie.

There is probably also a policy already in place in the case of a runaway and I'm guessing that designates the end of the cement siding as it.  The loco appears to have been directed onto the grass away from the main, so perhaps the siding is delibarately angled that way?  Still, I'm surprised there is not the equivalent of a dead-mans brake on this lash-up.

I seem to recall the old AN Tasrail parallel parking some ZB's on the Don Junction points.   Pity they aren't still around...

A lot of questions to be answered. Be interesting to know technical details of both the concept and the real operation.

TasRail does not seem to have much luck.

I wonder if they still have any of the old HE cement hoppers in storage or if they all got scrapped.  
They may need them for a while to get things going again.

It is amazing only two people were injured could have been a lot worse.

From the photos it looks like 7 wagons off the end of the track.  The wagons on the track are likely to be still all in good order and return to hauling cement ASAP.

Of the ones off the track you will probably find a couple are quickly repairable (looking at photos). 1 to 2 maybe a write off especially looking at one behind the loco.


The biggest concern will be the potential damage incurred to the TR.

The engine turned right due to what evere was in the way and forces behind it. I doubt they would deliberately have a train leave the ROW corridor and cross a walking path.

On a side note a few years back i watched DOO with remote shunting in the terminus at i think Leipzig Germany.

The driver had the train underway and he was saying talking to someone while walking the platform. Hoped on just as he ran out of platform.

The "locomotive" at the rear of the train is the unpowered Driving Platform DV1 (an ex-Y class with engine removed). Trains heading to Railton are operated from that cab using RSUs (remote controls for the pushing locomotive).

I've already seen a joke that they're renaming the Harbourmaster Cafe to the Trainwreck Cafe.
