Dutch train derails at Dalfsen

More information

 

The train hit a crane on a crossing, tilted over and went into a field, leaving several carriages lying on their sides.

 

 

Not a derailment but a collision with a vehicle which then caused the derailment. One dead but things are fluid at the moment.

Dutch report with pictures at De Telegraaf here: http://www.telegraaf.nl/binnenland/25250411/__Ongeluk_met_passagierstrein__.html

 

As far as I can tell, the driver was killed ("De machinist is bij het ongeluk om het leven gekomen"), and 10 people injured. At least one carriage completely on its side.

Road vehicle was a tracked boom handler/crane type thing ("Een hoogwerker op zogeheten rupsbanden").

I can confirm that the driver was killed, of the ca 15 passengers 7 where injured, 2 of which have been hospitalised. The entire train is on its side, it's a Stadler GTW 2/8 type by "private" TOC Arriva*. The driver of the tracked vehicle is being questioned, but apparently he made an error of judgement: he waited to cross the railway until a train in the opposite direction had passed, but while crossing the line, the accident train came the other way. Dalfsen has a passing loop, being on a single track line. It's safe to assume the road vehicle driver was unaware of this.

 

*Arriva is everything but private, being wholly owned by DBAG :rolleyes:  That's OK, NS owns Abellio, which has a substantial presence in the German regional train market ;)

 

I'd just read a similar report on a Facebook group. I posted the question as to whether or not the crossing had lights and barriers.

One thing that I am puzzled about is that the cherry-picker (?) Waited for one train to pass. Now, whilst not the fastest vehicle in the world, if the cherry-picker began to cross after the train how did it take so long that the train arrived at the station to allow another into the section and then be able to reach the crash site?

 

Something more to this I think.

The protecting signals are next to the station building, so a little further in from the end of the loop - I made it 4.5km from there, or a 9km "round trip" - I'd just done some sums in another place based on an assumption it was 100kph running (which might not be correct) - that would give 5.39 minutes of running time at full speed from the crossing to the station and back, that's not counting braking and accelerating, so over 6 minutes is realistic.

Even at 1kph though (about a quarter of walking pace) you'd still cover over 16.6m in one minute, I suspect the vehicle should have been capable of that speed - if so, he should still have had 5 minutes in hand...

My understanding is it was not a cherry picker but one of these. >> http://rocketrentals.co.uk/images/Upload/Telehandlers/THL_540-170_02S1.jpg

If as shown above the train approached from the right the telehandler drivers view of the train would have been obscured.

The first photo link has a single photo shewing what apppears to be the tracks of some sort of vehicle with a 360º rotatable top on it (the 'turret' mounting for the top is visible).

If it was a telehandler the problem with them is if the the boom is raised at a certain distance it can dramatically reduce your right hand vision. If the road crossing was not level the boom would have to be raised higher than normal for road use (where you can normally see over the top of the boom) to stop the bucket grounding, but you cant raise high enough to see under the boom if the track has overhead wires.

This give you a better picture of the visibility from our one. The newer ones are a bit better for visibility.

The article linked by Dutch_Master in post 11 says it was tracked (rupsbanden), and had a max speed of a couple of km/h, which suggests it wasn't a telehandler

 

De hoogwerker had rupsbanden en kan maximaal een paar kilometer per uur rijden.

If you do a google image search on "hoogwerker" you get cherry-pickers and other aerial platforms.

There are tracked nascelles/ cherry-pickers; often used for catenary work, amongst other things.

Looking at more images, definitely looks to be a tracked cherry picker and not a telehandler. If you dig through the images you can find in distinguishable "lumps" the tracks, the "turret", and a boom still with cherry picker basket on the end.

Interestingly the boom looks to be almost fully extended, if it was like that before the impact it might have made handling it harder maybe, especially getting it under the catenary?

Company name (presumably who it was hired from) on the boom is van den Brink - which I think is these folks: www.brinkkraanverhur.nl - they have a large range of different "Hoogwerkers" - many of them tracked.

The link doesn't work, it might need a / on the end.

I believe this type is called a cherry-picker in English. Whatever the name, these are banned on public roads (and railway crossings are classified as such), unless to actually do work. The train hit it at the rear and dragged it along for about 100m. It appears, assuming the reconstruction is correct, that the frame then hit the concrete base of an overhead mast, which then acted as a pivot/anchor which then threw the front bogie off the track, after which the rest of the train followed and capsized. Speed: 100kph/60mph. Investigations have begun and it's safe to assume not only the cherry-picker driver will have to answer some tough questions, so will Stadler!

Why will Stadler have questions to answer? Yes the cab was destroyed, the same would have happened with most types of multiple unit, and the overturning is a result of the train being articulated, like many others across the world.
