Staggering video of terrible train crash in Croatia

I had read about the incident in Todays Railways Europe, but didn't realise it had been captured on film. Truly terrifying.

Blimey what speed was that works wagon going at & a few second previously people were walking on the rails.

Presumably the truck was on its way to rescue the derailed train, and misinterpreted the site of the derailment. It happens. Not that many years ago, a train failed on the Down line between Paddock Wood and Ashford. A Class 47 was sent in to assist, completely failed to recognise the site of the failure - and ran into the back of it. A "clear understanding" between/among participants is a basic requirement of operation when things have gone wrong.

You would have thought it would have proceeded with caution.

This was a nasty accident.

 

I believe the primary cause was p-way staff treating the wooden sleepers with some type of flame retardant (to prevent combustion in the excessive heat of a Croatian summer) , this caused contamination of the railhead , which meant that the tilting 6122 DMU (which run at higher speeds) was unable to slow down and derailed - this same railhead contamination is what caused the trolley to slide as it did.

 

Sadly modern disc braked trains are unable to properly cope with contaminated/wet/slippy rails , even with wheel slide protection (think of ABS on a car).

Correct. Vide the collison at Richmond when a London Transport D78 slid into the buffers after PW staff had cleaned the old grease out of the points with a stick - and wiped the stick on the railhead. No brake shoes to wipe/burn the residue off the treads means it's there until something else stops you....

i'd heard of this as an issue with either the 156 or 158s - disc braked, but later fitted with conventional blocks to clear the treads for grip/track circuiting reasons. thought it was a new thing, but it was known about at the time of the introduction of the HST - power cars had girling disc brakes, but were fitted with 'conventional' shoes, only not for braking

go to page 12/20 for 'brake equipment'

 

it states that these blocks also functioned as the parking brake

The maintenance vehicle is clearly running away out of control; it's not clear whether or not it's still on the tracks when it passes the cameraman, but look at the way it's swaying about.

 

Did it actually hit the derailed DMU? The cloud of dust means you can't tell, but it doesn't really look like it did.

I wonder what they do to the ties to begin with. We operate railroads with wooden ties through hundreds of miles of desert with hotter, drier weather for longer periods and don't have to treat the ties to prevent combustion.

Like they say WSP is designed to make maximum use of available adhesion. If you have zero adhesion, your'e stuffed. I went to Croxley Green one Monday morning when a 313 on dew-covered rails with Sunday's rust film ran into the bufferstops.

Should really have multiquoted this with the above. There was also a case on the Dundee to Perth line where the rescue loco ran into the failed train and tipped some of the coaches into the Tay.

That wasn't the rescue loco - it was the following train (a Glasgow-Aberdeen express) which overran signals. Several fatalities, including the driver of the second train.

IIRC the brakes on the class 25 hauling the passenger service were stuck on and overheated. I think the guard was running back along the track to place detonators when a class 47 approached at a rate of knots and ran into the back of the failed train, hurling a couple of coaches over the sea wall into the sea, and destroying the class 47.
