Never mind that, what about that train that disconnected its carriages whilst being en route to its destination earlier today? It left hundreds of people stranded on a bridge...

Hmm it is not as terrible as it looks, yes trains should never disconnect, but there was no danger whatsoever for anyone. The two linked EMU4 NID trains split, with both EMU4's comming to a automatic save stop.

It is as terrible as it looks. Yes, maybe there was no danger, but it still is already the third incident with a NID in service splitting unexpected (once the carriages of a set split, now on two occasions two coupled sets uncoupled unexpected). It never did that when it still was the DDAR. Something must have gone wrong during refurbishment.

It also happened before modernization, but it didn't happen often so people forgot about it, given that it made it to the news in the first place. The specific type of coupling used on the NID (BSI) is different from what is used on other NS operated rolling stock (Schaku), it's possible that a mistake was made during coupling which had gone unnoticed until the trains split en-route.

When two sets split there's no danger; when carriages are splitting the danger is very serious, there could be someone in the gangway.

I guess the DDAR/NID carriages are coupled with a traditional chain, so accidental uncoupling is much less probable than with Schaku.

Still, if it happens many times, something should be done... typically on the braking system.
We had a similar problem, basically one of the units was breaking late.

A passenger train lost its rear car on the Moerdijk bridge in Dordrecht on Monday, which uncoupled due to ‘unknown circumstances’, Dutch Rail (NS) announces. The automatic brake system kicked in immediately, and the 700 passengers were not in danger, a spokesperson said.
The new model double-decker train was on its way to Dordrecht, when the incident occurred at 7.30 a.m. The passengers were asked to wait in the train for half an hour before being evacuated.
It is unclear what made the train carriages become uncoupled. Due to the investigation from the Investigation Council for Safety, Inspection Living Environment and Transport and the NS, there were no trains on the Dordrecht – Lange Zwaluwe route. Other trains may also be inspected in the coming time.

Plus loads of footage in Dutch in several Dutch online newspapers...

NID/DD-AR sets are coupled with automatic BSI couplers.

Do they have electric and pneumatic connections as well, or is the hook just for rescue in case of breakdowns?

My bad, I was using "Schaku" as a generic term for automatic coupler

These are basically standard double deck carriages which are used in pre-assembled sets. To ease (un)coupling to other sets both ends of the train - either a driving trailer, mDDM or class 1700 locomotive - have an automatic coupler.

The hooks are intended for rescue and switching only, but I wouldn't be surprised there are electric connections hidden somewhere to. You can see the pneumatic connections just behind the buffers.

Congrats, something technical at the faculty of Applied Sciences in Delft? Or something else at the The Hague Campus?

Why should it offend specifically train operators?

Because nearly all of them have been confronted with mangled corpses having been struck by their train.

This is stupid. Have all train drivers suddenly decided to have a keukenhof outing? You might as well ban Die Hard for the same reason if they're that offended.

Do jumpers frequently wear bikinis? Is that the preferred outfit for suicidal people?

It is a well known fact that around 42% of jumpers wear bikinis. If you profess to not know this, you are merely showing off your own ignorance.

Naked lol. If I were a train driver and my windscreen had been repeatedly dick-slapped, I'd be a little annoyed too.
