Spanish train crash

Another sad day for rail travel, condolences go out to their families.

It's looking like overspeed caused the accident, the line enters a sharp curve there and the speed limit drops from about 125 to 50mph (85km/h) whilst a mile beyond the overspeed protection of the ETCS system (http://en.wikipedia.org/wiki/Europea...Control_System).
The driver apparently realised he was overspeed scant seconds before the curve, and well...the very harrowing CCTV footage below shows exactly what happened next:

Certainly at initial glance the fault potentially lies with the driver for not decreasing speed before the 50mph limit, however it's a very poor infrastructure design that puts a 500m radius curve that forces a sudden drop from 125 to 50mph. We have a similar problem at a place called Morpeth on the East Coast Main Line, and it's resulted in four accidents over 130 years, as trains have entered the 50mph limited section at speeds of 80 plus mph, although alcohol has, in a couple of the crashes, also been a factor.

Sheesh! :o I'd only heard about in on the radio and on the BBC News website, I didn't realise it was on CCTV.

If ETCS was enabled (and working) how could this happen?

Sadly the ETCS ended about a mile before the curve. :nope:

Doesn't it always boil down to human error?

My condolences to the victims.

In some shape or form, we design the system, make it and and maintain it, although sometimes things outside our control cause disasters, natural events, electrical faults, that kind of thing.

Best laid plans of mice and men and all that rot.:-?

Machines and technology cannot eliminate the factor of human error. What I'm wondering is, if the ETCS ended before the bend why isn't there a part of the line to reduce speed a certain distance before reaching the bend? If the speed on the straight is 125, then a reduction in speed to around 70 or 65mph before the turn should be called for which would make it much easier and safer to enter the turn at 50. Trains don't stop on a dime, let alone slow down on a whim.

I agree....an extra safeguard before the bend may have prevented this disaster....something to override human error.

The link actually shows the train taking the bend at high speed and well you know what happened next............

A railroad car, being lighter, and having a higher center of gravity, than the engine, it is not surprising it was the first to derail. What a horrible accident.

When I posted this link, I thought it was a tragic event. Turns out that my wife's cousin's girlfriend's Spanish housemate's best friend was on that particular train and one of the fatalities. It is a small world. It made for a quieter evening with everyone around our house last night contemplating life.

Live each day as though it were your last.

I don't pity the dead. I pity the living.

An interesting and thought provoking blog post about the aftermath of the crash and some questions that need to be asked of the Spanish railway company. I have, since the crash occurred, been concerned that too much focus would be placed on scape-goating the driver and not enough on the infrastructure in which the crash occurred.

EDIT: And for those who are interested in this sort of thing, earlier on this thread I mentioned a place in the UK called Morpeth and the various crashes that have taken place there over the years. One of which took place in 1969 and resulted in the following investigation and report:
