It was in Spain, Santiago de Compostela.
There are special sensors that help, but at the end it all depends on the "pilot"...
A GPS assisted and a beacon system should be easy and not so much expensive to implement, and at least it would avoid this kind of problems.

What I don't understand is why someone that has a job, where there are 2 things to do, use the accelerator and the brake is incapable of doing his job. The guy doesn't even need to steer it.

It seems he may have fallen asleep on the job. He admitted to being sleepy in radio communications earlier in the trip. That leads to the question of if he did a stupid and didn't get enough sleep on his normal schedule, or was a last minute replacement and normally worked a shift where he'd've been sleeping when the accident occurred.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I think a dead man switch wouldbe enough to counter this. Operator falls asleep -> train stops. Simple as that. Ok, probably there should be some additional system to prevent the next train from crashing into the standing one.
The good thing about pessimism is, that you are always either right or pleasently surprised.

The less you have to do to concentrate on the task at hand, the more likely you are to drift off to another dimension.
I know that when I am stuck in a long line of traffic cruising along at some rediculously low speed I'm ready to fall alseep after 10 minutes, but if I drive (or better yet, ride the motorcycle) fast (ie over the speed limit, the more the better) my concentration level is way better because you have to react to more things in a lessor time frame.

Or have you never had a bug?

The job of a footballer is to kick footballs into goals. Their entire working life (at least 8 hours a day) is dedicated to learning how to do this and practice doing it.
How many miss penalties?

There is, Singapore's MRT has no drivers on most (if not all) of their rail. Arrival times are every 1-2 minutes in peak times and the operators get fined $1m if they cause a major delay. They have an excellent ticketing system that causes minimal delays and a trip of 6 stops cost 86 CENTS in off peak and something just over a $1 in peak hour.

Because they like to go really slowly while they check tickets, then speed up.
That would be tricky to automate! I'm not kidding!

Turns out it's on it's way. Mandated in the US by 2015 for passenger trains.

Genghis Kahn, being in a good mood decides to spare one life of his 1,000 captives. He has them stand in a circle and runs a sword through every second man.
If the first man is #1 [amongst Kahn's many crimes was a love for VB], which man will be left alive?

Well, unless Genghis Kahn decides to stand in the circle, he should be fine.

The last one standing.

9,41,73,
9,73
73
73 survives!

You're in the right area [not]. If it was 100, then 73 would survive but there were 1,000.
[clue]
For smaller cases:
Prisoners 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
Survivor 1 1 3 1 3 5 7 1 3 5 7 9 11 13 15 1 3 5 7 9
There is a formula here...

Are you sure your clue is right? For example, with 14 prisoners, how can #15 be the survivor?

Brain's not working properly today - I can see the pattern, but I can't see the formula. Is the answer #977?

Well done!
For the number of prisoners P find N, the highest power of 2 less than or equal to P. The survivor S, is:
S = (P-N) * 2 + 1
