Has anyone ever thought of adding say a light beam or something to indicate if the railway is blocked so that an oncoming train has time to stop?

That woman was lucky, extremely so, I did not think the train would be able to stop in time. Were I the conductor of that train and I did everything possible to stop the train i still do not think I could watch it. I'd have to turn away, or close my eyes.

Did you consider this before suggesting it?

Where would the light beam go? Perpendicular to the tracks? How far apart do you make them?

Parallel to the tracks? What if some jerk throws garbage down there?

Perpendicular wouldn't work, it wouldn't cover enough area. A cross beam at an angle could increase coverage.

I can think of a few different ways to plan it. Perfect solution? No, there are problems with each methods I thought of. There are even problems with using object detection like the camera system they have in place.

I'm not saying its THE solution. Just a possible solution with some work.

Whats with the expletive? You know its going to get blocked by the filters.

Like a lot of things, its going to be cold-blooded cost analysis that makes the decision. I would suspect that the amount of people who fall in front of the trains is so low that it would not be "worth" the cost of implementing an effective system.

The people making the decision almost never state it so bluntly, but the principal is in affect all around us.

The entire last sentence was iPhone-ized, I am sure you understand. My apologies. It is now corrected above.

Essentially, (as you stated) the false positives would be enumerable.

IR sensor checking the tracks' area. It it's not warm and a reasonable size, it wouldn't trigger.

Why not just use the existing frontal camera, which clearly has body recognition? Notice the red rectangles following that man (a true hero, risking his own life) and woman?

The frontal camera clearly recognized someone on the tracks (red squares). That should have turned on the red light to the incoming train.

Was that lady like drunk or high or something? She seemed seriously out of it....

They really should put some kind of railing or plexiglass system along those subways. We don't have a subway here in my city but I'm pretty damn sure if we did we would have some kind of railing system along the edge to prevent stupid people from falling.

Yes we have alot of stupid people here so it would be built with them in mind.

It would probably be difficult to implement a system like that and not have it keep being triggered erroneously.

Why would the conductor have to stop the train? That's the driver's job.

They have such a system on the Jubilee Line extension on the London Underground. All the new stations' platforms have a glass wall with doors that only open when there is a train stopped there.

The problem is, I think the NY system is probably one of the largest (if not the largest) in the world. The cost of retrofitting all of those stations as you describe would be enormous, and in real life I can't imagine who would sign off on that expenditure.

I found it ironic that the only person who got hit by the train wasn't the one on the tracks.
