Nvidia worker killed by Caltrain was trying to save man on tracks

For a man to risk his life -- and to lose his life -- for another, perhaps even a stranger, is something else.

I once was caught in the path of an oncoming train. I was on a school bus when the driver attempted to cross the tracks before the train. The bus stalled mid-way. My seat on the bus was directly over the tracks.

The train came around a bend and all the kids panicked. Half went to the front door, jamming it, and the other half went to the back door, jamming it. I was trapped. All I could do was watch the train coming and pray.

The engine suddenly started back up and the bus started to move as the train was getting closer. The train missed us by a couple of feet.

I know what this man saw coming toward him. You don't ever want to see one of those things coming at you!

To control that fear as you're trying to help another... this man was a hero.

It's 2014. Why don't tracks have sensors communicating with trains over radio waves?
