A computer-controlled area-specific speed-limiter device should do the trick.
Or, at the very least, a device that knows the max-speed based on your GPS
location, and that makes an alarm sound if you're above the speed
you're supposed to be. Also, the operator should be held liable for all
the times the alarm goes off on their watch!
@JBQ - the operator may well have acted correctly - only the final investigation
"may" lend some insight. You may want to check the statement that the
"conductor tried to apply the brakes" - a second person - and the brakes
did not respond - this would be an interesting point for me. Finally - trains
use air brakes - which require pressure to keep the brakes away from the wheels
- so that if an air line is ruptured - the brake will be applied - more of a
fail safe approach.
One of the New York papers quoted an engineer who looked at the photos and said
that he knew right away that the train exceeded the 30 mph on the curve. The
next question would be why? If this be true, then why didn't the operator
do his duty? Was it negligence or what was it a controlled substance or even a
