That this is a problem is just ridiculous. It's on freaking rails! There is absolutely no excuse for this. GPS, Inertial Nav, simply integrating speed over time, it should be absolutely dead simple to calculate exactly where the train is at all times.
The article mentioned crap like differential GPS. Completely unnecessary. You don't need to be that accurate, I mean good grief, +/- 100 feet would be just fine for dealing with such gross overspeed detection.
I can't believe this is actually a problem. Pure politics/bureaucracy. It's certainly not a technical problem.
