>There was a car on that train that was on fire for at least 20 miles before the derailment. If I can get pulled over for having a busted tail light, a train full of toxic chemicals should get stopped for being on fire. Unfortunately, a wheel/bearing running hot for ~20 miles could be well inside the usual spacing for defect detector stations[1] in the US. Can't speak for this specific rail line but they're often as far as 30 miles apart, and not every detector will have the sensor package to identify wheel/bearing issues (though most will). If you ever ride Amtrak, you'll occasionally hear trackside detector units radio in a diagnostic report over the conductors' radios. They have automated voice systems that announce their position, sensor reading states, etc. [1]https://en.wikipedia.org/wiki/Defect_detector https://en.wikipedia.org/wiki/Defect_detector
