There have been a number of highly-publicized accidents on America’s railroads recently. Yet, according to a 2017 data from the Federal Railroad Administration released by the Association of American Railroads, the train accident rate, equipment caused accidents, track caused accidents and derailment rates are all down substantially over a fifteen-year period. So what are we, the passengers, to think? On this episode Dr. Joshua Estrin, a forensic safety specialist, joins us to consider whether our railroad system is imbued with a culture of safety and whether truth may fall outside of the numbers. One thing is for sure there are many players in the railroad industry–some private, some public, not least of all the Congress–which make an assessment of the situation difficult. We examine the case of positive train control and what it holds in store for safety going forward. And ask why it’s taking so long.
