Really , it should have been done decades ago. if you count up the costs of avoidable accidents over the last 20 years , I think it would surpass the cost of installing PTC. Plus you'd have 110 mph or better trains in a lot more places. And potenially closer spacing/ faster running of freight trains.I guess it depends on how one defines "high tech." From what I've seen first hand in the development of these systems on a specific (large) Western Class I railroad, I would have to respectfully disagree. The level of complexity, as currently being developed and implemented, far surpasses any legacy systems already in general use, and the technology has not been available for "decades."
Industry analysis has shown that PTC does not make sense in purely financial terms (as compared to what so-called preventable accidents have cost historically). It's generally seen as an overkill solution that will tend to slow the operation down significantly, without sufficient payback to support the investment of private funds.
But aside from that, of course, the prevention of potential fatalities is not so easily dismissed.
We don't know what we don't know.
