No apology necessary, good sir.
The problem with information of that nature, beside its being proprietary, is the media 'reporters' who don't know the differrence between 'investigate' and 'repeat verbatem', nor do they recognize the difference between 'truth' and 'sensationalism'. Most folks don't know what a drawbar is or does on the railroad, much less what PTC is, nor where or why or how it's used. Even the big Class 1 roads had to ask for waivers, due to the sheer magnitude of the undertaking. All new equipment purchased, or rail lines upgraded, have had PTC as part of them for the last several years. It's mandated. Every little device has to have a radio link for communication with the system. I mean, even a burnt-out lightbulb at a public crossing at grade is tracked, and restricts trains. The complexity of the system is immense. The cost is immense. All of the privately held railroads, big & small, have been working toward compliance with the beast of a system. The entity that is lagging (that I know of)? Federally funded Amtrak. Why? Probably budget... They are trying to do a lot with the budget they have, but still... Railroading is not a low-cost, high profit industry.
