Install TCAS on all trainies?
Train crash avoidance system?
Kidding aside, I think the fact we've been implmenting PTC for decades now and it's still not done shows how much the railroads and our country care about this...
3BS is trying to be mostly serious...Aside from some outstanding 'subways' and shuttles between closely-situated megalopoli, Rail travel is a near total disaster of a business model...
"For the same price as Flyboy and Dummy, we can get you there
much more slowly"
...(sure the seat pitch beats the hell out of airlines, and the scenery is generally better on cloudy days, and you don't have to worry about takeoff flap configurations, nor relentless pull ups...just that someone has the switch set right and the driver isn't confused about the speed limit, and trust that they do the proper brake-test procedure during the crew change)
AND THEN, the whole thing operates in the red, with significant government subsidies...that are shrinking regardless of whether Savior Barak or Savior Donald are in charge...so when you need new engines and new cars and union crews and faster tracks and rent from a private RR while you mess up their 30 MPH freight trains...the electronic wizardry lags behind a bit.
Plus, even with PTC, I think more crashes are idiot cowboy car and truck drivers at grade crossings...Yeah, there's plenty of $ to convert all grade crossings to some sort of bridge...
