I just read that the driver-less cars by Google and others have logged over a million miles driving themselves. I also looked up autopilot for airplanes and the article said that it is used in a lot of airports for landing especially in bad weather. The airplane autopilot has been around for quite a while now and is mandatory in commercial aircraft. So if cars and airplane have figured this out, why are not all trains fully auto piloted? How complicated can staying on a track and stopping were you need to be? OF all the transportation options this is the simplest to automate! Even if you are worried that some system might fail you can have someone sitting in the front with a button to push in case of an emergency. They can have sensors for obstacles and definitely control the speed. I don’t know why this was not done decades ago but now it needs to happen and those who use the trains daily for travel need to pressure the companies involved to make it happen now! It is just stupid that in this day and age we are having to ask why a train tragedy happened, and the only response is “I don’t know”!
