“Positive train control” system is required by federal law to be installed on all passenger and major freight railroads by the end of 2015.

If that had been done already, this crash would more than likely not have happened.

Amtrak says it will be done before the deadline.

True. I also don’t get why that can’t be implemented fairly cheaply via GPS. At the very least an audible alarm could be sounded saying “Hey motherfucker, you’re going too fast.”
