>> in twrai a 2008, a train derailment killedrailmentoutside los angeles killed 28 people. think of positive control as sort of an air traffic control system that can take control of trains. positive control would add gps satellites sensors on the tracks and a centralized system that can slow or stop a train when it senses trouble ahead. it would have stopped the train from exceeding the speed limb. >> we have advocated positive train control. it is one of our wanted list. >> it makes the human driver to make an adjustment if there's a double parked car or a dog dog in the street. but once these trains go below ground, it can monitor the drivers make sure they're not
