"Details of Philadelphia's train crash investigation remind us how much we do not yet know. Investigators do know the train was moving too fast into a curve. Video shows the train accelerating into that curve. It is still not clear why, though. Also this week, many Americans learned of technology that can prevent a train from going too fast. The president of Amtrak now says that safety system was installed in the area where Amtrak train 188 sped off the tracks. It wasn't switched on yet. Testing was still needed to make sure the technology was working. NPR's Nathan Rott reports."



"ROBERT SUMWALT: Sixty-five seconds before the end of the recording, the train's speed went above 70 miles per hour.

ROTT: Twenty-two seconds later, it was going above 80.

(SOUNDBITE OF ARCHIVED RECORDING)

SUMWALT: Sixteen seconds before the end of the recording, the train's speed was going through 100 miles per hour."



so yes they do have something, no it wasnt implemented yet. the train started accelerating for a grand total 65 seconds, i dont think thats alot of time for someone to verbally warn a conductor over a radio or something
