Submission + - Feds order Amtrak to turn on system that would've prevented crash that killed 8 (trains.com)
In response, the Federal Railroad Administration (FRA) is issuing formal emergency orders that will require Amtrak to make sure automatic train control systems work *NORTHBOUND* through Philadelphia at and near the site of the derailment. The FRA is also requiring that Amtrak assess the risk of all curves along the NEC and increase the amount and frequency of speed limit signs along the railroad.

FRA's emergency order is newsworthy because Amtrak's existing signal system could have been configured to prevent a train from exceeding speed limits, according to the Wall Street Journal (http://www.wsj.com/articles/amtrak-crash-might-have-been-avoided-by-tweak-to-signal-system-1431622980). The newspaper reports that people familiar with Amtrak’s signal system said speed-control measures used elsewhere by the railroad could have prevented Tuesday’s crash. Amtrak officials said they were concerned enough about the curve to install the added protection on the two *SOUTHBOUND* tracks. But it wasn’t installed on the *NORTHBOUND* side because officials didn’t believe the tracks leading to the curve would allow trains to build up enough speed to topple over.
“It would have prevented the accident if it was operational,” National Transportation Safety Board member Robert Sumwalt said Thursday in an interview.
Interestingly, Amtrak President and Chief Executive Officer Joseph H. Boardman was head of the FRA before taking the reins at Amtrak. (http://www.amtrak.com/servlet/ContentServer?c=Page&pagename=am%2FLayout&cid=1251623383973)
