  • Most US rail operators won't meet deadline for train safety controls

    According to a US Government Accountability Office (GAO) report, as many as 70 percent of rail operators won't meet the end of the year deadline for safety controls. Operators are legally required to install positive train control (PTC) systems that slow trains traveling too fast (based on location) by the end of the year. The GAO says that only five rail companies will meet the December 31st deadline to have the safety tech in place. An automatic train control (ATC) system was only installed in one direction on the section of track where an Amtrak train derailed near Philadelphia earlier this year. As you might expect, the safety feature may have prevented that accident entirely by automatically adjusting the train's speed for that portion of the route.

  • Amtrak installs automatic train controls before service resumes

    Following the deadly accident last week near Philadelphia, Amtrak installed a braking system on the section of track that could've prevented the derailment. The automatic train control system (ATC) keeps tabs on a train's speed as it heads toward curves, automatically adjusting it if the conductor fails to do so. ATC was already used for southbound trains in this spot, but not for those headed northbound like the one that derailed last Tuesday. In addition to the ATC, Amtrak is working to equip trains with a Positive Train Control system (PTC) which uses the ATC to further automate trains while avoiding collisions, maintaining safe speeds and providing safer conditions for work crews. Amtrak plans to have the PTC in place by the end of the year. The Federal Rail Administration announced today that Amtrak had completed all of its requirements to resume service along the Northeast Corridor between Washington, DC and Boston, and that the train company would continue to evaluate other curves along the route.
