Trains crisscrossing Chester County will beat much of the nation to a federal government deadline to install automatic safeguards against potential crashes and derailments.

The Southeastern Pennsylvania Transportation Authority recently demonstrated the technology to elected officials on a Frazer test track. Both it and Amtrak say “using the most up-to-date safety technology is absolutely imperative” to prevent deadly derailments, reporter Matt Rivers said in a CBS3 report.

“It’s a non-negotiable top priority for those who represent constituents in the Northeast,” Chester County’s Rep. Ryan Costello said in the article.

The technology, called Positive Train Control, alerts and overrides train operators to keep them from speeding or running through stop signals. After a deadly Amtrak derailment in Philadelphia in May, SEPTA moved quickly to adopt the technology that, some say, could have prevented the tragedy.

Other transit agencies across the country, however, have struggled to garner the necessary funds to implement the technology.
