quinn, mister leahy. >> thank you. good afternoon chairman collins and ranking member reed. thank you for having us here today to comment on rail safety. metrolink is the first railroad in the nation to have operating ptc on all of our host territories. metrolink is a network connecting six counties across seven lines that traverses more than 500 miles of track. i should note we operate on the corridor out west, which is the second busiest amtrak corridor in the country after the northeast corridor. our freeways in southern california are at capacity. our operation is still growing and spreading out. the only way to relieve traffic and congestion is getting cars off the freeway and metrolink does that. our folks take the train to work, rather than driving. we have done a number of things that metrolink over the past few years, because of our goal to have improved safety. rear facing cameras for example and crash management cars were implemented years ago. our journey into ptc was triggered by a tragedy in 2008. 25 people lost their lives and many more were injured when there
