frankford, philadelphia. and brandon boyle represents parts of the philly area as well right nearby. congressman, you're the leader of the city politically, you are. what are you going to do about this? talk about this ptc thing? >> well, it's positive train control is a device that if it's in the engine and it's on the poles, it would have stopped the train. >> so it's a deadman switch? >> exactly. amtrak had it in the locomotive, but not on the pole. in 2008 we passed a law that all 100 railroads have to have this ptc in place by 2015. now the first i want to go back, i want to talk to the department of transportation. i want to ask for a public system-wide audit of where they're at, why don't these trains visit. it's supposed to be in hazmat trains and passenger trains. the delay you see today costs lives. and we can't get any more delay. they've got the money. >> you're going to make it law? >> it is law. they're dragging their feet. >> what's frustrating is we took a tour at ntsb and amtrak were nice enough and gracious enough
