Purple rain this is the cbs weekend news. Quijano good evening, im Elaine Quijano. For the third time in less than two months federal investigators are at the scene of a deadly crash involving an amtrak train. The latest wreck happened early this morning in cayse, South Carolina, across the river from the state capitol, columbia. A passenger train believed to be on the wrong track plowed into a Freight Train killing at least two people and injuring more than 100. Kris van cleave has the latest. Reporter early indications are amtrak train 91 was traveling at about 59 Miles Per Hour when it hit a c. S. X. Freight train around 2 30 sunday morning near columbia, South Carolina. On board the new york to miami train, were nearly 150 passengers and crew. The 54 yearold engineer Michael Kempf of savannah, gerogia and 36 yearold conductor, mike cella of orange park, florida were both killed when the lead locomotive and several of the passenger cars derailed. Think of the worst car wreck youve ever been in. Thats what it sounded like. Reporter derrick pettaway was sleeping on board when the accident happened. I wasnt able to embrace myself properly. I ended up going into the wall and kind of gave myself a bump on the head, nothing too major. Margaret fisher is a lexington county coroner. We shouldve had a lot more casualties but we didnt. Reporter 116 people were taken to the area hospitals with a range of injuries. The National Transportation safety board is now on scene and investigating the crash, as well as switch equipment that may have put the amtrak train on the wrong track. Chairman robert sumwalt. The key to this investigation is learning why that switch was lined that way. Reporter South CarolinaGovernor Henry Mcmaster toured the crash site. The first engine of the Freight Train, of course, was torn up and the single engine of the passenger train, the amtrak train, which was headed south was barely recognizable. It is quite a quite a crash. Reporter investigators are still on scene, they have been able to get their hands on the amtrak trains forwardfacing video camera, that video is being sent to washington. The train right there, you can see the force of this collision completely knocked some of the passenger cars off the tracks. This is the third fatal amtrak accident the n. T. S. B. Has begun investigating since december, elaine . Quijano kris van cleave, thanks. For more on this we turn to former n. T. S. B. Chairman and cbs news Transportation Safety analyst mark rosenker. Mark, this is the third amtrak related accident in two months. Does the company have a safety problem . Absolutely, elaine. Three accidents in 60 days, this is absolutely unacceptable. And things need to change. This is Americas National railroad. Passengers are entitled to clean, efficient, safe transportation. Quijano well, you were chairman of the n. T. S. B. In 2008 when positive Train Control Technology was mandated. The safety feature can help stop a train before an accident. Why has there been such a delay in getting this installed . This has been one of the great disappointments to me because i thought we had solved this problem with the Railroad Safety improvement act of 2008, requiring class one railroads to install positive train control by the end of 2015. That was seven years of possibilities of getting this technology put into affect. They only had the class one railroads about less than 20 of the tracks complete by the time that deadline occurred. So the railroads went to congress and said that theyre not going to be able to operate unless they get an extension. The congress caved in, gave them that extension and people died as a result of that over the past year or two. Quijano all right, mark rosenker, thanks very much mark for your time.
