Transcript for NTSB Vice Chairwoman on NJ Train Crash Investigation
People want answers. Moments ago, I spoke with Bella dinh-zarr. The vice chairman of the ntsb. This is our first full day on scene. We arrived as soon as possible yesterday. Afternoon. And, we have found that this is a -- push/pull car configuration that has crashed into this hoboken station. We're in the process of securing -- making sure that the site is safe so our investigators can access all of the information that's available on these three cars as well as the engine. So, right now you have had limited access to the accident site? That's right. We did have access, however, to the locomotive. We are able -- we were able last night to take out the recorder. We'll get information from that event recorder. You want to talk to the engineer and others, right? That's right. We'll interview the engineer. We have made that request, as well as the other crew members. We'll check records. Maintenance records, employee records. We'll do all the usual standard operation review of the records. What are the main questions you'll be asking the engineer? We'll be asking the engineer what -- exactly what he was doing. We always look at the 72 hours before the accident to make sure that, you know, to follow his -- his activities during those periods. We'll be asking what he remembers of the actual crash itself. The New Jersey transit rail was ordered to install a safety system known as positive train control. Ptc. This was back in 2008. Can you describe what this does and could it have prevented this accident? Well, the ntsb, robin, has been recommending positive train control for more than 40 years now. It's a safety system that prevents train-to-train crashes and also prevents overspeed crashes. By preventing derailments. That type of system, could it have prevented this accident? That's what we'll be looking into. I know everyone is really anxious for information. And as are we. We want to look very carefully and be very careful before we present anything other than what we find in our investigation. That's fully understood. Everyone is anxious for the answers. Thank you very much for your time this morning. I know it's a busy day ahead. Thank you. Bella dinh-zarr. Hopefully, the engineer and other crew members can provide answers. Hopefully in helps push that system forward. Now that massive hurricane Matthew gaining strength
