Whole story here of whats left behind, this twisted mass of metal, glass, luggage. 243 people on board. Some just tossed around. You heard one woman was found hanging upside down. Others were crushed as the carriages tipped over. One passenger says he watched as women were launched into luggage racks. Another sat helpless as people were crushed under a row of seats. Most of the passengers were rushed to hospitals, some are still unaccounted for. We heard the mayor saying that the search operation there on site continues. We also know the number of those who lost their lives is now at seven. Cell phone video showing what it took to escape that mangled train. Watch. Here hold on. Hold on. Go go go. Should i just get out . Hold on. Help me. So many people jumped into action if they could, helping others. Prying open these doors. Others crawled through all this jagged metal. Come on man. I got you, okay . Keep crawling okay . Where am i crawling to . Crawl forward, sir. Keep crawling. We just heard from the mayor of philadelphia Michael Nutter who spoke just a short time ago. You know last night when we first arrived on the scene, we knew it was bad. Lighting was not particularly good the first time we went there, but you could see just the devastation of a train. I ride the train on a regular basis. Ive been on the 710 out of washington, d. C. Coming back to philadelphia. Ive used amtrak a lot. But to see these cars these huge metal vehicles turned upside down one basically almost split in half most of the cars either upside down on their side or tilting, the engine completely separated, you know this is a devastating situation. But that was last night. And then the second visit when we had more light, wed brought in light cannons, but to see it in the daytime is almost indescribable. It is painful. And it is amazing. It is incredible that so many people walked away from that scene last night. I saw people on the street behind us walking off of that train. And i dont know how that happened but for the grace of god. Lets go straight to the scene, to my colleague ashleigh banfield. Were watching and waiting for that News Conference from folks at temple hospital. Meantime speed. We know they have the event recorders, these black boxes, a lot of data theyll be able to green from that including exact exactlyexact exactly how fast this train was going. Yeah. There at the headquarters they have that data. They should know some pretty salient information about rene marshs sources. Cnn reporting that sources close to that investigation say that train was going in excess of 100 Miles Per Hour as it approached to that curve. Ive seen that curve. Ive seen the devastation that lies after that curve. That curve is rated for 50 miles an hour and for good reason. It is a sharp curve. It brings to mind the incident in the bronx in which a train derailed going 80plus miles an hour in a 30 zone. Several People Killed there as well in 2013. So as we continue to wait on further details of the investigation, mayor nutters News Conference yielded a lot more new information. A lot of this is preliminary, but there was a lot of information. First and foremost two United States congressmen were here on location. They not only toured that scene of devastation, but they were also briefed on the information that perhaps isnt all necessarily public yet. We also know there are seven dead now. Thats up one from the count when we got the official release back at 10 00 a. M. They also said that they have started notifying next of kin. Thats critical as well. They said the data points of reconciliation include hospitals, ems transport. So they brought that into the mix as well trying to figure out, who did you take who did you get to the hospital where did you take them, what are their names . Friends and Relatives Center trying to coordinate those people whether they still have someone missing. Also the medical examiners office. That detail and those pieces of data coming in for that reconciliation of data points to figure out if theyre still missing anyone. The mayor, brooke said that they will go through every single vehicle until they find out whether theyve left anyone behind. They also said canine dogs involved in this and that they have expanded the search area. The mayor got real specific about that too, saying that it is entirely possible that someone may have been thrown from this train during this wreck. So the canine dogs hard at work. We cant get anywhere near this location at this point. The location i went to was sort of a high point atop of a building in which i could look over this rail. I couldnt see any visible scarring before the bend. I couldnt see anything that would have indicated that train derailed anywhere before the bend. Naked eye only. Again, im a layperson. But it certainly looked as though the derailment and damage came to the midportion of the bend or afterwards. Also want to make a huge correction that the mayor himself had to correct. He reported to us at 10 00 that it was the conductor who was injured and treated and released and debriefed by the police here in this city. Hes now corrected that to the engineer. Thats a big difference. The conductor does ticketing. Youve seen the conductor going up and down the aisles of the train. The engineer is the one whos operating the train. So whatever data that this engineer is able to download to the police and to investigators will be massively significant in all of this brooke. Absolutely. As you mentioned, that event recorder sitting in wilmington, delaware going through that piece by piece, figuring out the what the why. Ashlee thank you. Let me bring in cnns safety analyst. I want to hit home this point of speed. I was talking to someone who knows training very well. What i didnt realize is theres a train control system in place. If a train is going too fast there is a warning system. So either the engineer can slow the train down manually or it should automatically slow. Is that correct . Yes, it is. And both of those things should have been in place with this train and probably were. Thats why investigators will be looking very closely at whether or not that system itself was functioning normally. Had it been normal it wouldve given the warning first. If its excessive speed now that, doesnt necessarily mean its just a little bit above what the recommended speed is. It would have waited until it was high enough to risk a derailment. Then at that point, it would automatically deploy the brakes. That system has been under some investigation and some questioning, as would any kind of auto takeover system of any kind of train or airplane or car because it takes some knowledge and takes some really intricate maintenance to make sure its performing the right way at the right time because putting the brakes on at the wrong time can throw the whole schedule off for trains and cause other problems as well. So put yourself in the shoes of these investigators. Obviously we know the engineer the one who drives the train, hes given a statement to investigators. We know ntsb is on the scene. They have to meet looking at the tracks how the cars are now laid flat or mangled in some situations. What exactly i guess all of the above theyre really looking into. Really the first thing is going to focus on the engineer. The engineer will probably undergo toxicology tests just to make sure he was, you know, very aware, that there wasnt and im not suggesting there was. Its just a matter of routine. Its what you do in any kind of accident. You want noto make sure that engineer is tested and his blood alcohol is where it should be. Ruling that out, the next thing you look at by the way the train is twisted, you notice the first car, the engine itself is not nearly as mangled. That doesnt necessarily mean the cars behind it derailed and it didnt. It means that engine is much heavier and a greater mass than any of the other following cars. So the inertia from the cars behind come forward and actually mangle. You notice that second car is very twisted and mangled. That would make sense in a derailment. As it rolls over the cars behind continue to force all of that energy Going Forward into that car. Thats one of the things youll look at there, a clue as to whether it was a derailment from a highspeed roll or whether it was a derailment from something on the track or the tracks actual narrowing. Amtrak has been very good about that. They have very extensive systems in place to ensure that the tracks are at the right parallel theyre the right angles for the turns. I dont expect sptsuspect that but it is something theyll be looking at. Is it time we have seat belts on trains . Who would that have helped . I think i think it would have. Back in 2007 there were three studies done. All three said that well each one had a different focus, but one of them was talking about a threepoint harness, whether its worth it. They said no, its not. You have to question was that the right question to ask . Should it have just been a lap belt maybe thats something they should have looked at more in depth. Ive read all these of three reports. The other thing about these reports is they were really focused on whether or not someone would be ejected from the train. You mentioned earlier theres dogs out sniffing looking for possible people that have been ejected from the train. Now, the strength of the window glass has been something thats brought into question there. If you strengthen the window glass to keep people from exiting the train, then you risk the make an inability to get out. As with any safety feature, it can also cause vulnerabilities. Thats one of the things they looked at in this as well. The idea that the seat belts are needed or not needed is really kind of ruled out by the fact the inertia of the train is much different than youd have in a car or a small van or maybe an airplane in that the inertia of the train continues to go forward and really kind of plow its way through things. You wouldnt get those abrupt stops you would expect in smaller vehicles. But in this case you can see clearly this had an abrupt stop. Clearly there were bodies flying through the air, debris flying through the air. This was something that was not looked at in any of those three studies, whether or not a person not attached would cause injury to another person on board the vehicle, which is i think what weve seen here. Theres head and neck injuries from other people running into other people, not actually from the person moving themselves but from someone running into them. You actually become a projectile. Theres bodies above and below in these types of accidents. And also the luggage. Luggage isnt secure when you hop on an amtrak train. You put it under your seat or in the compartment ahead of you. Things to think about. David soucie thank you very very much. Were going to stay on this.

Im Brooke Baldwin. You can see media getting set up for another News Conference. We heard from philly mayor Michael Nutter. Now were about to hear from Temple University hospital as far as severity of injuries how many people theyre still treating at the hospital in the wake of this tragic and fatal derailment there last night in the philadelphia area. From the ntsb here, weve been reporting this on cnn. You you have it from the ntsb telling cnn that train is believed to have been traveling more than 100 Miles Per Hour when it jumped off those tracks. Again, thats twice as fast as the speed limit on that curve. The train was en route from washington, d. C. To new york when this happened in the philadelphia area. Right now we know seven people are dead, eight people are in Critical Condition, and more than 200 have been injured. Again, ntsb on the ground there, on the scene. We know that the search operation is continuing as well. They have expanded the search area because theres always the possibility that someone could have been thrown could have been ejected quite a distance from that train. Let me bring in Erin Mclaughlin shes got details as far as whats happening there. We heard from the mayor. Just to remind people, theyre still searching potentially for people who were on that train. Absolutely brooke. Thats because the 243 people that they believe may have been on that train, well not all of them have been accounted for. So theres been this very active and ongoing rigorous search process that went into the night last night and into the day today. Last night they actually brought out sniffer dogs to search an expanded search area. This morning they expanded that area once again the visual search continuing. It is very difficult, they say, for them to account for all 243 people that were on the train for a variety of reasons. It could be 243 people rather on the manifest of the train, for a variety of reasons. Its possible that not everyone had a ticket and boarded that train. They say its possible people on board the train simply walked away. This is a very detailed and ongoing process. As you say, seven People Killed. Authorities here saying it could have been much worse. I spoke to one man who actually walked away from the crash site. Take a listen to what he had to say, how he describes the moment of impact. Theres this split second where, to me, it felt like the car was lifting off the ground. It was lifting off the rail. We were going through a curve. Whatever speed it was going at pushed it out and pushed it up. We just flew. It almost felt like flying but it wasnt the right kind of flying. Well he was actually brought from the crash area to the hospital on board a police van with other potential victims. There simply werent enough ambulances in the area to treat all of the wounded. Incredibly he tells me he would travel on board another amtrak train again after all that. People need amtrak. Thats the way so many people get to and from work and home each and every day. Erin mclaughlin thank you so much in philadelphia. As you can imagine, so many people hop on the train each and every day or weekly. Right now Train Service along the east coast has been seriously impacted by that Train Derailment. All amtrak service, in fact between new york and philadelphia has been suspended. Brian stelter is in new york at penn station. I see a number of people at the big board behind you. How much has this affected people youre talking to . If you look behind me brooke its more delayed and canceled than it is on time. The trains that are running are only running to about trenton. Those are only local trains. Theres really no service between new york and philadelphia. Its like a big hole has been cut in the middle of the northeast corridor. The most important train line in the United States, and amtrak just a couple minutes ago said its going to be this way for a while. Theyve not been able to figure out thursdays schedule yet, but it looks likely that schedules will remain interrupted. This investigation will continue to take time. There really isnt a backup train line for amtrak trains. Its not as if theres ab second rail system that these trains can take from new york to washington and from washington to new york. Theres really just this one main line. And thats why people are seeking out the buses instead, flights instead. Of course because of supply and demand those flights now very expensive and those bus seats now very hard to come by very crowded bus lines and plane flights here between new york and washington. But there are people here as you can see. There are some local trains. There are some options, but it is making a big option for people who are thankfully here and able to travel but inconvenienced. I heard from one of my colleagues this morning that you cant take the train, the shuttles out of laguardia to washington. Its just it was packed for obvious reasons. No one really knows, brian, how long it will be before service is restored. I think thats the key, yeah. I was planning on taking the train on friday. Lots of people make their plans, especially Business People media people and politicians. These are the kind of trains where if youre on the train, you sometimes overhear politicians talking to people. Its very much a train line used by people to commute really between new york and washington with philadelphia in between.
