i'm don lemon live in philadelphia. that's it for me. our live coverage continues. from the cnn world headquarters in atlanta. >> the traj's engineer has told police he could not recall how fast the train was traveling, but sammel is in philadelphia and he joins us now live.

>> we're just learning new details about the 32-year-old engineer of that train that derailed in 106 miles per hour. yesterday he said he couldn't recall how fast the train was going according to a source. today, he's not saying anything at all. >> federal investigators hope this man, brandon bostian may know why an amtrak train jumped the tracks causing a deadly crash. >> you could just hear pounding. i was like, you know, maybe this is -- i mean, in the moment that it came to, it was alive. >> it appears speed is a factor. preliminary data showed the train was traveling more than 1100 miles per hour as it approach the turn just before it derailed. that's double the speed passengers speculate the train tried to make up time because the train left the station late.

>> you don't do reckless things. you don't endanger passengers by trying to make up time. i'm sure the seven people that lost their lives that we have confirmed, i'm sure they would not have minded being another 20, 25, 30 minutes late as opposed to dying unnecessarily in a train wreck. >> as the investigation into this crash continues, friends and families of the victims remember those who will never be seen again, like 20-year-old just justin. >> during the day, we heard from so many families that held out hope that they might find their loved ones in the hospitals or they might be returning home. now they find out they'll never

be returning again. >> while we have you there, we understand it's been a difficult day for everybody. we would like to clarify something. brandon bostian, he did give an initial statement, but since then he refused to give any form y'allal statements. is that what the what's going on? >> that's right. he sat down with police. they wanted to have a follow-up meeting with him today. he ended up walking out with his lawyer. the ntsb says they're hoping to speak with him in the next 24 hours as well as the other five crew who were there with him on the train. but for now, it appears that he's keeping a very low profile. >> i do want to touch base about what is happening on the tracks right now. what is happening at the scene in terms of how many cars are still left on the tracks and how many are being moved?

>> the crews are still working into the night. the investigators are combing into the tracks. the aerial ims show there are just two of the seven cars remaining there. the ntsb tells us they were removing the cars and taking them to a secure location where they're going to review them. it's interesting what type of information the cars on the track -- we know the train was going 106 miles per hour based on the angles of the trains and where they found each of these cars on the track. so so much of this information is being pieced together and giving us real information. >> and they're looking for clues, i guess, in the cell phone records of the engineer and also do we know where he is tonight? >> absolutely. they're trying to work on a warrant. in any of these types of situations, whether it's airplanes that go missing or trains that can crash, it's the cell phones that can glean a lot

of information. they want to look and see was he texting at the time of this incident, was he distracted? like i said, he's keeping a low profile. we don't know exactly where he is. i've been trying to track him down on social media. i found hits facebook profile, but within the past 24 hours, he's deleted his pictures, put up a blank black image in replacement of his profile. we see comments from other amtrak employees there saying they support him. we see other information on his linkedin profile, as well. we know he has about a decade of experience with the amtrak company. >> we want to talk about the victims. we know obviously seven people have lost their lives. we're learning a little bit more about those people. the latest victim identified as being derrick griffin ith. what more can you tell us about him? >> that's right. just a few minutes ago, investigators identified him. that's the fifth person they have identified when it comes to seven people who have lost their lives. he was the dean of student

affairs at city university in new york. and like i said, throughout the day we have been following the people that we were hoping would find someone they had talked about all day long. >> we also know they're removing some of the carriages and looking at the heavy debris. do authorities suspect there could be some victims beneath that debris? >> we have a list of names, many people have unlimited tickets because so many business people go back and forth between d.c. and new york. they have that list of names and they're having to piece that together with the families, with amtrak, with the ntsb right now, john.

>> stan, thank you so much. the theory is there still may be more victims amid the wreckage of that train. >> and since we found out the speed, the train engineer was traveling at twice the speed limit, there's been a lot of finger pointing about what may have caused the crash. >> yeah. the reports the engineer may have been speeding to make up time on the trip to new york. but then the ntsb investigator responded to that. >> i've heard that same story. but, again, i mean, you almost have to be an idiot to -- even if you're trying to make up time, to be doing 106 on a curve as opposed to maybe on a straightaway. so that is not acceptable. under any set of circumstances. i mean, look, let's be reasonable. people know from time to time a

train might leave late, a plane might leave late. but you don't do reckless things. you don't endanger passengers by trying to make up time. i'm sure the seven people that lost their lives that we have confirmed, i'm sure they would not have minded being another 20, 25, 30 minutes late as opposed to dying unnecessarily in a train wreck. >> i'm going to -- from such remarks. we're here to conduct a fact-based nonemotional investigation. to make comments like that is inflammatory at this point. we want to find out what happened so we can prevent it from happening again. >> do you think the mayor was wrong in saying that? >> you're not going to hear the ntsb making comments like that. we want to get the facts before we start making judgments. >> it could be up to a year before there is a final report issued. there will be a preliminary report out about 30 days from now. a lot of people wonder how could

this routine train ride end so violently? >> we look at how the train's speed could have played a role in the crash. >> there is a reason investigators need to look at excessive speed from the beginning. it started with things like this, this surveillance video. if you look at the train rushing by up there and you know the length of the locomotive, you can pick a fixed point and calculate the speed of that train. and that told us right away it was going much faster than it should have been going just 200 yards short of the crash site. why does that matter in the big equati equation? let's bring in a model of the train and talk about that. the locomotive is extremely heavy, about 97 metric tons or pushing up towards a quarter of a million pounds. if it's traveling at 50 miles per hour as it should be, all the physics here will cause some outward force towards the outside of that curve. not a tremendous amount. push it up to 100 miles per hour

or more and that force becomes much greater. gravity is low enough and it's heavy enough up here, it will stay on the tracks. that's not the case back there. the center of gravity is different back here. the weight distribution is different and that's why some passenger say they felt the car sort of flying up off the tracks. we know that can happen because we saw it happen in spain when this train crash occurred. the train was supposed to be going 50 miles per hour. instead, it was going over a hundred. watch you who it slings those passenger cars off behind it and they pull the locomotive off behind them. this is why investigators knew to look at excessive speed because it is something that they have seen before. >> with speed clearly being a major factor in this, a lot of people will be looking to the train engineer for answers. steven ditmeier is an adjust professor. >> he was involved in the creation of amtrak. he joins us now from alexandria,

virginia. steve, usually lawmakers rush to improve safety and spend money on infrastructure. just the opposite has happened after this tragedy. what is going on here with congress pushing ahead to cut amtrak's budget? >> this is a perennial problem that amtrak faces with congress. there are always tremendous pressures to reduce the federal budget, to reduce the federal deficit. however, usually at the last minute, various members of congress are concerned about cutting of trains to their districts so some money comes in, but never enough, really, for amtrak to be able to do its full capital program. >> and, steven, we don't know why the train wag traveling at twice the speed limit, but do you think it should be mandatory for there to always be two engineers, two train drivers in the cab of the locomotive at all times? what are your thoughts on that?

>> i tend to not believe that two are necessary at all times. there are a number of railroad operations around the world where there is a single driver in the cab. and they appear to be quite safe. but they also have a very robust train control system to prevent accidents. the positive train control system, had it be installed on this line and had it been functioning would have, indeed, prevented the accident. an additional engineer sometimes can -- or an additional person in the cab sometimes can prove to be a distraction. >> the budget keeps getting cut for amtrak, they can't -- but the other side of this, the track was inspected just the day before. some say this is about creating

infrastructure, is it? >> that is correct. the northeast corridor tracks are very old. some of the infrastructure was built in the 1930s. it was renewed in the 1970s and early 1980s. so there is infrastructure work that needs to be done. but it does not appear that infrastructure problems played a role in this particular derailment. >> and, steven, a lot of people are looking to the train engineer you now for answers to a lot of questions. but how does amtrak screen their engineers before they start work? what sort of training, safety training do they go through? >> most of the time, amtrak hires people as engineers from within the company. people who have been around the trains and who understand how the trains operate. they've run through an extensive

training program, first with books and lectures, then with simulators and finally with over the road service with supervisory engineers to make sure that the engineer is up to standards. >> okay. steven ditmeyer, thank you very much. we appreciate your insights. earlier, one of the survivors, caleb burnam spoke to anderson cooper about his experience on the train and how fellow officers stepped up to help the injured. >> how are you feeling? >> a little banged up, but it's getting better and i know that there are a lot of people that couldn't walk away from the accident, so i feel very blessed. where on you on the train were you and how did you feel? >> i was in the very last train. for me, it was a very sudden incident. it started off with a little bit of shaking and i was sort of minding my own business, in my own world, lisping to my ipod. i noticed computers shaking a little bit. >> so you didn't actually hear

anything? >> no. i have heard reports of people hearing a buckling sound. i was just dazed off, listening to my music, that sort of thing. all of a sudden, i felt a little bit of a shake. saw the computer kind of floating. i was on the other side. >> that quick? >> to me, it was that quick. it was -- >> do your car tip over? >> so the last one was sort of at like a 30-degree angle at the very end. it was rattling around and it felt like the entire time when we were inside the train trying to figure out what was going on, trying to assess the damage and help anybody that was in need. it felt like it could go over. and we didn't know if it was smoke or being filled with dust and so it was a very traumatic situation inside. ultimately, you know, we saw a lot of people step up, recognized there were people in need and there was a lot of people on the train sort of flocked to them. they were picking them up, assisting them down the hallways, moving the chairs completely disconnected from the

base. >> chairs were ripped out of the base? >> ripped out of the base. >> so 30 degrees wasn't flipped of, still chairs were ripped off? >> you would have thought this they rolled. and so people were trying to determine, do we kick the windows out? how do we get out of this thing? >> and is it dark? >> it was dark, yeah. so from what i recall, i can't recall where the light was coming from, but there was some light because i remember seeing silhouettes. eventually people pulled out their cell phones, holding up the light trying to search for it. but an absolute tragedy overall and we're very fortunate to be able to walk out. i've seen some very sad things. there was some young ladies on the train that have lost their teeth because of what happened. they were bloodied on the entire train. they were some stuck on the ground and a group of people trying to help them lift these ladies up. >> an incredible story of the passengers who managed to get off the train. we'll have much more on the

welcome back, everyone. about 24 hours has passed since the deadly train derailment in philadelphia. seven families are now in mourning. investigators are combing through. take a look at the video here. mangled wreckage. you see commuter cars turned over on their side. the crash killed seven people and injured more than 200. a lot of passengers on that train describe being thrown against the wall and pretty much each other. >> officials say the train was going more than twice the speed limit of 50 miles or 80 kilometers per hour. authorities have identified the train's engineer as 32-year-old brandon bastion. he told police he could not remember how fast the train wag moving at the time of the crash. >> investigators have recovered

the train's black box or event recorder as it's known and are looking at it for clues. >> one person involved in the crash -- >> after helping his mother to safety, he went to the back of the wreckage to help other passengers out. he and his mother describe the scene to our anderson cooper. listen. >> everything was going fine and all of a sudden for about two seconds, our car started to shake and before you knew it, we were all up against the window. our car was on its side and everyone was on the ground. the car finally stopped. i got up and the car was smoking. so everyone's first thought was the car might explode. so let's get everyone out of here and there was a door open about eight inches. and it was enough room to squeeze people through it.

so the first priority was, obviously, to get my mom safe. so i got her out. and looking around the car, i saw that there was so many people in much worse condition than i was, i was up, i was able to walk, so i just did what i could to get people out of that car. >> and, june, did you notice the speed of the train at all priority the crash? did it seem like it was going fast? some people say they felt like it was going too fast. >> i didn't feel that way. it was moving. i didn't notice any difference. people were traveling. >> and i understand that when it derailed, joan, you went flying and actually flying toward your son. is that right? >> i went flying towards the windows in the side of the car that was going down. and we were sitting in the front while there were many large pieces of luggage that one hit

my chest, one hit my head. i was covered with all this luggage when my son found me. >> what is going through your mind in a situation like that, joan? is it happening so fast that you don't think or can you -- can you tell me what it's like? >> it was very scary, but, you know, i think i started to panic a little bit. but my son just kept calling my name and he found me. he got me out. and made sure that i got out of the train and then i could focus better and to see if i could help others, as well. >> max and his mother are clearly fortunate to have survived. seven others were not so lucky. a fifth victim from the train crash has now been identified. his name is dr. derrick griffith. he was the dean of student affairs at edgars college in new york.

>> the survivors of amtrak train 188, it was a moment of chaos and horror. >> i was thrown against the girl next to me, against the window. and people from the other side of the aisle started falling on top of us. so somebody's leg hit the side of my head. the rest of her body must have been in the luggage rack. >> among those killed, 20-year-old justin zemser, a midshipman on his way home to new york. >> this is a painful day for that midshipman's family, for the entire academy community and for all of those affected by this tragedy. our thoughts and prayers are with them. >> 48-year-old jim gaines, a fare of two who worked for the associated press, rachel jacobs, chief executive of a small tech company who was heading home to new york. the 39-year-old is survived by her husband and 2-year-old son. and wells fargo executive abid

gilani also died in the accident, a company spokes woman confirmed on wednesday. there was an untold number of passengers still unaccounted for, including robert gildersleeve, a 45 yield executive and father of two from baltimore. >> i was surprised that there were a few head injuries and there were many, many patients that had rib fracture. >> what does that tell you? >> that there was a high energy crash. >> some of those treated and released from the hospital eventually made it to new york's penn station earlier today on another train while the search for those still missing continues. >> we're going to take a quick break on cnn. when we come back, we will have much more breaking news coverage of the philadelphia train derailment. stay with us. introducing the kelley blue book price advisor.

welcome back, everyone. we are following breaking news out of philadelphia where ntsb investigators are trying to figure out what caused that passenger rail crash including seven people. >> now live trt crash site, the cranes are there. they've been there for a while. they're now removing the carriages. where are they taking them and what sort of information do they hope will be reveekd from the wreckage of those carriages? >> we're seeing the last group

of semis, these really enormous semis leaving the crash site which is just behind us here. as they move out, we can see more into the crash site and see police still working around the area. it looks like there are just two of these train cars left at the crash site and the authorities tell us they're moving them to a secure location, they say, where they can review all the material inside them and they can determine more facts about how fast the train was going and really give them a lot more information. now, it's interesting because they already have the data recorder's, the so-called black box. that's going to tell them -- it's going to confirm the speed. it's going to tell them about throttle. it's going to tell them about breaking. but there's these cameras that they have on the train. that doesn't just tell them about the train, that tells them about the condition around the train, around if train trackes and of the train tracks. so this is all the material that

these investigators are going to be combing through over the next 4 hours. >> and obviously, after every train crash, there's a talk about positive train control that would have prevented this accident from happening. give us a sense of what exactly it is and how it works. >> well, in the northeast corridor, these trains that go-between cities like washington, d.c. and new york, as was the case, was supposed to be the case with this train, this type of system is already in place. it's automated speed control. so if the train doesn't slow down, if the engineer doesn't bring it down to the speed it should be, it automatically slows down. it was quite incredible today to hear an ntsb spokes person to come out here and say this stretch of rail does not have this and if it did, we believe this train accident would not have happened. so clearly a lot of people, not

just the ntsb, but passengers, so many who use this train for work or the commute are wondering if the government needs to invest more in putting these types of automated speed controls throughout the entire northeast corridor of the united states. >> it costs $5 million and it will cost another $5 million for the project and they're pushing it back. this is the busiest rail corridor in the u.s. what has been the knock on effect of our travelers? is there any idea how long it will be before services return to some sort of normalcy? >> well, to get down here, for instance, i was coming from new york and there was no option for trains. that is still closed. a lot of people are having to resort to buses and vans. we just came down in a car, it would be much faster. amtrak has been here on the scene providing many of the people who are affected by this with buses, with vans to get where they are going. it's affected a lot of the businesses around here. people are saying they've lost a lot of money because, really,

it's just gridlock around here. they can't get through. police have been stopping everybody. so it's affecting a lot of businesses, local, but you have to know that this is really an artery for so many people. we've seen a lot of executives who are on this train because this train shuttles so many people from d.c. to new york. >> 2200 trains a day between boston and washington. sam burke, thanks. >> here is the thing. when they interview this train engineer, when they talk to him, just to play devil' advocate for one second, sl any justifiable reason, is there any excuse he could give as to why he was traveling at double the speed limit? >> well, it may not be a human error. it could be there was a problem with the brakes, a problem with the throttle, some other technical and mechanical issue which they'll look at. the event recorder should reveal that. that's what the investigation

will come out. it looks that way, but a lot of it was saying don't jump to judgment. let's have the investigation and -- >> and the ntsb hasn't spoken to the train engineer yet, either. we're hearing more about the derailment from the passengers who survive it. >> gayle rooney describes the scene to don lemon. >> so i take the train home all the time. this is my usual train. everything is always fine. you're on a train and you assume nothing is going to happen to you. trains are supposed to be the safest method of transportation. it was so horrific. there were people catapulted up into the lobby. the woman behind me lost somee teeth. everybody was gushing blood, everyone was screaming. it was such a state of panic and shock. you never expect something like this is going to.what, especially not to a train. >> yeah. and so the people were -- you said it was a state of panic.

how seriously were people -- you described some of the injuries, but how seriously did you see people who were injured around you? >> so the person mind me lost an arm, unfortunately, and a lot of the women in front of me were bleeding from their heads. and that's about it that i saw on the train. but at the hospital, there were a lot of very seriously injured people, unfortunately. >> my goodness. we saw some of the video coming in last night and today where they are saying mo move forward, come this way, keep walking, keep walking. was there confusion, gabby, at all about how to get out of the train and what to do? any confusion? >> well, at first the train flipped completely over. so we all ran towards the doors and the train, there were people yelling that we were off the bridge. obviously, there was a huge state of panic that we were going to fall into some water. so everyone was trending towards the door. someone managed to force the

door open and a lot of people leapt through the window. >> what happened when you got out through that window? >> we were told -- everyone was screaming that another train might come along, so we were told to run as far as you could through the trains. and i was on the phone with 911 as i was running through woods and we all -- a lot of the people in my car, because i was in the last car, made it safely over the second set of train tracks into this little area where i could call 911 and everyone was just helping each other. the less wounded were helping the more severely wounded and we were just trying to describe our location to the 911 dispatchers so they could get to us as soon as possible. >> that is interesting that you mentioned that you were on tracks and that they were active tracks and at any moment another train could have come by because there was an accident. and who knows if right away they were alerted. you said you may have thought that you were out of danger, but

you weren't. you weren't sure. >> yeah. it was terrifying. >> so you're on your way back from college. what did you tell your -- what did you say to your mother? so i called my mother as soon as we got to the other set of the tracks through the woods. the first thing i said was i'm okay. at that point, i didn't think i was severely injured. i was able to walk. so i just said i'm okay. she asked if i was safe i said yes, i'm safe. there's been a terrible train accident that i was involved in, but i'm okay. and my dad met me at the hospital. >> you were one of the first people at the hospital. what was the scene like there? >> so i was -- i wrote in a cop car snet instead of an ambulance so they got us there really quickly. i was with another girl who hurt her back. to my knowledge, we were the first at the university hospital. they were ready, ran to the car,

got us out, got us in windchi wheelchairs and triaged us. >> it's tough to relive this and i want to thank you. is there anything you would like to say to folks about this experience, to people who were watching? >> yeah. i wanted to emphasize just how amazing all the medical staff was both at the accident as well as in the hospital. and my thoughts and prayers are really with all the victims of this accident. >> yeah, absolutely. and we'll take a short break. when we come back, we'll continue to follow the latest on philadelphia and the train derailment which left seven people dead. my friends said i was crazy., why would i stay in someone else's house? but this morning, a city i've never been to felt like one i already knew. i just wanted to thank you for sharing your world with me.

speed lip, that speed limit being 50 miles or 80 kilometers per hour when it hit a curve and du jumped the rails. the engineer, 32-year-old brandon bastion did hit the brakes, but that wasn't enough to prevent this tragedy from happening. >> investigators are now analyzing the black box to find out exactly what went wrong. now to more on a story we brought on wednesday. south korean intelligence officials say north korea executed its defense minister for general disobedience to kim jong un. >> a public execution of one of north korea's highest officials. south korean intelligence says kim jong un had his defense mip sister shot by anti-aircraft guns as hundreds of north elite watched.

the reason? being disloyal. >> this was a big deal. he was a survivor. >> he was a kim family loyalist who spent years working under kim's father to become north korea's second highest military officer. south korean lawmakers who attended an intelligence briefing about his death tell cnn he was accused of second-guessing kim's orders, even dozing off during events. >> these disturbing reports, if they were true, describe another extremely brutal act by the regime. >> it's not the first time the leader has eliminated his rivals as he struggled to maintain power. a public execution by anti-aircraft machine gunfire of a group of people sometime last october. in 2013, kim killed his own uncle, once a member of his inner circle, for treason. a north korean defector tells cnn kim then poisoned his aunt

for complaining about her husband's execution. south korean intelligence says kim had 15 top regime officials killed this year alone. charges a top north korean official dismissed as, quote, malicious slander. but news of the execution comes as kim backs out of vladimir putin's massive military parade marking the end of world war ii. russian officials say it was for internal reasons. would that prompt one of kim's inner circle to kill him or stage a coup? >> when we see these sorts of very high ranking people bumped off like this, there might be a group who feel that they're better off under a different leadership. >> thanks for that report. now, after two earthquakes within weeks, there's an urgent need for support where the death

toll in nepal stands at 76. 18 others were killed in india and china. >> meanwhile, no sign of an american military helicopter that disappeared on tuesday. it was trying to deliver eight with six american marines and two nepalese service members on board. here is phil ripley with more. >> tend of a full day of serving and still no sign of those missing u.s. marines. this army outpost the center of a search and rescue effort but also for the many people still trapped in the mountains. one by one, military helicopters carry survivors from the earthquake ravaged himalayas. the government hopes to focus fully on relief. but instead it's occupied by urgent rescue from tuesday's massive earth in nepal in just over two weeks. i have never seen this kind of devastation in my lifetime. >> many have nothing left but each other. >> we were hearing that in some places most of the houses

collapsed. >> yeah. they're almost -- damaged. most. >> most of the nepalese military's 90,000 troops are responding to the earthquake, joining soldiers and relief works from around the world. each helicopters brings in another load of people and they all come to this triage center for first aid. there are so many people who need help right now and m of them are still in the mountains waiting to be rescued. the 7.3 the quake triggered landslides, toppled buildings and forced many families back outside, too scared to sleep in their homes. >> yew afraid your home will collapse? >> yeah. >> because of the cracks in the wall? >> yeah. >> that might be an awful feeling. >> yeah. my grandma, she cannot run and -- we are here. i don't know. we don't want to go home right now. >> two families share one tent,

makeshift shelters keep them dry for now. >> are you afraid of when the monsoon reigns? >> yeah, yeah. the rain may come and make it with. so yeah, everyone here is scared of the rain. >> but fear doesn't stop the people of nepal from doing what they can to bring some semblance of a normal life, despite all they've lost, they still have hope. >> humanitarian aid is slowly trickling into the hardest hit areas. these helicopters are being loaded with supplies and each shipment is flown to the himalayas, where people are in need of food and water and medicine. cnn, kathmandu, nepal. >> breaking news right now into cnn, at least a 45 people are dead after a fire at a footwear
