with more. bruce? >> reporter: mike, one more big hassle, not just for mark, but for amtrak as well. all mart service shut down, all amtrak service shut down, although i do hear a train coming at this point. there are tracks further away and that is where some trains might be able to get through. police are here on the scene. apparently about 10:00 this morning someone was walking along the tracks, got hit by a mark train. that train stopped there. then they halted all the mark service, all the amtrak service for about two hours. another mark train was allowed to come in, pick up all the passengers that were trying to get in to work, take them back to new carrollton. then they had to take the metro in from new carrollton. that's what's happening with some service now. but all the amtrak service shut down between dc and baltimore again. the lieutenant here, there's an amtrak train that is just now coming through. the lieutenant told me that the investigation, the dc police lieutenant told me the investigation likely will continue for sometime, but the body is off to the side of the tracks and they will try and allow these trains now to come through at a crawl while they continue the investigation. then if they have to take the investigation onto the tracks, they will halt service again. both mark and amtrak are telling me they hope to have normal service between dc and baltimore for evening rush. mike, back to you. >> thank you, bruce. we are also waiting on an update from philadelphia mayor michael nutter. when that happens, we'll bring it to you live. first, all eyes are on the engineer of amtrak 188, as the probe into the deadly crash begins. today, investigators are looking to talk to the train driver who was driving double the speed that was allowed in that area. today, he is saying he has no memory of that crash. we are also learning more about those who died in that violent crash. amtrak is working to get service back on track, as frustrated commuters look for ways to try to get to their destinations for the rest of this week. nikki burdine is live in philadelphia with the latest on the train's engineer and when we could possibly be hearing from him. >> reporter: all night and all morning, we've seen crews coming in here to the crash site, starting to remove some of the debris and replacing train tracks. meanwhile, ntsb investigators say they want to talk to that engineer. but it might not happen at all today because they say at the end of the day, he, too, has been through a traumatic experience. >> we want to find out what happened and why and we're not casting any judgment calls at this point right now. >> reporter: investigators say the engineer on train 188 was 32-year-old brandon bostian of queens, new york. although a top priority is finding out what happened tuesday night when the train derailed, bostian has to be mentally and physically able to talk. right now, he can't remember what happened. >> i want to point out that for somebody who's been through a traumatic event, this is not at all unusual for human behavior to have the mind blank out things like that. >> reporter: what we do know, the train was going 106 miles per hour when bostian hit the emergency brakes. at that point, only slowed down to 102, which is still more than double the speed limit around the curve. that's when all seven cars went off the track, killing seven people and injuring 200. about two dozen of those are still in the hospital. bostian himself was also hurt, but not seriously. >> we want to talk to this person and find out what his perspective was. >> reporter: was it human error? or did something else happen? a key safety feature called positive train control that could have intervened in either case was missing from the tracks. >> this is something that's been mandated by congress to be installed by the end of this year. it's designed to form redundency for human error so that when human error does occur, the system kicks in and will not allow the train to be oversped. >> reporter: any minute now we expect to hear from the mayor of philadelphia and then later this evening at 5:00, we'll hear briefing from the lead investigator with ntsb. meanwhile, an attorney for bostian says his client suffered a concussion and he was very distraught when he heard that seven people died in that accident. for more on the victims, let's go to cbs's jerikha duncan. >> reporter: five of the people killed in the crash on wednesday have been killed. jim gains, a 48-year-old father of two. and justin zenzer, 20-year-old naval academy mid shipman. >> he was wonderful, absolutely wonderful. everybody looked up to my son and there's no other words i could say. >> reporter: derek griffith was also confirmed as one of the passengers killed. he was the dean of student affairs in brooklyn, new york. his school released a statement calling griffith a pillar in the community, adding he will be sorely missed. 39-year-old rachel jacobs, ceo of a tech company, was a wife and mom to a 2-year-old. she was on her way home when the train crashed. in a statement to "cbs this morning," her family said she was devoted to her family, her community, and the pursuit of social justice. we cannot imagine life without her. near the crash site, the family of 45-year-old bob gildersleeve passed out fliers. the baltimore dad hasn't been seen since the crash. >> very frustrating, guys. not that they are not trying, but trying and coming up empty don't do it. >> we have no idea where he is, what hospital he's at. >> reporter: in an interview posted on twitter, his son told reporters his dad caught the train two hours after dropping him off at a sports practice. >> my name is mark. please help me find my dad. >> with the train tracks closed in philadelphia, many passengers say they have been left high and dry by amtrak, as they try to work to get to their destinations. one passenger found out today that many people are now taking travel into their own hands. >> are you going to new york, new jersey? >> trying to get to boston. >> reporter: cindy zip is giving away her greyhound ticket to new jersey today. >> so you decided to make that change because? >> because amtrak gets me quicker to philadelphia and then i can get to trenton and then to my destination, as opposed to all the way up to newark by bus. >> reporter: she says her trip back home on amtrak will save her time, though it involves three trains to bypass philly. others are waiting in long lines to catch the bus all the way up north, after their amtrak trip was canceled. >> we were left on our own. it's like you get a bus, find your own transportation. >> i had friends texting me who knew. i came home last minute just to see family. my friends were, like, are you on the train right now? it's terrifying. >> a minor inconvenience for me, even if it's a delay or taking a different form of transportation than is my favorite is nothing compared to the tragedy that happened. >> accidents happen and you just hope that they learn from those and make sure they don't happen again. >> reporter: at union station, wusa 9. >> our team is continuing to cover the following developments throughout the day. count on us for the latest information here, on air, and on the wusa 9 app. emergency crews have been called
