[Burnett:] The measles outbreak is growing tonight and infecting the most vulnerable, babies too young to be vaccinated, and we are now learning about new possible cases that an Illinois daycare, two infants have tested positive, three others believed to have been exposed. The spread of the virus which is now in 15 states has been blamed on the anti-vaccination movement. Our Ryan Young is OUTFRONT in Palatine, Illinois. It's just outside Chicago. And, Ryan, what are officials saying about these cases with these babies?
[Ryan Young, Cnn Correspondent:] Erin, you can understand the parents, of course, at first, were very upset when they heard the news about this. Officials say they have come to this day care and they made sure they did a thoroughly cleaning overnight. It was actually open this afternoon we watched as kids went in and out of this daycare. We tried to talk to a couple of parents. In fact, one parent said she had her kids here for the last eight years and believes they handled everything very well. All kids who haven't been vaccinated they have been sent home for the next 21 days. Of course, everyone is thinking about the five kids with signs of the measles and they're hoping they will pull through OK.
[Burnett:] So, do they have idea whether the cases here are linked to any other cases at this point or do they just not know?
[Young:] You know, honestly, that's the big question this evening. Everybody wants to track down where this started. What we're told now, they don't have an idea where this started. They actually believe more kids may get sick from this. Right now, what they're saying is they have done a thorough cleaning and, of course, they were very cautious out here in the parking lot with us this afternoon.
[Burnett:] All right. Ryan, thank you very much. It's so awful. Of course, those babies if they were under one, too young to have had the first of the two MMR shots that a child receives. And tonight, we're learning new details about the deadly collision of a commuter train and SUV that killed six people just north of New York City. Investigators saying today, the driver of the SUV, a mother of three, only had be 39 seconds when the crossing lights began flashing and the crash. Questions tonight about that driver and what she was doing on the train tracks. Our Poppy Harlow is OUTFRONT.
[Poppy Harlow, Cnn Correspondent:] Ellen Brody, a beloved wife and mother of three girls.
[Benjy Silvermna, Rabbi At Chabad Of Rivertown:] Her girls really adore her. Her husband and her are very close. It's just a beautiful family unit.
[Harlow:] Friends and loved ones grappling with how her life would have been cut so short.
[Unidentified Male:] It's tragic accident. It was not her. She was not careless person. She would not ever do anything that would put anybody at risk.
[Harlow:] Just 49 years old, Brody was driving the SUV that was struck on the track in the deadliest train crash in Metro North history. She's among the six people who perished.
[Unidentified Male:] A fire at the front of the train. One possibly trapped in the train.
[Harlow:] Rick Hope was in the car directly behind Brody, and recounted the fatal moment to the "Journal News".
[Rick Hope:] As we're waiting to cross the tracks the gate comes down in front of me and it comes down and hits the top of her car, unable to back up and I'm waiting for her to back up, but instead she gets out of car. She gets out and she walks around the back and looks at the arm that's on the back of the car. She looks at me. I gestured her to come back. I back up again further to even indicate there's plenty of room to back up and she turns, walks and gets back in the car, and slight hesitation and then moves forward, and at that instant, the train came.
[Harlow:] Why Brody's SUV was on the track is central to the investigation. Eyewitnesses say a separate accident backed up traffic and many drivers took an alternate route to avoid it. The NTSB is investigating if the detour played any role and is trying the recover data from the memory modules in Brody's
[Suv. Unidentified Male:] We found the crossing arm and the traffic signal. They both operated as designed. There were no problems found.
[Harlow:] Brody worked alongside Varda Singer and Virginia Zsa Zsa at this Jewelry store for ten years.
[Varda Singer, Friend & Colleague Of Ellen Brody:] She had a million dollar smile. She, to me, was a saint because she's one of the most selfless person I've ever known.
[Harlow:] She was driving home from work when she was killed.
[Unidentified Female:] In one word, she just had a beautiful soul. She looked for the good in others.
[Harlow:] Her husband Allen posting this message on Facebook, thanking all who shared their condolences. And, Erin, just tonight we have learned from investigators that the train was traveling within the legal speed limit when this horrific, horrific accident happened. Also this week, New York Governor Andrew Cuomo saying it does not appear that Ellen Brody was trying to beat the train but rather likely just confused. She leaves behind her husband, three beautiful girls age 15 to 22. She'll be remembered in services here tomorrow Erin.
[Burnett:] Poppy Harlow, thank you very much. Live where that horrible accident happened. I want to bring in rail record engineering expert Gus Ubaldi. And, Gus, just to give people a better sense of what happened here, I want to show them the Google Street view of the railroad crossing. This is where this happened. She drove her SUV beyond that white line that you can also see on your screen. Then the gate hit the back of her car. It's unclear if her car was actually on the tracks. It was past the gate. How far it was on the tracks, we don't know at this time. She got out of her car and got back in and drove forward instead of backward and got struck by the train. What could she have done?
[Gus Ubaldi, Railroad Engineering Expert:] Well, if she wanted to get off the tracks, she could have backed up. The gates are designed to be frangible. That means they're breakable. So, they would have broken, or at the very least she could have run away from the car, away from the crossing in the direction the train was coming. She would have survived. The train may not have hit the SUV or may have damaged front end. Whether the outcome would have been different for the people on the train, I don't know. That's what the investigators will find. But, certainly, backing up was an option.
[Burnett:] Right. And, of course, given that we know the car was partially on the tracks, that's what the man behind her said, there was room to back up. The NTSB is looking into this, Gus, as we know. Officials saying there were 39 seconds from the time the lights began flashing right at the crossing to when the train came through. Thirty-nine seconds sounds like a short amount of time. I'm sure that people who are waiting for crossings, it feels like a long time, people always want those times to be shorter. But is 39 seconds when you look at the accident happening now, enough? Is it safe?
[Ubaldi:] Well, I would have to say yes. The federal regulations say the minimum time for those lights to be flashing is 20 seconds. Each crossing is evaluated independently to determine what is sufficient time to alert the drivers that the crossing is going to be active for them to stop, and for cars, for example, at that traffic light at Taconic State Parkway for cars back up there to be able to clear so that there are no cars on the crossing when the train arrives.
[Burnett:] Of course, in a situation like this, you know, she perhaps realized what happened. You know, it's dark. The guy behind her as his lights, he's saying coming up. Maybe she didn't see him. Maybe she gets in her car to back up and she's trying to be calm and she's so calm and hits the accelerator and it goes forward because the gear didn't go into reverse. I mea, we just don't know what happened. But when you're in an emergency situation, all of a sudden, time seems a lot shorter.
[Ubaldi:] That's right. The best thing to do for drivers is to stop so you can see those flashing lights. Then whether you can see the painted line or not, you know you are safe, if you are behind that gate arm.
[Burnett:] Is there anything you can, they said the big shock they have is how it is possible that the train car itself was damaged and those people inside lost their lives, and the horrible tragedy of this. That has not happened before. They didn't understand how that could have happened. Is there anything that makes to you about that, about how hitting a car on the track, which frankly happens frequently, actually resulted in people dying on that train?
[Ubaldi:] I think it had to do with the fact the third rail was involved. Maybe punctured the gas tank and sparks, ignited it, and the air rushing by blew it back on the train.
[Burnett:] All right, Gus
[Ubaldi:] The investigators will find that out.
[Burnett:] Well, thank you so much for your time, we appreciate it, and your expertise. Thank you. And OUTFRONT next, NBC's Brian Williams facing new criticism tonight. Was his apology for a false war story enough? And the murder trial of former pro-football star Aaron Hernandez. What jurors will and won't see when they get a tour of Hernandez's home tomorrow.
