Number one in just 60 seconds. Good evening. Thank you for joining us. At the height of the Holiday Travel season, a deadly Train Derailment near seattle. An amtrak tran careens off the tracks on a new route designed to save time. Tonight questions about why it went off the rails. Abcs claytosand oh my god reporter its every commuters worst nightmare. Amtrak 501 north, over. Amtrak 501, emergency, emergency, emergency. We are on the ground. We are the bridge oni5, derailment reporter a train traveling seattle to portland, derailing while crossing an overpass. Theyre requesting all possible units responding on the freeway. Reporter at least three people dead, on board approximately 84 passengers and crew members, 13 of 14 train cars jumped the tracks. Some spilling over onto busy interstate 5 below. Oh my god that train is derailed over the freeway. Reporter some train cars suspended in the air. Others crushing vehicles below. Within minutes interstate 5 awash with red and blue lights. That is crazy. People were in shock. And a lot of them, they just went and they sat down with their faces in the palm of their hands like, whats happening . Reporter daniel and his girlfrie alicia were driving by and stopped to went down und freeway and started working my way through those trains. One of the trains had tipped upside down and spill the passengers out. Then the train came down on top of them. One of the gentlemen had been thrown from the train. He was one of the fatalities. Reporter 100 people, including passengers, crew, and motorists below, rushed to nearby hospitals. There are at least three fatalities. Amtraks cascades train number 501 was on its inaugural passenger run, traveling down a rail bypass formerly used for freight but was modified to carry passenger trains. The train departed seattle at 6 00 a. M. , scheduled to reach portland at 9 20. 7 30 a. M. , passenger chris carnes, chair of the Pierce County transit advisory board, wow this train is fast, we are passinupraffic on i5. Moments later around 7 34 a. M. , a locomotive and 12 cars careening off both sides of that very overpass. We were going between 70 and 80 miles an hour. And we heard a creaking. A little bit of a creaking sound. Then the train started to wobble. Reporter just below that busy southbound traffic. And then we were catapulted at the seats in front of us. The next thing we knew, our car had crumpled, and we were down an embankme. I looked around, there was windows and glass and a particular smell that i cant really describe. Reporter the conductor radioing for help. Hey, guys, what happened . Coming around the corner to take the bridge over i5 there, right north into squally, we went on the ground. Is everybody okay . Im still figuring that out, we got cars everywhere and down onto the highway. As soon as i know about exactly where all my train, ill let you know. The first car was on the ground, the second car was the passenger, was down. The third was dangling. The fourth and fifth were up on the track. About 20 ems started flooding toward the area. A lot of people in the northbound lane was going over to help as well. Reporter the cause of the derailment is still being investigated. Everyones familiar with black boxes on airplanes. But trains also have similar recorders. Theyre capturing parameters such as speed, throttle position, braking, and even whether or not theyre blowing the whistle or the horn on the train. So these devices can be really helpful to investigators to really corroborate with what theyre hearing from witnesses. Reporter but the owner of the track where the train derailed confirmed to abc news that the sed limit on that portion of the track is 30 miles per hour. Officials have not yet confirmed how fast this train was traveling. Earlier this month, the mayor of lakewood, washington, expressed concerns about safety. Come back when there is an accident and try to justify not putting in those safety enhancements. Or you can go back now and advocate for the money to do it. Because thibudget project was ner when we got to the scene it was obvious there were fatalities and injuries. Multiple cars and trucks were struck by train cars that left the tracks and went down onto the road. The people in all the vehicles, even though when you see the pictures, its rate horrific, at this point nobody in any of the vehicles is a fatal. The fatales are all contained to the train. Reporter a medical tent was set up nearby to help triage the numerous victims. Nearby hospitals asking for blood donations. We also have crew members who have survived. And so interviewing them to understand what was going on immediately prior to the derailment is going to be very important for the investigators and theyll want to do that as soon as possible. Reporter todays denmarks the second derailment this year in the same county. The first back in july when a passenger train carrying 267 people skidded off the tracks. They slam on the brakes and were all of a sudden tilted. Reporte no casualties, only a handful of minor injuries. However, an investigation later showed the trains engineer was driving too fast, triggering a derailment switch on the tracks prior to reaching a draw bridge. Notify amtrak to shut down the entire northeast corridor. We have a major event here. Reporter speed also a factor in 2015 when an amtrak passenger train traveling twice the speed limit sped off the tracks outside of philadelphia. Crawl forward, sir reporter this is all tafs le that was left of the train, carrying 238. The derailment killing eight, hundreds injured. A report would later note a culture of safety lapses at amtrak was responsible for the collision, adding the accident could have been prevented if the tracks had been equipped with a system that enforces speed restrictions, known as positive train control, ptc. Positive train control was mandated by law, but amtrak has been very slow to implement it. What the u. S. Is putting in right now is a rudimentary auto pilot that in aviation we would find in the 1940s. Reporter sound transit, the owner of the track, says ptc was installed here but in a phone conference amtraks ceo Richard Anderson told reporters ptc was not activated. He did not want to speculate on the speed of the train or scenarios that could have caused the derailment. Theres still too much room for human error. Theres still too much old technology. Theres old track, old trains. Were dealing with a train system thats decades behind the rest of the world. This is a tragic event. On behalf of everyone at amtrak i want to express that were deeply saddened by what happened here today. Reporter back in washington, debris and twisted wreckage still block two major transportation veins. Theres a thorough investigation under way to determine what happened. Reporter tonight investigators trying to answer that lingering question. What caused the train to derail and claim one too many lives . Im Clayton Sandell for nightline in dupont, washington. Our thanes to clayton. Next, no more mutants, wolverine is ringmaster. Hugh jackman trading in claws for a cane and top hat in the greatest show man. My 3month old business. Plus. What if this happened again . I was given warfarin in the hospital, but wondered, was this the best treatment for me . So i made a point to talk to my doctor. He told me about eliquis. Eliquis treats dvt and pe blood clots and reduces the risk of them happening again. Not only does eliquis treat dvt and pe blood clots. Eliquis also had significantly less major bleeding than the standard treatment. Eliquis had both. And that turned around my thinking. Dont stop eliquis unless your doctor tells you to. Eliquis can cause serious and in rare cases fatal bleeding. Dont take eliquis if you have an artificial heart valve or abnormal bleeding. If you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. While taking eliquis, you may bruise more easily. And it may take longer than usual for bleeding to stop. Seek immediate medical care for sudden signs of bleeding, like unusual bruising. Eliquis may increase your bleeding risk if you take certain medicines. Tell your doctor about all planned medical or dental procedures. Eliquis treats dvt and pe blood clots. Plus had less major bleeding. Both made eliquis right for me. Ask your doctor if switching to eliquis is right for you. New ultimate surf turf event.

Barnum in the musical greatest show man, a show creating awards show buzz. My nightline coanchor juju chang takes her turn in the ring. Reporter wolverine is trading in xmen claws tell me do you want to go reporter for tophat and cane. The everversatile leading man hugh jackman depicting a decidedly more human hero. P. T. Barnum. No one ever made a difference by being like everyone else. Reporter in the greatest show man. As a ring master you have a cane, a hat. Nice flair. I like the panache. Put the hat on the head. Oh, come on. Reporter with those tricks nobodys better than jackman for the role. I had to do it with my eyes closed. Thats incredible. There you go. Im showing off now. So we had ten weeks of rehearsal that i was vocally preparing for two years before. And i literally came straight from shooting logan to shooting this. I had a weekend off, then i came to it. I can tell you, this was tougher physically. What do wolverine and p. T. Barnum, if anything, have in common . They have some things in common. On the surface, very different people. But they both have fight. Push them up against a wall, back them into a corner, look out. And ive got a little bit of that. Reporter the movie an overthetop homage to the father of show biz. A musical take on the real life of pt barnum. The risktake history founded the Barnum Bailey circus in the 19th century. Seven years in development . And a half. And a half . Not that anyones counting. Whats it like after all those years to see it come to life . Its a great thrill. Its nerveracking because i care so much about it. We have become a family. Also ive been around long enough to know these things dont come along very often. I think ive had an idea reporter the film follows his journey in creating the firstever circus. Putting together a show. I need a star. Reporter rallying a group of outcasts and misfits into a spectacle. United against backlash and bigotry. There is a strong current of taking outcasts, allowing them to come out of the shadows. Yet at the same time its met with some of sort of mob mentality. Right. Are there sort of parallels in Current Affairs that you draw on . Absolutely. Because art always reflects life. As we develop this for seven years, the theme of inclusion, the theme of tolerance, came further and further to the surface of the movie. Im an australian. Ive come all the way across the world to america to live here. And i have only ever felt welcomed. Supported. And i just have a feeling now, were just retreating a little bit. Reporter the films glowing depiction of barnums life makes some selective jumps. Glancing over accusations that he took advantage of, even exploited, people who were social pariahs. P. T. Barnum is a bit of a flawed hero in real life. Yeah, hes definitely a flawed character. I think thats why i was drawn to him. Was he probably using the bearded lady and tom thumb in the beginning to sell tickets . Yeah. He was. But what happened was, he genuinely created this family. Im not sure if thats what he intended in the beginning. Reporter barnums famed circus closed its doors for good earlier this year amid dwindling ticket sales. After years of animal cruelty allegations by rights groups. In the movie you ride a cgi elephant. Yes. Was that fear of the cruelty to animals accusations . We were never going to use animals in the movie. Everyone in the film totally agrees animals should not be used in circus or form of entertainment in that way. Thats a bygone era. This is 1850. It is there and thats why we used cgi animals because we dont want anyone to think we were exploiting or celebrating that in any way.

That characters final performance hit the screens earlier this year in logan. You watched that final performance with tears in your eyes. Oh, yeah. Not just in my eyes. Rolling down my cheeks. Ill be honest. I was so nervous to see that final showing. And i just really was pinching myself and felt so blessed and so relieved. Because i knew it was my last. And i wanted to go to sleep at night for the rest of my life knowing that id made the movie that id always felt was there. Reporter in this film jackman joined by a powerhouse cast. Michelle williams as his everpatient wife. Zac efron as his junior partner. What percentage of the show would i be taking you talk about transcending class in this movie. In some ways barnum, the story of barnum is the story of the birth of show business, but i would go further and say its the story of modern america. In the beginning there were limitations of your class, of your background, of the family name. There were certain places you couldnt go. Barnum was one of those. Reporter a bigbudget hollywood musical still not a sure thing, even when the composers are the oscar and tonywinning duo behind la la land and dear evan hansen.
