A train plowed into a backhoe, killing two amtrak workers who were using it and injuring nearly three dozen passengers. Federal investigators want to know why the equipment was on the tracks in the first place. Nbcs tom kcostello covers the ntsb. Good morning. Good morning. Investigators sent the black boxes and the trains inward and outward facing cameras to the lab in washington. The question this morning, was there a major communication breakdown . How could this train be operating on the same tracks where a piece of Construction Equipment was also working . Reporter overnight, the wreckage cleared after yet another tragedy on the tracks. We now have our second doa located at the impact site of the backhoe. Reporter two amtrak construction workers dead after a passenger train slammed into their backhoe sitting on the tracks. Of the 330 passengers and 7 crew members on the train, 30 were taken to area hospitals. None of the injuries life threatening. Passengers described a harrowing crash and explosion. There were people pretty bloody because it was an explosion. We got off track, and then it was like a big explosion. Then there was a fire. Reporter it happened just before 8 00 a. M. On sunday. Palmetto train 89 from new york to savannah, georgia, had just passed philly. As it approached chester, p. A. , the backhoe was right in its path.

Reporter ntsb rail investigators are on the scene looking for clues. We will be looking at mechanical operation, signal, track, Human Performance and survival factors. Reporter it was just last may that eight passengers were killed, 200 injured, when a speeding amtrak train derailed north of philly. That investigation still underway. Now south of philly on the busiest commuter train tracks in the u. S. , another deadly accident.

Amtrak cautions there will be some residual delays between wilmington and philly this morning. Meanwhile, there was another accident in illinois when a car collided with a train bound for california. The Fire Department reports one person in the car was killed. Nobody on the train was injured. Tom costello in washington, thank you very much.

We have this covers and well start with nbc National CorrespondentPeter Alexander who is in lacrosse, wisconsin, this morning. Good morning to you. Donald trump will be here shortly. This is a pivotal state for trump and cruz. Cruz trying to show hes expanded his appeal. That he can win in a state like wisconsin with a much more moderate conservative base. Reporter 24 hours out, the candidates are on a collision course in wisconsin. The stop Trump Movement nearing its first victory. You shouldnt be littering up the process because thats what hes doing. Its really a disgrace. Reporter kasich firing back on twitter. Thats not how our republic works, donald. Well keep fighting until someone reaches a majority of delegates. Priebus says the candidate is someone who is running. Reporter trump is said to not have beefed up on policy. I dont care if youve done it all your tell. Reporter the billionaire telling the Washington Post, im the lone ranger, warning the country is headed for a massive reception and vowing hed be able to erase the 19 trillion National Debt over eight years. A claim most economists claiming impossible. With melania on the trail, trump is backing off on the war of wives. Acknowledging his retweet of this unflattering picture of heidi cruz was a mistake. His exsaid, we need immigrants. Who is going to vacuum our living rooms and clean up after us . Americans dont like to do that. Meanwhile, Hillary Clinton is trailing Bernie Sanders ahead of tomorrows primary. I still have work to do to win the nomination. Im going to keep reaching out to every voter everywhere in these remaining contests. Reporter sanders arguing hes more likely to beat trump. I think the secretary is getting very nervous. Poll after poll shows us doing much better against trump than she is. Reporter Chelsea Clinton calling trumps abortion comments wrong and offensive to access hollywood. The universal condemnation is a really important message, candidly. Reporter all of it fodder for snl. As a woman, how can you keep defending mr. Trump . He retweeted a sexist, unflattering photo of ted cruzs wife. So no, okay, so no, okay, so actually, that was an accident. The bitter democratic divide turning into a debate over debates. For the republicans, its now a state by state fight for delegates. This past weekend, north dakota and tennessee, it appears ted cruz outperformed the performance. Matt and savannah . Peter alexander on the trail for us, thank you. Lets bring in nbc news political analyst Nicolle Wallace and mark halperin, the managing editor of bloomberg politics. Good morning. Sometimes you cant look at the week ahead until you put a period on the week youve experienced. On a scale of 1 to 10, 10 being terrible, what kind of a week did donald trump have . 37. That bad . There is material to go against him. 8. 32. Not that bad . I try to stay by the rules, unlike nicolle. He still has a huge delegate lead. I dont think his supporters were bothered by anything that happened. It emboldened the people. So many of the comments he made last week, mark, got him into trouble. Instead of staying quiet, he goes out and gets an interview to the Washington Post over the weekend. One of the things he says is the country is headed for a very major recession. If any other candidate said that, if the president of the United States said that, the markets would go crazy. Its bad timing for donald trump to be doing controversial things. The party is focusing on electability. Phycology matters as much as delegates right now. All the comments make people look at him in the party, some of the people, and say, maybe this isnt the right person. Speaking of phycology, there was a write up in the New York Times that collected the evidence on how trump might do in a general election. Mr. Trump has become unaccessible to broad swaths of americans, including large majorities of women, nonwhites, hispanics, voters under 30, those with college degrees, and independents, too. The phycology of trumps supporters is what you have to watch. They are he said a few weeks ago he could walk out on fifth avenue and shoot people and not lose support. That may be true. It turns out, you cant shoot from the hip on national security. All those groups you named, especially women and independents, they dont do reckless things in the voting booth. Hes feeling like a dangerous and reckless choice on matters of national security. As we look to wisconsin tomorrow on the democratic side, mark, if Bernie Sanders wins in wisconsin, and then has two weeks of no other contests leading up to new york, whats the effect on the Clinton Campaign . Again, its phycology. Hes going to draw huge crowds here. Theres going to be a debate here. If he werent behind in delegates, this would be a tossup race. He has more money, raising more, states that are favorable coming up and a line of argument against her that is appealing to democratic voters. She has to have two weeks of pain she can end if she wins in wisconsin. Mark and nicolle, appreciate it. Breaking news overnight. Happened at one of the nations busiest airports.
