Some of the passengers on the derailed Amtrak train are talking about the terror they felt when a train went off the tracks in Missouri after striking a truck on Monday afternoon.

"It was very overwhelming," said Jason Drinkard, a passenger who was traveling to Chicago when the train derailed.

"You would never think your train would derail," said Antwoine Matton, another passenger.

Many passengers said they are lucky to be alive. At least three people died, including two on the train and one person in the truck, authorities said.

"It was something that you never think is going to happen, but when it does happen, it's far worse than anything you could have imagined," Drinkard said.

Drinkard, a high school teacher, was traveling with his wife and six students for a Future Business Leaders of America conference in Chicago when he felt the crash.

"Just the carnage, watch all these people who can't walk, or … and it wasn't just the passengers, even the employees," Drinkard said.

Matton said he was on his way to a wedding and had only been on the train for an hour and 30 minutes when it went off the tracks.

"I see people grieving right now so I'm like, this is crazy. Me and my friend walked out just fine," Matton said. "The fact to see so many people come here, too, to help out to give food and water, that's just amazing to me."

Some of the passengers on the train were from as far away as New Mexico and California. Some had been on the train for a day or two. Amtrak's Southwest Chief Train 4 originated in Los Angeles and was en route to Chicago when the crash happened.

An Amtrak train derailed in rural Missouri after hitting a dump truck at a highway-rail crossing. Four people died.

In 2021, 105 people died in incidents at highway-rail crossings like the one in Missouri. 

"It's a lot less than the number of people killed in traffic accidents, of course," University of Delaware Professor Allan Zarembski said. "But it's a significant number."

There are far fewer deaths compared to decades ago. But in recent years, the rate of incidents at highway-rail crossings has been increasing — up 32% in 10 years. That's according to records Newsy reviewed at the Federal Railroad Administration.

The agency is researching why mishaps are climbing, sharing these possible explanations: More rail and highway traffic, development along rail rights of way and individuals engaging in risky behavior.

"Unfortunately, a large number of these accidents are people trying to beat the train," Zarembski said.

The National Transportation Safety Board is looking at another possible factor in Missouri. The crossing did not have an active warning device seen at busier intersections, like a flashing sign or a gate that comes down. 

"There were no arms, there were no warning lights, there were no bells," NTSB Chair Jennifer Homendy said.

About half of the nation's crossings don't have that kind of active safety equipment. They're considered passive crossings, with signs or markings on the road.

The Federal Railroad Administration tells Newsy, "not every crossing needs an active warning device system ... ." 

But many are still dangerous. 

Newsy mapped three passive warning crossings with the most fatalities in the U.S.: Six deaths at a crossing in Cross County, Arkansas; five dead at an intersection in Las Animas County, Colorado; and five deaths at a rail crossing in Christian County, Illinois. 

"Why aren't all crossings protected? It's expensive," Zarembski said. "And don't forget, by the way, a lot of the crossings are in the middle of nowhere. So if I'm putting lights and gates, I need power."

The new infrastructure law includes $3 billion to improve rail crossings across the country.
