An Amtrak train carrying members of Congress — including House Speaker Paul Ryan — to a GOP retreat in West Virginia slammed into a garbage truck Wednesday, killing one person, the White House said.

No lawmakers or staffers were killed or seriously injured in the crash, according to the White House, although Rep. Jason Lewis (R-Minn.) was taken to the hospital with a possible concussion, his aides tweeted.

“I spoke with speaker Ryan … and they’re doing pretty good,” President Trump said at a press conference Wednesday afternoon.

“We don’t have a full understanding yet as to what happened, but it was a train hitting a truck, going at a pretty good speed … it looks like the driver of the truck was killed.”

Two train crew members and two passengers suffered minor injuries in the smash, Amtrak said.

Pols caught in the 11:20 a.m. collision recounted the episode first-hand.

“It just plowed into that truck. We didn’t know what it was until our car went by the garbage truck,” Rep. Mike Bishop (R-Mich.) told The Post.

“It was a forceful impact. You can tell we hit something substantial. The train jumped and lurched forward. It was a loud, loud bang.”

As Bishop relayed the disaster, emergency responders rushed to the scene, and police boarded the car carrying the GOPers — while lawmakers with medical experience joined in the rescue effort.

“There were multiple call outs for doctors,” said New York Rep. Lee Zeldin. “For the most part everyone stayed in their seats except if somebody was injured next to you, you would have a few members tend to that person until first aid arrived.”

Rep. Kevin Cramer (R-N.D.) was in the middle of a live interview with a local radio station when the accident occurred.

“Oh, Jesus, Sorry about that, we hit a bump here,” he told North Dakota’s AM 1100 The Flag. Later adding: “Valuable lesson, people. Do not challenge a train at a crossing.”

Around 300 politicians, aides and their family members were on their way for a retreat at The Greenbrier in White Sulphur Springs, West Virginia, starting Wednesday and ending Friday.

Vice President Mike Pence is scheduled to speak to members later Wednesday and President Trump is scheduled to address the event Thursday. The retreat will go ahead as scheduled, according to CNN.

Many pols were traveling with spouses and family and were sitting reading or casually milling about the train at the time of the crash.

Bishop noted that it was just last year that GOP members were practicing baseball when a crazed gunman shot up their practice, critically injuring Rep. Steve Scalise.

Bishop was sitting near fellow baseball team members and they remarked about living through another disaster together.

“It has not gone unnoticed. There are three of us sitting right next to each other who were at that baseball field and each of us has touched base on that very subject. You have to wonder why things happen the way they do. We’ve been through a lot together. It’s kind of scary,” he said.

“I don’t know how to get my head around this,” he added.
