Biden slammed for breaking Amtrak cardinal rule during rail commutes to D.C.

Hey, keep it down, Mr. President!

That’s how some fellow Amtrak travelers are feeling with former President Joe Biden in their midst.

The ex-chief executive has been regularly taking the train from his home in Wilmington, Del., to his office in Washington, D.C.

And while many riders are loving seeing Biden riding the rails like an ordinary Joe, others have complained that he’s breaking one of Amtrak’s cardinal rules.

“He’s talking in the quiet car!” one irked rider complained to the New York Post.

Amtrak’s “quiet car” is the second on the Acela — behind first class— and its code of conduct is enforced by conductors and passengers who are quick to shush those who break the taboo.

Biden, who took Amtrak during his days in the U.S. Senate, also seems to have forgotten what’s on the menu in the Acela’s café car.

Biden is said to have asked for his favorite snack, ice cream, which isn’t served. The former leader of the free world had to settle for a muffin instead.

Biden, who dropped his re-election bid last year after a disastrous debate performance against now-President Donald Trump, has been visiting Washington, D.C., roughly once a week for meetings.

Passengers have shared Amtrak pictures of the ex-POTUS on social media, and Biden held an interview with CNN’s Dana Bash while aboard the train.

But Biden White House veterans say that there’s intrigue around what exactly the former president is doing at his temporary office, which is a short distance from D.C.’s Union Station.

“It’s really a mystery,” one former Biden aide said of Biden’s activities while in the district, adding that current Biden staffers “avoid answering” the question.

“They’re supposed to be setting up library stuff but no one has heard anything,” this person said. “We’re all wondering the same thing because he doesn’t go to restaurants or anything public around here.”
