Hundreds of migrants from Mexico were filmed boarding a US-bound train amid a record number of illegal crossings.

Footage released by Fox News on Sunday shows the FerroMex train passing through the central Mexican city of Zacatecas, heading north on a 750-mile journey to the United States.

Every carriage was packed with people cheering and clapping — with some hanging off the sides and waving to the camera.

As the New York Post reports, the video quickly went viral after it was posted on Twitter by Fox News’ Griff Jenkins, who captioned the post that the immigrants “obviously didn’t see the message, which says ‘don’t come.’

He was referring to Vice President Kamala Harris, who told Guatemalan migrants in June: “Don’t come. The United States will continue to enforce our laws and protect our borders.”
