One person has died and dozens were injured, 11 of them “very seriously,” after two passenger trains collided north of London on Friday, U.K. emergency services said.

The crash occurred late afternoon near Bedford, a town around 90 kilometers north of the U.K. capital, and involved two London-bound trains on the same track, according to East Midlands Railway (EMR).

“There was a moment of being flung into the chair in front, and then I saw smoke. People were crying, screaming, people were so scared and confused,” passenger Pete Knapp told the Press Association news agency.
