Some Metro train operators are scared to operate trains in the wake of the recent deadly crash, according to their union president, despite the transit system’s assurance that it was a freak occurrence.

“We haven’t received anything that would make us think this was an isolated incident,” said Jackie Jeter, president of the Amalgamated Transit Union Local 689. “I do need to know that it is not going to happen again. I do have people out there who are afraid.”
