Multiple workers were injured in an electrical explosion Monday morning at the Medical Center Metro station in , authorities said.

Rescue vehicles sped to the station just before 8 a.m., snarling traffic along Rockville Pike near the National Institutes of Health, but the station remained open to rail passengers.

The workers had been in an electrical shaft or vault at the station, said Pete Piringer, spokesman for the Fire and Rescue Service. One of them was taken to a hospital as a “priority one” patient with shocks or burns, Piringer said. Two others were transported in serious condition.

The cause of the explosion is being investigated.
