Two people were killed after a car drove into a train Tuesday morning in Baltimore.

Baltimore Police Department Det. Jeremy Silbert told WBAL that the incident occurred around 6:30 a.m. Tuesday and involved a car and a Maryland Area Regional Commuter (MARC) train. The area had some rain at the time, but it’s unclear whether weather was a factor in the deadly collision.

The Baltimore Sun reported that the car involved was an SUV with two people inside. One of the occupants was declared dead at the scene while another was taken to a local hospital in critical condition but later died. Authorities have not released the names of the victims.

No one on the MARC train was injured, Maryland Transit Authority spokesman Paul Shepard told the Sun.

MARC service was suspended shortly after the collision, but trains are now up and running, according to WBAL.

The incident remains under investigation, ABC2 News reported.
