Trains have started running on MARC’s Brunswick Line again, two and a half hours after a MARC train and a dump truck crashed in Montgomery County.

The driver of the dump truck was the only person injured, and Montgomery County police spokesman Rick Goodale said that his injuries were minor.

Goodale said that approximately 600 passengers were on board the train when it crashed at 4:46 p.m.

Shortly after 7 p.m., MARC said those passengers were still at the site of the crash, between the Silver Spring and Kensington stations, and were being transferred to a new train to continue traveling. Additional Brunswick Line trains would depart from Washington after that train comes through, MARC said.

The railroad said that the crash might continue to cause delayed service on Tuesday morning.

Goodale said emergency responders do not yet know what caused the crash, which happened near the intersection of Forest Glen Road and Seminary Road in Silver Spring, just outside the Capital Beltway.

Throughout most of the evening commute, trains did not run anywhere on the Brunswick Line, which travels all the way from Union Station in the District to Martinsburg, W. Va., stopping at stations including Rockville, Gaithersburg and Germantown on the way.

Seminary Road remains closed in both directions, and the block of Capitol View Avenue from Beechbank Road to Forest Glen Road is closed as well. Police said on Twitter that spilled diesel fuel would keep the intersection closed for a long time.
