A seven-alarm fire at a multistory warehouse in West Baltimore forced nearby residents to relocate and disrupted the MARC Penn Line, authorities said Monday, as more than 225 firefighters tried to get the flames under control.

Video shared with WJZ shows flames spreading to nearby trees and thick, dark smoke obscuring the view of a red water tower on top of the warehouse. Aerial photos showed large plumes of smoke and crews working from multiple angles to hit the warehouse with water.

The building, which is near the intersection of Edmondson Avenue and North Bentalou Street, stores mattresses, Fire Chief James W. Wallace said. The fire started at the back right of the building, which abuts the train tracks. Wallace said the warehouse also had two basement levels “stacked full” of mattresses.

Fire officials did not immediately say what they thought caused the fire. No injuries have been reported.

Some nearby residents were asked to temporarily relocate because of concerns about smoke and radiant heat, and to give fire crews better access to the warehouse, though officials are saying it is not an evacuation.

The American Red Cross of the National Capital& Greater Chesapeake Region is supporting residents who are being asked to temporarily leave their homes in the 600 block of North Bentalou Street, a spokesperson said.

Residents from fifteen households will be temporarily housed by the city in a hotel, a spokesperson for the American Red Cross said in an email.

Several city agencies are involved in the response to this fire, Wallace said, with the Baltimore City Department of Transportation assisting with traffic and the MTA helping to bus residents to a nearby fire station.

Around 9:30 p.m., smoke was visible on Doppler radar, according to WJZ’s meteorologist Derek Beasley. The relatively light winds Monday evening pushed the smoke plume north toward Druid Hill.

Beasley said the weather Monday evening is likely working in the fire crews’ favor, especially with rain in the forecast.

That’s a “huge difference” compared to what crews dealt with during the Camp Small fire at the end of 2024, where high winds fanned the flames of an inferno.

The Maryland Department of the Environment is advising people to avoid the area and to leave or move indoors if they feel affected by the smoke.

The Maryland Transit Administration said multiple MARC Penn Line trains were delayed or canceled.

Amtrak train service between Wilmington, Delaware, and Washington, D.C., has been paused. As of 10:30 p.m., officials said there was no timeline for when service would resume.

Firefighters got word of an ignition just before 7 p.m., Baltimore City Fire Department spokesperson John Marsh said.

The fire in West Baltimore happened the same day that a fire in downtown Baltimore injured two firefighters, one of them critically.
