All CTA lines on the Red Line are shut down north of Armitage Avenue and south of Belmont Avenue because of an extra-alarm fire in a building along the tracks on Sheffield Avenue in Lincoln Park near DePaul University.

Fire Department crews were called to Roy’s Home Furnishings, 2455 N. Sheffield Ave., about 3:20 p.m. A 3-11 alarm was called by about 3:45 p.m.

The building was “totally involved” with heavy smoke and fire damage, according to the Chicago Fire Department. As of just before 5 p.m., crews were still pouring water on the fire from outside the building, and there were no reports of injuries. Video from the scene showed firefighters aiming water into the building from hoses on the street and at least one ladder truck, as grey smoke billowed up over the neighborhood.

Southbound Red and Brown line trains are being turned back north at Belmont. The Purple Line is Express is suspended. Service on the Brown Line was suspended between Southport and Sedgwick, and on the Red Line north of the Clybourn station, according to the CTA.

Bus shuttles running along the “L” lines and the No. 11/Lincoln bus also is affected.

Red Cross volunteers were headed to the area to provide water for firefighters, the organization said.
