A massive Monday night fire has been contained to its original warehouse building in West Baltimore after drawing a response of about 200 firefighters, officials say.

More than 200 firefighters battled a massive blaze that broke out at a west Baltimore warehouse, disrupting Amtrak service in the area and prompting officials to move dozens of area residents. Commuter rail service was canceled Tuesday amid fears the building could collapse onto railroad tracks.

Firefighters remain on the scene Tuesday hitting hotspots and deep-seeded fires in the multi-story mattress warehouse.
