Fire officials say repeated air samples show no sign of a leak or spill after a freight train carrying hazardous materials partially derailed near M&T Bank Stadium in Baltimore.
Fire spokesman Captain Roman Clark says about a dozen cars of the 131-car CSX Transportation freight train came off the tracks about 8 a.m. Saturday.
One car turned over on its side. The train was traveling to Rocky Mount from Philadelphia. CSX spokesman Bob Sullivan says three of the derailed cars were haz-mat cars, two carrying a flammable resin.
One had residue of trichloroethane, a product in cleaning solutions that can be toxic if inhaled.
Sullivan says CSX hopes to have the track cleared by Sunday.
