Earns CSX

BALTIMORE (AP) — Authorities say it appears that a mechanical problem caused a freight train derailment in a tunnel in Baltimore, but the specific cause is under investigation.

CSX spokesman Rob Doolittle said at least 13 cars derailed early Monday in the Howard Street tunnel, but there were no injuries or hazards to the public.

Doolittle says the 124-car train was headed from Philadelphia to Cumberland, Maryland, with eight locomotives. He says one derailed car contains acetone, a flammable solvent. Rail traffic was stopped in the area.

Fire department spokesman Samuel Johnson says no poisonous substances were released and no chemicals leaked out of the derailed cars. He says other chemicals on the train include butane and liquefied petroleum gas.
