(Updates with details from fire department and transit agency)
Dec 4 (Reuters) - Commuters on a San Francisco Bay Area train were evacuated on Wednesday after reports of smoke coming from its brakes in a tunnel, and some passengers may have suffered smoke inhalation, authorities and local media said.
The Bay Area's KTVU television reported that about 300 people were evacuated from a transit station in the suburbs east of San Francisco. Transit officials said in a recorded message that train passengers were evacuated but did not say how many.
The Oakland Fire Department said on its Twitter feed that about 10 people were being treated at the Rockridge BART station in Oakland after as many as 15 passengers complained of smoke inhalation symptoms.
BART officials said the incident began at about 8:30 a.m. Wednesday, when the parking brakes of a train suddenly deployed in a tunnel in the hills around Berkeley.
An hour later, the transit agency said, the train had been repaired and was moving under its own power into the Rockridge station in nearby Oakland. At that point, passengers were evacuated from the train, the agency said.
The incident caused delays of up to 30 minutes on a line connecting San Francisco with some of its eastern suburbs, the agency said.
