ORINDA (KCBS/BCN) — Bay Area Rapid Transit trains were running on both tracks through the Orinda station Thursday morning after a mechanical problem that caused smoke to billow up from beneath a Pittsburg/Bay Point-bound train carrying passengers Wednesday evening, officials said.

Trains started moving in both directions about 6:20 a.m. but there were still residual delays after a train was stopped at the station when smoke was reported shortly after 6 p.m. on Wednesday, BART spokeswoman Alicia Trost said.

Trost said firefighters arrived at the station at about 6:20 p.m. and that the smoke was found to be coming from beneath the train.

Passengers were evacuated and the train went out of service, BART police Lt. Tyrone Forte said.

At about 3:50 a.m. BART officials announced that the train was on the tracks at the Orinda station Thursday morning and that crews were working to cut through a 1,600-pound metal motor reactor, which must be removed from the tracks before the train can be moved. The disabled train will then be moved to a yard for repairs.

According to Trost, the incident was not related to a reenactment held Wednesday of an accident that killed two workers on the tracks Saturday.
