A BART train partially derailed between the Orinda and Lafayette stations Monday morning, the transit agency said.
Nine people were transported to medical facilities to be evaluated, but none of their injuries were considered serious, according to BART.
The partial derailment of the eastbound Yellow Line train occurred shortly after 9 a.m. just outside the Orinda station, according to BART.
Two cars reportedly caught fire, BART said. Orinda firefighters extinguished the flames.
Passengers on the train were safely evacuated and escorted to the Orinda station by BART personnel, the transit agency said.
BART train service between Rockridge and Walnut Creek has been suspended while crews work to get the train back on track and repair the damage.
A crane arrived Monday at 4:40 p.m. to work on rerailing the train. The work is expected to last up to six hours, BART said, adding that two lanes of Highway 24 will be closed while work continues.
A bus bridge has been installed and provides full service between the Rockridge and Walnut Creek stations in both directions, BART said.
Other BART lines were not affected by the incident.
BART provided the following explanation for the derailment: “The derailment occurred at an interchange located between the Orinda and Lafayette BART stations shortly after 9 a.m. Just before the derailment, the train driver was instructed by the operations control center to manually align the route at the lock because a signaling problem prevented the computer from doing so. This procedure is not uncommon and train operators are trained to manually align routes. The operator then manually moved the train when it derailed. The train was not under automatic train control. Details of what happened are under investigation.
