(KRON) -- A traffic accident shut down BART service in the East Bay Tuesday, according to the California Highway Patrol. BART service was stopped between the Castro Valley and West Dublin/Pleasanton stations due to an obstruction on the track, BART wrote in a social media post. CHP told KRON4 News there was a collision involving a semi-truck, a tow truck and an unoccupied vehicle that was being carried by the tow truck. The unoccupied vehicle appeared to have been ejected and landed on the BART tracks, sparking a brush fire.
