OAKLAND, Calif. (KRON) — Two injured people have been transported to local hospitals after a train and a railroad vehicle had an accident in Oakland, near 50th Avenue, according to a tweet from the Oakland Fire Department midday Friday. One of the people transported and treated was a passenger on the train. The other was the operator of the front loader tractor that the train collided with.

The accident happened near 50th Avenue in east Oakland. Rail traffic has stopped in both directions.

The Oakland Fire Department HazMat team has been deployed to the scene by the incident commander, according to a subsequent tweet from the Oakland FD. The team will “investigate and assess reports of a 1200 gallon diesel tank at the scene, and its potential impacts,” the tweet states.

In a later afternoon update, there were likely between 100-700 gallons of diesel oil that leaked across the train tracks, Michael Hunt of the Oakland Fire Department told KRON4.

CalOSHA and investigators from the National Transportation Safety Board are en route to the scene, according to a tweet from Oakland FD. Thirty train passengers remain in the train car awaiting transfer from the scene.

The department promises more details will be released later. As of 12:50 p.m., the Oakland Fire Department says there is no threat to public safety.
