CONCORD – A Bay Area Rapid Transit train partially derailed amid blistering temperatures Tuesday in Concord, causing minor injuries to passengers, authorities said.

Reported around 5:30 p.m. near Hastings Drive and David Avenue, the incident involved the last two cars of a 10-car train bound for San Francisco International Airport.

Roughly 50 passengers were evacuated from the train, according to the Contra Costa County Fire Protection District. A small number of them reported minor injuries.

Emergency responders checked on the passengers and at least one was taken to an area hospital for a complaint of back pain, said BART spokesperson Christopher Filippi.

Filippi said an initial assessment determined heat played the main role in the partial derailment by causing a curve in the rail between the Concord and Pleasant Hill stations. A high of 102 degrees was recorded in Concord, according to the National Weather Service.

Service was still stopped between the two stations in the Antioch and SFO directions as of late Tuesday. There was no estimate for when it would be restored.

“Right now, about 70 BART workers are on the scene helping to get the incident train out of the way and to repair the trackway,” Filippi said in an email to the Bay Area News Group just before 9:30 p.m. Tuesday.

For the morning commute, Filippi said BART anticipated at a minimum offering service that is reduced to one track through the area where the partial derailment occurred.

“We will work through the night and for as long as it takes to restore full service,” Filippi said.
