LUDLOW (CBSLA) — A freight train derailed in the Southern California desert on Wednesday, sending more than 40 rail cars crashing into the sand, authorities said.

The derailment happened just before 4 p.m. Wednesday and left the rail cars scattered haphazardly on the tracks east of Ludlow, and north of National Trails Highway.

San Bernardino County Fire released drone photos and video of the derailment, which showed dozens of rail cars lying across the tracks. Several rail cars also appeared to have been pushed down an embankment.

No injuries were reported, and there was no impact to nearby I-40, according to San Bernardino County Fire officials.

However, a hazmat crew was called out to clean up flammable liquid that spilled from a round tank car. The leak was mitigated, San Bernardino County Fire said, but  the hazmat crew and BNSF Railway remained on the scene for the cleanup.
