CAMARILLO (CBSLA.com) —  At least two people were injured Friday morning when a Metrolink commuter train and a big rig collided in Camarillo.

The accident took place around 6 a.m. when the train was headed eastbound from the Oxnard Station to Camarillo near 5th and E. Pleasant Valley Road.

“This is a private, uncontrolled crossing other than there’s a stop sign at the crossing. But this is a private road going to an agricultural field.” CHP Sgt. Bruce Clark told CBS2′s Amy Johnson. “The flatbed truck, which was towing a flatbed trailer, which had a field apparatus on it, attempted to cross in front of the Metrolink train. The engineer saw it and slowed significantly, so it’s not a real high-speed impact because the train was originally going less than 60 miles per hour.”

The driver and a male passenger in the truck were taken to the hospital with unknown injuries.

A woman on the train was also hospitalized after suffering an anxiety attack.

Environmental crews were called to clean up a small amount of spilled diesel fuel that leaked from the truck during the accident.

The train has been removed and the track is reopened.

It is unknown why the truck was on the tracks at the time of the collision, but train experts say it can be difficult to detect a train’s speed and recommend drivers wait until the train has passed, particularly in areas where the crossing is not protected by flashing lights and a guard.
