The 2015 Oxnard train derailment occurred on February 24, 2015, at 5:44 a.m. local time when a Metrolink passenger train collided with a truck that a driver had mistakenly turned from Rice Avenue onto the tracks and became stuck. After impact, the train derailed at Oxnard, California, United States. As a result of the crash, the train engineer died from his injuries a week later and 32 passengers and crew members were injured. The truck driver exited his vehicle and ran from the scene prior to the crash; he sustained minor injuries that were unrelated to the crash sequence.

A control car, cab car, control trailer, or driving trailer is a non-powered rail vehicle from which a train can be operated. As dedicated vehicles or regular passenger cars, they have one or two driver compartments with all the controls and gauges required to remotely operate the locomotive, including exterior locomotive equipment such as horns, bells, ploughs, and lights. They also have communications and safety systems such as GSM-R or European Train Control System (ETCS). Control cars enable push-pull operation when located on the end of a train opposite its locomotive by allowing the train to reverse direction at a terminus without moving the locomotive or turning the train around.
