The railway commuter system in Los Angeles will adopt new safety measures after a train crash apparently caused by an engineer's error killed 25 people nearly two weeks ago, officials said Thursday.

A series of commuter rail safety measures was unanimously approved Thursday by the board of Los Angeles Metropolitan Transportation Authority, which operates the region's railway commuter system, Metrolink.

The new measures include installing automatic train-stop technology, adding a second engineer to every train and installing video cameras and digital recorders in locomotive cabs.

Although an older technology, automatic train stops can halt a train in eight seconds. MTA officials said it is necessary to install the infrastructure now while waiting for a better technology to come along.

A Metrolink train carrying nearly 400 passengers collided with a freight train head-on on September 12, leaving 25 people dead and 135 others injured. It was the deadliest accident in the history of Metrolink, which began to serve the Los Angeles metropolitan area in 1992.

The crash occurred after the Metrolink engineer ignored a red light and slammed onto the freight coming from the opposite on the same track.
