The brakeman on the freight train in a deadly collision near Los Angeles is suing the other railroad and the companies that provide its engineers.

Dominick Fravola and his wife sued Friday in Los Angeles Superior Court. They say the Sept. 12 crash happened because the defendants allowed dangerous conditions to persist.

The lawsuit seeks an unspecified amount in damages, medical and psychological expenses and loss of income. His wife also seeks damages for loss of consortium.

The lawsuit names the Metrolink service, as well as Veolia Transportation and a subsidiary. Metrolink and Veolia declined to comment.

In the accident, a Metrolink train ran a red signal and collided with the Union Pacific freight. Twenty-five people died.
