The wife of a conductor killed in the crash of an Amtrak train and a parked CSX freight train in South Carolina is suing Amtrak and the other rail company, saying they were to blame for the man's death.

Howard A. Spier, a partner with Rossman, Baumberger. Reboso & Spier in Miami, filed suit Thursday on behalf of Michael Cella's widow, Christine, and two children, Elena and Logan.

In the lawsuit, Christine Cella accuses Amtrak and Jacksonville-based CSX Corp. of negligence in the death of her husband. Michael Cella, 36, and Amtrak engineer Michael Kempf, 54, were killed early Sunday when their New York-to-Miami passenger train slammed into the CSX train stopped on a sidetrack. More than 100 passengers were injured.
