Federal investigators and the National Transportation Safety Board have confirmed that Robert Sanchez, the engineer operating the Metrolink train which crashed last Friday, was sending text messages moments before the deadly collision which left 25 dead and another 135 injured.

Currently, there is no federal or state law which prevents the use of cell phones used by railroad employees. Yesterday, the California Public Utilities Commission unanimously passed an emergency order to ban the use of mobile phones and other personal electronic devices while operating a train.
