"Yes, Metrolink. He was an employee and receiving a pay check and benefits from Metro. Therefore, Metrolink is culpable."

From the L.A. Times Article:

The NTSB said Tuesday that Sanchez was hired by Union Pacific in 1996. In 1998, he went to work for Amtrak, then he was hired by a contractor to work for Metrolink in 2005.

“...to work for...”

Who is paying the contractor? Metronlink. If Metrolink was not culpable, why did their PR official resign. After all, it was the contractors responsibility. Using your argument, the focus should solely be on the contractor. The reason it is not is because the engineer, ultimately, works for Metro.

Now, I would not be surprised if the families of the victims filed a lawsuit against the contractor as well. As I said, Metronlink is responsible.
