Metrolink and its former contractor Connex Railroad agreed last week to set up the fund. Their court filing signified they accept maximum liability for the tragedy that killed 25 people and injured more than 100 others.

A spokesman says the Republican congressman is considering a bill to change the law that Congress adopted in 1997 as part of the reauthorization of Amtrak.
